Abstract: We addresses the need and issues in WDM networks with traffic grooming capabilities, supporting lower-rate circuit-switched traffic streams. Traffic grooming in WDM networks, is defined as the act of multiplexing, demultiplexing and switching lower rate traffic streams onto higher capacity lightpaths. In such a network, in addition to add/drop and full wavelength switching features, some or all of the network nodes can be provided with the capability to switch lower-rate traffic streams from one wavelength on an input port to another wavelength on an output port. We will also discuss restoration algorithm to maintain high performance and reliability. A new architecture, called Light Trails, being implemented at ISU that deploys switch-less traffic grooming for LAN and MAN applications will also be described
Abstract: In this talk, a brief introduction to the field of Spintonics and its potential with particular relevance to the existing applications will be given. Thereafter, I shall discuss an interesting class of hybrid devices (Semiconductor/ferromagnet) like the Spin-Valve Transistor and the Magnetic Tunnel Transistor, which are based on the spin dependent transport of non-equilibrium carriers. Important device characteristics and performance, and the underlying physics essential for the operation of such devices will also be discussed. Finally, our recent results on the first observation of spin filtering of hot holes in a similar system using the technique of Ballistic Hole emission Microscopy will be presented.
About the Speaker Dr (Ms) Tamalika Banerjee did M.Sc. at University of Calcutta and Ph.D. at University of Madras in the year 2000. Her Ph.D. work was on Oxygen irradiation effects in Pb and Pb-Sn doped Bi-2223 superconductors, for which she extensively used the accelerator facilities at Nuclear Science Centre, New Delhi and obtained the Best Thesis Award from Indian Physics Association in December 1999. In May 2000, she joined Tata Institute of Fundamental Research (TIFR) as a Post Doctoral Fellow to work on Vortex dynamics in superconductor thin films at microwave frequencies. Here, she was a member of the team which observed for the first time the Peak Effect (PE) phenomenon in laser ablated DyBa2Cu3O7-d and YBa2Cu3O7-d thin films at microwave frequencies, and contributed significantly in the understanding of the PE phenomenon.
Although Dr. Banerjee had carried out some work on Spin-injection in superconductor-ferromagnet heterostructures while at TIFR, her major contribution in Spin-electronics or Spintronics during the last 3 years is at MESA+ Institute of Nano technology, University of Twente, The Netherlands where she is currently working. MESA+ Institute is an important centre for Spintronics where the first Spin Valve Transistor (SVT) was invented in 1995. Although Spintronics has a high potential, its eventual success will depend upon the coexistence of silicon device unit processes with the ferromagnetic layers. Dr. Banerjee has made significant contributions in areas such as SVTs, Magnetic Tunnel Transistors (MTTs) and the recent work on the first observation of spin filtering of hot holes using the technique of Ballistic Hole Emission Microscopy.

Abstract: Gallium Nitride based transistors have emerged as an exciting candidate for high power RF applications. The physical constants of gallium nitride, like wide band gap (3.4 eV), high saturation velocity (2.8E7 cm/s), high breakdown field ( > 3 MV/cm) and the spontaneous polarization gives it an inherent advantage compared to other material systems like Silicon or Gallium Arsenide for high power applications. Heterostructure field effect transistors were fabricated on AlGaN/GaN heterostructures grown both on sapphire and silicon carbide substrates. Typical DC currents measured was over 1 amp/mm and transconductance over 250 mS/mm. Small signal measurements on a device with 0.3 micron gate length gave Ft of 33 GHz.RF power was measured at 10 GHz, and a 100 micron periphery device ouput a saturated power density of 11.7 W/mm. This is ten times higher power density than on Gallium Arsenide based transistors at this frequency. To achieve high RF power densities, the sample needs to be passivated using PECVD silicon nitride. A 1.5 mm device was fabricated, which output a saturated power density of 5.6 W/mm at 10 GHz. We shall discuss the trade offs involved in scaling the device to achieve high power densities seen in small periphery devices. Another potential application of Gallium Nitride based devices is in the field of harsh environment sensors. Pt based Schottky diodes were fabricated on 1X1017 cm-3 n doped GaN. These devices were exposed to hydrogen to temperatures upto 365C. The devices showed sensitivity to hydrogen and the sensitivity was found to be diffusion limited.

