Abstract: Link bandwidth resource planning is both the foundation of the implementation of the large scale real-time streaming media applications and the precondition of network deployment in the broadband access environment.This paper proposes a link bandwidth planning method with Poisson Pareto burst process traffic model.And this new method can resolve the planning problem with the traffic information of only a small set of timescales.The method is realized in the way of counting local cache information.The validity and the performances of the method, including the space complexity and computational complexity, are investigated in the paper.An optimal network deployment scheme is proposed.This scheme can meet the requirement of QoS and is easy to be implemented.
