METHOD AND APPARATUS FOR COMPUTING A SERVICE PATH

摘要

A calculating method and apparatus of service path. The method comprises the steps of: obtaining the traffic engineering links information carrying the links attribute identifications issued in a network client layer; selecting a traffic engineering link corresponding to a link attribute identification meeting the service requirement as the path calculating resource of the network client layer according to the service requirement and the traffic engineering link information; calculating the service path according to the selected path resource. It can resolve the problems such as the lower success rate of service establish or the longer time of the service restoration led by the existence of the virtual links and so on, and realize the fair use of the resources by using the method.