Abstract: The availability of secure, reliable and high quality electric power is critical for meeting the needs of a modern industrial economy. Maintaining the availability of reliable and cost-effective electricity in the face of increasing congestion, an aging power delivery infrastructure and mushrooming energy consumption, poses a technical, regulatory and financial challenge. Improving the utilization of existing assets can unlock the value that is trapped in the T&D infrastructure. Active power flow control, VAR compensation and grid-monitoring are key technologies that can dramatically improve grid utilization, while improving system reliability. The second, possibly more important impact, especially for high-tech manufacturers, is power quality, and the unscheduled downtime that results from power disturbances occurring on the grid. This presentation will also look at the impact of the various types of power disturbances on typical industrial equipment and processes. Based on the underlying phenomenon associated with power disturbances, and on actual data measured across hundreds of industrial installations, a strategy is presented for understanding and then finding a solution for the problem of unscheduled downtime. Different types of solutions are discussed including UPS, voltage sag compensators, active filters and ride-through devices for application at a plant, bus or machine level. Industry standards from organizations such as SEMI, IEEE, ITIC and IEC are also discussed. Case studies from various manufacturing sectors, including semiconductors, automotive, food, plastics and fiber optics, show how the problems were identified and resolved.
Abstract: Study of fundamental electronic properties in material Si: the most important material in modern VLSI circuits, stands in its own merit. Electron mobility under ohmic and high field condition is an important physical parameter, the knowledge of which is needed in device modeling. With downsizing of basic FETs, new phenomena like quantization of electron motion, tunneling, hot electron injection etc. creep in and they require thorough investigation. Furthermore, alternative technologies like SiGe/Si heterojunctions, SiC, are being introduced to realize better digital and analog devices and study of basic processes in them is assuming importance. In the present talk, the transport phenomena in silicon and its alloys and quantum heterostructures will be described and the methods of analyzing the data will be described. The strain induced band gap engineering and mobility enhancement will also be mentioned. The knowledge acquired from the studies will be applied to investigate the performance of newer Si based photonic devices, like Quantum Cascade Lasers, QWIPs, already developed using compound semiconductors.
Abstract: In sub-micron damascene Cu interconnects, the dominant role of interfacial diffusion at the Cu/dielectric cap interface is widely accepted.Thus the role of the interfacial structure, composition, adhesion, is expected to play a significant role in determining the electromigration lifetime of the advanced interconnects. However, the inter-relationship of all these factors, materials, processes, and the dual damascene architecture on the void nucleation, growth, and eventual failure is still far from understood. In this study the effect of reducing, inert, and reactive gas treatments so as to induce compositional changes at the interface as well as different cap layers including silicon carbides, nitrides and their variants were studied. Upper and lower level test structures were subjected to different treatments after CMP and the electromigration performance was assessed on the package level. In untreated samples, the asymmetry of the test structures leads to higher MTFs for the upper layer test structures; however it was determined that upon surface treatments, the MTFs of lower layer test structures showed a 2x improvement and could achieve lifetimes comparable to the upper layer test structures. The role of the interfacial composition and microstructure on this improvement was studied through TEM and XPS and the role of interfacial adhesion was studied using four point adhesion tests and nano scratch tests. In order to completely characterize the effect of the interface on electromigration and to determine the nature of void nucleation, growth, and void migration; in-situ SEM electromigration experiments were carried out and the observed results indicate that the void formation is controlled through heterogeneous nucleation at the interface.

Abstract: This talk will focus on results from the measurement of resonance in structures at micron and nanometer scales. Due to their size, such small resonant structures have the potential for commercial instruments with sensitivities high enough for unprecedented sensing applications, such as the detection of pathogens and biomolecules, and well resolved measurement of gradients of fluid properties. We will look at two types of structures: paddle-beam oscillators made by conventional micromachining and nanowires, which are grown off-chip and can be surface-treated in batches before assembly, for versatility in sensing applications. Experiments with a paddle beam oscillator showing both nonlinear softening and stiffening are understood through a nonlinear oscillator model with coefficients dependent on thermal stress. Results for beam oscillator behaviour in a gaseous environment in continuum, free molecular and transition regimes and an open problem of unsteady flow in the transition regime will be presented.

