摘要：
A novel partially observable Markov decision process (POMDP) based admission control scheme is presented for SDN-based media delivery network. The performance bottleneck of service nodes on the application layer, and the service ability limit of transmission links between nodes and users are comprehensively considered, then the POMDP is used to model the admission control process of the service system. The randomized policy is applied to optimize system performance, and the policy-gradient iteration algorithm is used to compute the optimal admission control policy. Numerical experiment illustrates the efficiency of the proposed approach.
