3、a operators. As the two-way transformation of cable television network and the implementation of next generation broadcast networks strategy continues, it is urgent for cable operators to build a unified service platform

4、 to open the service abilities of the edge of the access network to support the delivery of services after triple nework convergence and to ensure that services can be managed and controlled. Under the support of the Nat

6、rm. In particular, we focus on the related technologies about the resource control at the edge of the access network. The main contributions of this dissertation can be summarized as follows: 1. A new resource management

7、 method based on revenue mechanism is proposed. First, we analyze the behaviors of four typical services in television networks and obtain their revenue functions. For non-cross-domain environment, we use a greedy algori
