Abstract
Our goal is to design a low-loss, low-delay service for elastic users in the
Internet using Active Queue Management (AQM) schemes. AQM schemes in
Internet routers provide congestion information to end sources by
marking or dropping packets. We will propose and analyze a class of AQM
schemes that, in conjunction with TCP and other congestion
controllers, allow the router to achieve a high level of utilization
while keeping the queue length small. We will then propose a specific
AQM scheme called the Adaptive Virtual Queue Algorithm that can be
easily implemented in routers and performs well compared to other AQM
schemes. We will discuss its implementation and its performance
relative to other AQM schemes. We then proceed to address the issue of
providing service differentiation in the Internet. We will propose a
Class based version of the AVQ algorithm that achieves low-delay for all
users while maintaining the service guarantees of higher priority
traffic.
