Cooperative traffic management for co-existing overlays

The overlay network has been widely deployed by Service Providers to provide services. Since there are multiple SPs built upon the same ISP, their overlays are co-existing and may interfere with each other. The selfishness of overlay may lead to sub-optimal performance and traffic arrangement dilemma for overlays. To optimize the performances of overlays and maximize the benefit of SPs, we proposed a cooperative traffic management framework. Several models are applied to analyze and solve the overlay routing problem, the revenue allocation problem, and the coalition formation problem in the framework. Simulations are performed to evaluate the framework.
