Scalable Internet QoS Architecture

Synopsis

This project investigates QoS provisioning architectures for wide area networks such as the Internet where users are selfish and possess diverse QoS requirements. The two principal challenges are scalability and QoS-sensitivity - i.e., above and beyond differentiated services - both of which are required to facilitate a working architecture for the next generation Internet. We have constructed such an architecture - SBS (Stratified Best-effort Service) - which will be implemented and benchmarked on the Purdue Infobahn, a private configurable WAN testbed which is in the process of being built.

Goal

New solutions to effective QoS provision on the Internet. Some of the issues include:

Noncooperative network environment with selfish applications or users.
Scalable, QoS-sensitive services.
Stratified best-effort QoS provision without resource reservation.
Provision of stable, adaptive services.

Projects

Analysis of noncooperative QoS provision games.
Design/analysis/implementation of LAN-scale systems.
Design/analysis/implementation of WAN-scale (many-switch) systems.
Game-theoretic analysis of congestion control protocols.
