Heterogeneous flow congestion control

Abstract:

Switch fabric in routers require tight characteristics in term of packet loss, fairness in bandwidth allocation and low latency for high-priority traffic. Such attributes have been resolved using specialized switch devices, but with the emergence of Data Center Bridging, the possibility of using commodity Ethernet switches to build switch fabric in routers is considered. Systems and methods are provided for estimating congestion associated with a network path in accordance with the variation in average delay experienced by samples of packets.
