Abstract： |
The present invention belongs to a router forwarding technology of the Internet network layer, which is characterized in that simple service quality routing priority protocol packet is transmitted to adjacent routers according to a routing link state advertisement and the routing link state advertisement expands outside the domain, and on the basis on a way of combination of cycle and trigger, and through an interactive routing link state advertisement LSA, each router maintains the two-way service quality measurement Qos of the network topology structure and the links connected with all interfaces of each router inside the domain, to calculate the best rout from the local router to the network address within the domain, and meanwhile, to calculate the best rout to the network address prefixes and maintain the routing table of the service quality routing according to an expansion routing link state advertisement generated by a border router, and in combination with the best rout from the local router to the border router. Thus the present invention realizes the expansion of service quality that the priority of the shortest route is opened. |