Abstract: HW/SW Co-Design of MPEG-4 Video Decoder on Excalibur chip
MPEG-4 Video Decoder was implemented using Altera Excalibur chip that has 400,000 PLD gates and an ARM 922T core. Among MPEG-4 Video Decoder blocks, IDCT and M.C. (Motion Compensation) blocks have more calculation complexity than other blocks. IDCT and M.C. blocks was implemented hardware IP on PLD area and the other blocks will be implemented by software on ARM922 core in order to reduce total operation cycles.
FPGA Implementation of RTE-LDPC Encoder/Decoder Decoder procedure of LDPC (Lower Density Parity Check) is based on IBPA (Iterative Belief Propagation Algorithm) compared with turbo codes’ BCJR Algorithm. LDPC is not only reduced a delay time and a computational complexity but got a global convergence. However, this procedure has an inordinate demand of calculation operations. To do overcome this demand, RTE (Real Time Encodable)-LDPCs design is required. The FPGA implementation will be based on an algorithm based on Ping and Echard’s paper. The performance of FPGA will be verification using Excalibur chip.

Abstract: Linear models have provided the foundation for the theory and techniques supporting most of the technological developments of the past century. However, natural and artificial systems which possess some form of computational intelligence, like the human brain, are, in general, large-scale, parallel, distributed, and nonlinear (ls/p/d/nl). With the explosive growth and enormous potential of information technologies (IT) in this new century, it is of paramount interest to develop a rigorous framework for modeling identification and design ls/p/d/nl systems capable of performing computationally intelligent tasks. Motivated by these considerations, we will present in this lecture a space F(X) where the input/output maps f of ls/p/d/nl systems may reside. In mathematical terms, F(X) is a Reproducing Kernel Hilbert Space of nonlinear (not-necessarily linear) analytic functionals (abstract Volterra series) on a given input vector space X. In general, f will consist of a m-tuple of maps in F(X). We will show how a solution to the problem of optimal identification or design of f is obtained by an orthogonal projection in F subject to input-output data constraints or design specification constraints. Such a solution naturally appears in the form a feed-forward or recurrent neural system. We will briefly discuss the processes of adaptation, learning, evolution, discovery, and invention by such systems. Examples with simulated and real data will be presented.

Abstract: Growing competition between network operators, new characteristics of traffic as well as network survivability challenges trigger the need to migrate from SDH/SONET-based networks to a more flexible and dynamic optical infrastructure. The proposed lecture will present current standards and concepts related to such an infrastructure and ways to implement it in real networks, along with challenges facing designers and system engineers. The lecture presents migration from current networks towards Automatic Switched Optical Networks (ASON) that give the means to deliver end-to-end, managed bandwidth services efficiently, expediently and at reduced cost. Current status of optical networking is outlined and driving forces behind ASON are enumerated. Transport, control, and management planes of ASON are described, including such issues as: optical cross-connects, control plane models, and management of optical networks. Approaches to service resilience in optical networks using the ASON functionality are reviewed. The lecture is concluded by presenting current standardization activities, open issues and perspectives of ASON.

Half-day Workshop on “The Art of Analog Design”
Abstract: The International Technology Roadmap for Semiconductors (ITRS) is predicting the technology evolution for the coming 15 years, required to give the semiconductor industry a competitive market position. This not only implies pushing existing process modules to the limits but also introducing new ones, which most likely will be based on alternative concepts and/or the use of new materials. This presentation will be focusing on a selection of these processing challenges. First the silicon material requirements will be addressed, including high quality silicon substrates, epitaxial wafers, thin film SOI, SiGe and strained silicon. Subsequently some process modules will be discusses such as e.g. as isolation schemes, gate dielectrics based on high-k materials, silicides and interconnect schemes. Beside the use of novel or alternative materials, attention will also be given to equipment aspects like atomic layer deposition, single wafer processing, flash annealing, etc The last part will outline the importance of so-called gate engineering, including metal gates, doubles gate structures, vertical replacement gates and FinFETS. These approaches are presently extensive studied and will surely be used for the 45 nm and below emerging silicon technologies.

Abstract: Incorporation of nitrogen into the gate dielectric has been well known to reduce gate leakage for CMOS devices. However, for 65nm technology, the scaling down in conventional methods of nitridation (Rapid Thermal Nitridation and Furnace Oxynitride) processes of gate dielectric has not proven to be useful due to intolerable gate leakage currents coupled with poor device performance. In addition, conventional nitrided gate dielectrics have also been found to be a major concern for reliability. Recent developments in plasma nitridation processes have been proven to be successful not only in meeting the CMOS platform requirements but also in supporting the 300mm activities. Single wafer plasma nitridation tools in the 300mm facility have been found to introduce substantial amounts of nitrogen into the gate dielectric, thus leading to reduced gate leakage currents, without causing degradation in the device performance. XPS and D2R (Delay to Re-oxidation) techniques have been developed to monitor the nitrogen dose and profile routinely in the thin gate dielectric. This talk focuses on the recent developments in gate dielectrics at Crolles, France (Motorola, STMicroelectronics, and Philips alliance team) for 65nm technology and possibly even for future generations.

