We have studied the delay-related rate oscillation within Diffserv. The rate oscillation can come from large round trip latency. Enforcing low feedback overhead can also cause the rate oscillation. The Selective Attenuation Feedback via Estimation (SAFE) is proposed to reduce the oscillation while maintaining fast response to network dynamics. SAFE has no per-flow accounting. Furthermore, the hashing...
The ever-growing usage of the Internet and the popularity of multimedia applications result in a need to extend its simple best-effort service model. Differentiated Services (Diffserv) is a promising architecture for supporting a wide range of network services over the Internet. While scalable and flexible, Diffserv must still overcome several challenges including providing per-flow service guarantees...
