Research on Finite-timescale Bandwidth Provisioning for Aggregated Traffic
有限尺度汇聚流带宽规划研究

Because of the characteristics of Internet best-effort and the complexity of the access network structure, it is difficult to meet the quality of services such as long range depend real-time interaction streaming media for Next Generation Broadcasting (NGB) network. According to statistical multiplexing of the quality of service guarantee policy framework, availability of finite-timescale bandwidth provisioning for streaming media traffic with self-similarity is proved. Furthermore, depending on the Poisson Pareto burst process traffic model, a bandwidth provisioning method is proposed based on traffic roughness that describes the burst of the traffic. And it is analyzed that the self-similarity of the aggregated traffic is dominated by the sub-traffic. So the burst can be reduced by the large scale aggregation of the traffic, and the finite-timescale bandwidth provisioning is critical for the deployment of Next Generation Broadcasting (NGB) network.