Abstract: He has witnessed distributed generation (small city systems & captive generations) evolving into huge regional power grids though his career spanning over 53 years by now. The scenario is changing again. Standards have been evolved on interconnections, surge problems, etc.
Deregulation of the power industry is changing the playing field and providing customers new opportunities to have more input into the type and quality of their electric service. This is providing an opportunity for the re-birth of distributed energy resources (DER) or distributed resources (DR). The development of the modern DR and its utilization is taking many forms. Some are being operated to back up existing electrical facilities, others are the prime source of electricity, operating individually or in a microgrid and others are being operated as an integral part of the existing electric supply system.
This tutorial will review the evolution of DR, the types of DR and their characteristics, the problems and requirements associated with operations in a microgrid and in the integration with an existing electrical system. Consideration will be given to operation limitations, protection, control, communications and safety issues. There will be a discussion of some typical installations such as combined cycle installation and efficiencies.
Some material will address the problems associated with the interconnection of DR on electrical power distribution systems. Key to the success of the discussions will be the understanding of the terminology by all of the participants, including the instructor.
The tutorial will focus on the recent development of IEEE 1547.1 Interconnection of DR and other standards under development in the 1547 series of standards. This will be an interactive tutorial where the participants will have an opportunity to raise issues and have them discussed by the participants.

Abstract: Both service providers and enterprise IT are facing the problem of rising OpEx (Operational Expenses) and complexity of managing the infrastructure. In addition, service providers lack visibility into network traffic to offer value-added services such as prevention of DOS (Denial of Service) attacks, virtual network services and SLAs based on differentiated services. This talk, will describe the problem of creating robust IP-based network infrastructure that supports value-added services.

Abstract: Stochastic wiring distribution models based upon Rent’s rule have been in use for the design of multilevel interconnect systems for microprocessors. A methodology and a performance metric to design a multilevel interconnect architecture that was developed earlier is presented. One of its features is the ability to predict the wiring requirements, the area (die size) of the microprocessor chip or macrocell, and the length distribution of the wires. As microprocessor clock frequencies increase well into the gigahertz domain, increasing attention is being paid to the role of interconnects as both performance limiters and their role in design and manufacturing complexity. In this regard system level interconnect prediction is likely to play an important role in managing these complexities, and an overview of metrics, models and issues relevant to the design of the interconnect process architecture is provided.

Abstract: Nanocrystalline Si:H (sometimes also called microcrystalliine Si:H) is a new electronic material where the grain size is extremely small, of the order of 10-30 nm. It is deposited at low temperatures (< 350 C) using plasma deposition from a mixture of hydrogen and silane, though under some circumstances, one can deposit it without using any additional hydrogen. The grain size can be controlled by controlling temperatures, hydrogen dilution ratio and ion bombardment during growth. The presence of hydrogen in the material is critical. H both passivates the grain boundaries, and makes possible the crystallization process because of its etching effect during growth. In spite of the small grain size, the material has very good electronic properties, with Hall mobilities in the range of 10 cm2/V-sec, and hole diffusion lengths of up to 10 micrometers. The material can be doped both n and p type, thereby making devices possible. The optical properties resemble those of crystalline Si, but with an enhanced absorption due to internal scattering at grain boundaries. In this talk, I will discuss the nature of the material, and its structural, optical and electronic properties. I will also discuss device applications and device designs, including thin film transistors and solar cells. This material may offer the potential of building good devices on plastic substrates, including “wearable” electronic devices, as well as the potential of making thin film, low cost, crystalline Si solar cells of > 15 % efficiency.

Abstract: The dynamic power consumption of a CMOS circuit is at least an order of magnitude greater than the other components such as the short-circuit and steady-state power. We prove that the minimum dynamic power design, which is completely free from glitches, is obtained when the differential path delay at every gate is less than the inertial delay of the gate. When the overall input to output delay is also constrained, we obtain the minimum power design by a linear program (LP) consisting of an inequality set whose size is linear in the circuit size. The LP determines the delays for all gates. For physical implementation, we express the delays of CMOS gates as linear functions of the length/width ratios of transistors. Routing delays are entered in the LP as constants and their values are determined through iterations of the LP and physical layout. The optimized design of the benchmark c7552 consumes 38% average power as compared to the original unoptimized circuit.

