Abstract

The invention discloses a routing constraint precomputation method and system based on control plane resources, and relates to the technical field of communication equipment management, and the methodcomprises the steps: obtaining the resource state information of all ASON nodes in a network, and building a resource state data object; obtaining whole network TE link information, and establishinga TE link data object; setting a circuit level, a rate and source and sink port information which need to be created; performing routing constraint precomputation according to the resource state dataobject, the TE link data object and the circuit level, rate and source sink port information to be created; and creating an SPC service conforming to the routing constraint precomputation result according to the routing constraint precomputation result.

Description

technical field [0001] The invention relates to the technical field of communication equipment management, in particular to a method and system for precomputing routing constraints based on control plane resources. Background technique [0002] With the development of telecommunication networks and the improvement of user demands, traditional OTN (Optical Transport Network, Optical Transport Network) networks have gradually exposed some problems: complex service configuration, low bandwidth utilization, single protection mode, etc. In order to effectively solve the above problems, ASON (Automatically Switched Optical Network, Automatically Switched Optical Network) came into being. It introduces signaling into the transmission network, and enhances network connection management and fault recovery capabilities by increasing the control plane. It supports end-to-end service configuration and multiple service protection forms; it can also provide different protection types acc...
