Abstract:
Congestion-aware routing protocols require network statistics which are timely and as precise as possible. Consequently, there is a need to represent congestion information efficiently and in a scalable manner. Based on our previous work, we propose a routing protocol, called StepRoute, which achieves these objectives, while retaining the functionality of routing according to local and remote network conditions. By classifying congestion values into different categories, we are able to deliver timely information to routers while retaining a meaningful estimate of the original statistical value. We compare our results with our previous work (MultiRoute) as well as shortest path only routing. We show that our new variant outperforms both shortest path and MultiRoute in terms of throughput. The protocol itself is media independent, but for test purposes we have employed Ethernet.
