21. Network Group • Parmesh Ramanathan • Wireline and Wireless Networks • Rajeev Agrawal (on leave) • Communication Networks • Yu Hen Hu (on leave) • DSP, VLSI and Multimedia

22. Parmesh Ramanathan Research philosophy: • Premise: the same-service-for-all paradigm of today’s Internet not adequate for emerging applications • Next Generation Internet (NGI) must support quality of service (QoS) differentiation • Goal: Develop techniques for QoS differentiation in NGI • techniques consistent with Internet’s philosophy as opposed to telephone network’s philosophy

23. Parmesh Ramanathan Research projects: Wireline • Architecture for relative differentiation in NGI • develop router mechanisms and user adaptation strategies • mainly algorithm development and theoretical analysis • validation through large scale simulations • Prototyping QoS differentiation techniques • network testbed with several PCs and four Gigabit switches • compare the implementation and performance overheads of our solutions

24. Parmesh Ramanathan Research Topics: Wireless • QoS support in high data rate (45 Mbps) wireless networks • collaborative project with other faculty members • investigate all key aspects of a wireless network in an integrated fashion (antennas, receiver structures, communication subsystems, networking issues) • Packet data services in third generation cellular networks • develop solutions for QoS support within framework of IMT-2000 • prototype solutions on a wireless network testbed
