CHOKeD: A Fair Active Queue Management System
Fairness is the significant factor to sustain best effort delivery of network
services. Now-a-days, real-time multimedia applications have evolved largely
over the Internet. Most of multimedia services are unresponsive during network
congestion. Unresponsive traffic streams steal most network bandwidth and
starve out some other flows which are responsive during network congestion. In
the presence of these unresponsive traffic flows, protection of responsive
flows has become a major issue. Many Active Queue Management (AQM) based
solutions have been recommended to protect responsive traffic flows from
unresponsive ones and to ensure fairness among all traffic flows. The thesis
proposes a novel AQM scheme CHOKeD, to deliver fairness among all flows of a
congested link. It is a completely stateless approach. CHOKeD is based on
dynamic drawing factor to penalize unresponsive traffic. It successfully
protects responsive flows in the presence of unresponsive flows. CHOKeD
features such as fairness, high throughput of responsive traffic and stateless
design, are encouraging factors for its deployment over the edge as well as the
network core routers. Extensive simulations have been carried out to evaluate
its performance under real-time network scenariosComment: MS thesi