Abstract: Over the past few years, the semiconductor industry has morphed through a transformation driven by technology and economics. The impact has been that an industry formerly dominated by large vertically-integrated players following a “do-it-all-yourself” business model has given way to an “atomized” ecosystem, with a large number of players of varying sizes and following varying business models. There are two primary drivers of this transformation – one, the sheer cost of developing process technology at advanced nodes (e.g., <= 130 nm) and two, the increasing complexity of design. This has caused separation of process and design, and has fueled the rise of the foundry business model, where the foundries have emerged as the aggregators of manufacturing capacity. In conjunction, many players have emerged that follow capital-light, “fabless” business models, which include providing designs, intellectual property, cell libraries, embedded software, consulting and project management services. The new industry structure will inevitably be more complex, and the complexity is further intensified by the geographic dispersion of activities. In particular, the greater China region has emerged as a strong player in manufacturing, and is increasingly seeking a leading role in Design/Product R&D as well as Process R&D. These changes are altering not just the business systems, but are fundamentally altering both the nature and ownership of R&D activities. In this talk we will explore this industry transformation, and the implications for industry and academia.

Abstract: Technological innovation in the areas of lithography, novel materials, and device design has made relentless strides in the microelectronics area over the last few decades. We will begin by highlighting recent developments in these areas at IBM. However, further returns in functionality and performance will come through the use of system level integration on chip ? often referred to as the System on a Chip (SOC). A key component of the an SOC is the memory subsystem which has traditionally been the purview of SRAM. However, the need for increased density, and the fact that further scaling of device technology results in a concomitant increase of standby power, as well as an increase in soft error rates (SER) are severe limitations. We have successfully embedded DRAM in to advanced logic technologies without compromising logic performance. We describe our deep trench-based technology and embedded DRAM macro concepts, which we are extending well into the 65nm node for both bulk and SOI technologies. This technology is now a critical component of modern network switches and high-end server caches including the IBM Blue Gene supercomputer. Another aspect of the SOC era is the integration of test and repair function on chip. We will describe our built-in test and repair methodology using a novel type of electrical fuse element and discuss the concept of autonomic chips that have the potential for self-diagnosis and self-repair.

Abstract: Power electronics (PE) has a long history and evolving development since the beginning of electro-physics in the eighteenth century with the concept of the `semiconductor’. Its technology has gone through an unanticipated rapid growth in the last forty years. The presentation begins with a plausible definition and the goal of power electronics with its key features and application areas for a better understanding, and traces ,chronologically, the major significant events / breakthroughs in the past history ( since 1783 ) till the birth of the Silicon Controlled Rectifiers in 1957 , that shaped the growth of PE as it today. Then, the evolution of modern power electronics as a complex multidisciplinary technology synthesizing a number of diverse disciplines such as power switching devices, new materials, microelectronics , converter topologies, controls, integration and packaging technologies, and its continuing applications to all cases of power processing: generation, transmission, distribution and utilization (including machine drives) have been dealt with, again in a chronological order, till the present date. The objective is to make an attempt for a comprehensive review of the past and the present status of the developments in PE in almost all possible areas and to assess the future trends of this dynamic technology in the next few years of the 21st Century. It is demonstrated that in the highly automated and economically competitive environment worldwide in this century, the PE will truly be a key enabling technology in every field.
Abstract: Electricity, power tools, and automation in factories, began the Industrial Age at the end of the Depression in the last century. After the Second World War, we entered the Atomic Age which gave us the technology to build nuclear power plants for production of, the so-called, cheap electricity during the decades of the fifties and the sixties. Challenge to land the man on the moon and bring him back safely started the decades of the Space Age. Advancements in microelectronics, computers, and the Internet brought in the Information Age, bringing with it productivity gains in the white-collar workers of the industry and the dotcom revolution, during the last decade of the past century. Rapid expansion of economies throughout the world, and simultaneous increase in standards of living, for an exponentially growing population, have started to increase pressures on energy demand for both fossil fuels and electricity as we embark upon this new century and the third millennium. We, therefore, have now entered the Energy Age. This seminar will cover topics related to the management of electrical power. After a brief background on energy consumption trends and power quality and reliability concerns, both supply side and demand side issues would be presented.

