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

23. 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

24. 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

25. 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
