摘要
The current best-effort Internet is adverse to deliver real media information since it is provided with an uncertain delay property in the traditional routing, flow control and retransmission. The research on the access control mechanism is more significant along with the development of the media applications. In this paper, a multi path access control scheme on cost in core packet network is proposed to make it highly scalable and robust. In which, the scheduling and routing model in core network is presented, and the link cost of core network is calculated, then the optimized route is selected in term of the minimum cost. Simulation results show that the cost provided by this access control scheme would be nearly accordant with the performance of services in the network.
