Differentiated service survivability method based on virtual service plane

Abstract

Provided is a differentiated service survivability method based on a virtual service plane. Firstly services are divided into six classes according to a service classification method; then a logical net is built on a physical network and the virtual service plane is constructed according to quality of service (QoS) requests and topology requirements of various services on the network; obligating resources on the virtual service plane constructed according to service types and conducting instantiation on the virtual service plane; distributing resources for each service on the virtual service plane according to service flow and achieving resource dynamic adjustment on the virtual service plane; and finally designing different survivability strategies on the virtual service plane according to survivability needs of different services and providing survivability guarantees for different services. The differentiated service survivability method based on the virtual service plane can meet the QoS requests of different services, meet needs of the different services on the different services, meets survivability needs of the different services, further improve resource utilization rate of a network, and further improve survivability guarantees of the network on the different services.

Description

Technical field: [0001] The invention belongs to the field of computer networks, and mainly solves the problem of survivability of different services in an IP network, and specifically relates to a survivability method for providing differentiated services for services with different QoS requirements and topological requirements. Background technique: [0002] With the development of the IP network, some new services are constantly emerging in the IP network. These new services have different QoS requirements, but the existing IP network can only provide best-effort services and cannot guarantee the QoS requirements of the services; and streaming media The emergence of such services also has special requirements for the network topology, but the current network topology is fixed and cannot meet the different requirements of different services for the topology, that is, the existing IP network cannot meet the QoS requests of different services and the requirements for the netw...

AI Technical Summary

Problems solved by technology

[0004] Different services in an IP network have different requirements for network survivability, and different survivability strategies have different attributes. For example, a survivability strategy that can meet higher survivability requirements consumes more network resources. At the same time, IP networks cannot distinguish services Designing different survivability strategies cannot meet the survivability requirements of different services and cannot improve the resource utilization of the network, that is, the existing IP network cannot provide survivability strategies for distinguishing services
