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 the authors' previous work, they 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, they are able to deliver timely information to routers while retaining a meaningful estimate of the original statistical value.
