A METHOD FOR SAFELY TRANSMITTING THE SERVICE STREAM OVER THE IP NETWORK

摘要

A method for safely transmitting the service stream over the IP network includes the steps of: A .the service server sends the first request to the resource manager to request to establish a service stream path between the calling user and the called user on the carry network; B. the resource manager selects a service stream path between the first backbone network edge router where the calling user exists and the second backbone network edge router form the logical carry network; C. the resource manager sends the request information to the first and the second backbone network backbone network edge router based on the service stream path; D. the first and the second backbone network edge routers establish the stream class table including the said service stream path respectively and forward the service stream according to the stream class table to the corresponding stream path in the logical carry network. This can realize the logical separation and the class transmission of the service stream and ensure the security when the telecommunication service carried in the IP network.
