Bandwidth Management of a Future Internet Architecture

Network virtualization provides the feasibility of running multiple routing architectures on a shared physical infrastructure. This paper presents the design and evaluation of a bandwidth management algorithm which is based on traffic predictor. We generated the simulation traffic with the ARMAX/GARCH model. The basic idea of our design is that some failure in the MFP computation implies that one or more links do not have enough available capacity, which violates the linear constraints on the commodities for each link when modeling MFP. Then we present the results of performance comparisons of the predictor-integrated algorithm and the allocation algorithm only by Solving MFP. The comparisons are based on the mean packet delay, the variance of the packet delay, and the buffer requirements. Our performance tests show that predictor-integrated algorithm works better than the allocation algorithm only by Solving MFP in terms of the three metrics listed above.