Abstract: Advances in micro and nanotechnologies are now finding wide spread applications in biomedical research and these technologies are penetrating even industrial and clinical practice. Excellent examples of research devices can be found in neuroscience research and examples of industrial devices can be found in gene expression and lab on a chip devices. My talk will review several methods, from simple ones that use microcontact printing to make sensors to more advanced ones that use photolithographic and nanofabrication approaches. I will focus on numerous advanced probes, sensors, and MEMS devices developed for neuroscience research. These include neurochemical and electrical sensors, microdrive mechansims and our latest work on nanosensors (all developed by various IIT grads and alumni!). The interface of brain research and micro/nanotechnologies is certainly a very fertile field for development and my talk will stimulate ideas for future projects, interdisciplinary work and collaborations.
Abstract:Wireless systems in which multiple antennas are used at the transmitter and receiver (MIMO systems) have generated considerable interest in recent years. This talk will begin with a review of single antenna cellular systems and the traditional comparison of orthogonal multiaccess techniques (such as TDMA/FDMA) with non-orthogonal code division multiaccess (CDMA). The comparison is based on the achievable spectral efficiency in bits/s/Hz/cell. For delay-sensitive traffic (e.g., voice), the reasons for the alleged superiority of CDMA are discussed. The effect of using multiple antennas at the receiver and transmitter of the uplink is then considered in some detail. For fading channels, the spectral efficiency can be calculated based on ergodic or outage measures, and both measures are discussed. While the spectral efficiency calculation for orthogonal multiacccess with multiple antennas follows straightforwardly from a single user analysis, this calculation is considerably more complicated for CDMA. For the CDMA system, we will restrict our analysis to the case where the receiver performs single user decoding that follows possible multiuser detection. Our calculations indicate that the superiority of CDMA continues to hold with multiple antennas, and is in fact considerably more pronounced. For example, with one transmit antenna and a sufficient number of receive antennas, the (ergodic) spectral efficiency of CDMA with just single-user matched-filter detection is better than that of orthogonal multiaccess, even on a single cell basis. We also argue that transmit diversity does not improve the spectral efficiency of the CDMA system significantly. We end by commenting on the usefulness of space-time coding when combined with CDMA on the uplink.

Abstract:Reliability is one of the most important requirements for the embedded systems since these systems should run with little or no human intervention. Unlike desktop and server systems, embedded systems cannot ask for operator help when application encounters a problem. Due to this High Availability (HA) is one of the hottest topics for the embedded design. Although most of the reliability problems are related to device design and technology some of the failures such as single event upset can only be taken care at design stage. This talk will review some of these mechanisms and design techniques used to make these chips robust. Talk will also briefly cover some of the other projects in computational electromagnetics and electronics division at Institute of High Performance Computing.
Abstract: Basic factors for a highly reliable power system design include the following:

Abstract: Following its first demonstration in 1960 at Bell Labs, the understanding of the intrinsic noise mechanisms in the MOSFET quickly followed. However, as technology improved, the discovery and understanding of a host of other noise mechanisms slowly evolved over time. In this presentation, we will introduce the concept of random noise and describe its manifestation in the context of the MOSFET structure. This includes channel thermal noise, gate-induced noise, gate resistance noise, substrate resistance noise, substrate current supershot noise, bulk charge induced transconductance reduction noise and channel hot carrier noise. We will also discuss changes in the device structure to improve the noise performance by suppressing the effects of the extrinsic noise mechanisms. This work has resulted in almost an order of magnitude improvement in the noise performance of these devices making them suitable for lightwave and wireless communication applications.

Abstract:Internet and IP based services have been the focus of networks and services all over the world. Attempts are being made to move the present circuit switched services to the new IP world, and creating new carrier class packet based services from narrow band telemetry to broadband, multimedia and 3G wireless. Serious difficulties arise in ensuring a good quality of service- QoS due to the basic difference in the characteristics of the modes of transport. This is further aggravated by the emergence and demand of several new innovative services. Management of these problems requires techniques for bandwidth and delay control, like the MultiProtocol Label Switching-MPLS, ability to handle streams, integrated network management and security. New architectures focus on Softswitches and Gateways, the basic building blocks of the Next Generation Networks-NGN. I plan to discuss these and related issues in my talk.
