Method for configuring path route at carrying network resource supervisor

Abstract

This invention discloses a method for configurating routes and paths on the carrying network resource manager including 1, pre-configurating route and path information necessary for carrying the network resource manager. 2, After the manger receives the request or resource response, it selects suitable routes and paths from the routes and path information configurated in step 1.

Description

technical field [0001] The invention relates to a differentiated service model (Diff-serv, DifferentiatedService) technology with an independent bearer layer, in particular to a method for configuring a routing path on a bearer network resource manager. Background technique [0002] As the scale of the Internet (Internet) continues to increase, various Quality of Service (QoS, Quality of Service) technologies emerge as the times require. Therefore, the Internet Engineering Task Force (IETF, Internet Engineering Task Force) has suggested many service models and mechanisms to meet the requirements of QoS. At present, the industry generally recognizes that the integrated service model (Int-Serv, Integrated Service) is used at the access and edge of the network, and the differentiated service model (Diff-serv, Differentiated Service) is used at the core of the network. The DiffServ model only sets priority levels to ensure QoS measures. Although this QoS measure has the charact...

In this solution, the LSP information is configured on the QoS server. From the LSP information, the QoS server obtains the LSP information suitable for the customer's call service, and selects the LSP for the customer's call service and reserves bandwidth resources on the LSP. However, in this In this solution, the LSP information configured on the QoS server is divided into various levels according to the priority. The QoS server selects high-priority LSP information for high-priority service requests, and requests low-priority LSP information for low-priority services. For resource information, if the volume of low-priority service requests is large and the volume of high-priority service requests is small, it will cause network congestion for low-priority services and idle bandwidth for high-priority services. Therefore, using this The scheme selection route is relatively rigid, not flexible enough, and inefficient

In addition, the Rich Qos solution is a relatively complex bearer network with a large number of routers; at the same time, the QoS server and the policy server notify the edge routers to use the explicit routing Multi-Protocol Label Switching (MPLS) LSP establishment technology to establish an end-to-end LSP. This model has poor scalability and limited network scale
