  • Method and apparatus for routes separation in ASON services
    Patent number: 9148361
    Abstract: The present invention discloses a method and an apparatus for routes separation in ASON services, wherein the method comprises: calculating a route between each of different calls or each of different services of a same call in an automatic switched optical network (ASON); wherein if there are enough network resources, then set the routes of the respective services to be independent from each other; and if there are not enough resources, then set the routes of the respective services to be partially overlapped or completely overlapped. According to the technical solution provided by the present invention, the problem in relevant art that the routes carrying each of the services cannot be sufficiently separated or the network resources cannot be sufficiently used is solved, thus not only multiple services using the same path can be avoided but also the situation that routes cannot be found while there are enough resources can be avoided.
