Hamilton Institute Workshop on Congestion Control

27th and 28th September 2005

The Hamilton Institute held a workshop to discuss outstanding issues in network congestion control in September 2005. Topics for discussion will included buffer sizing, AQM and design of congestion avoidance techniques. A poster for the workshop is available.

The workshop was held in Physics and Chemistry Theatre (PCT) in the Science Building on NUIM's North Campus. A map of the campus is available. For further details please contact David Malone.

The program was as follows.
