Abstract
In communication networks with policy-based Transport Control on-Demand (TCoD) function, the transport control policies play a great impact on the network effectiveness. To evaluate and optimize the transport policies in communication network, a policy-based TCoD network model is given and a comprehensive evaluation index system of the network effectiveness is put forward from both network application and handling mechanism perspectives. A TCoD network prototype system based on Asynchronous Transfer Mode/Multi-Protocol Label Switching (ATM/MPLS) is introduced and some experiments are performed on it. The prototype system is evaluated and analyzed with the comprehensive evaluation index system. The results show that the index system can be used to judge whether the communication network can meet the application requirements or not, and can provide references for the optimization of the transport policies so as to improve the communication network effectiveness.
