Executive Summary

Quality of Service (QoS) is important in multi-user residential networks that share a common bandwidth-constrained Internet connection. A limited upstream bandwidth can become a bottleneck and the performance of delay-sensitive applications - such as VoIP and online games - can degrade significantly when latency is introduced by other traffic flows. Current residential router QoS support must be manually configured and set up is difficult for the average home user. The DIFFUSE (DIstributed Firewall and Flow-shaper Using Statistical Evidence) architecture has been developed to provide automated IP traffic classification and treatment based on statistical flow properties.
