Method for realizing SPC activation/deactivation via control plane in ASON network

Abstract

The invention discloses a method to realize the SPC activation / deactivation by a control plane in the ASON network, which can realize the creation, activation, deactivation and deletion of soft permanent connection SPC based on the control plane CP in the ASON network, the resource is pre-reserved during the creation, the transmission plane is noticed to establish the configuration of cross connection after receiving the activation instruction of the management plane MP, finally the SPC connection is established; before the deletion of SPC, the activation instruction is firstly sent out to notice the transmission place to delete the cross connection, the CP continues to reserve the pre-reserved resource, the pre-reserved resource is released after receiving the deletion instruction and the complete deletion for the SPC connection is finally realized. The invention can facilitate the operation and maintenance of the network by the operation and maintenance people, provide the restoration of the pre-calculation function and effectively improve the survival of the network; and the resource pre-reserved function can ensure the flexibility of the businesses which are provided by the operators.

Description

technical field [0001] The invention relates to connection control technology in automatic switching optical network ASON, in particular to a method for realizing soft permanent connection SPC activation / deactivation function through control plane in ASON. Background technique [0002] ASON (Automatic Switched Optical Network) is a new generation of optical transport network formulated and standardized by ITU-T, which automatically completes the switching function by introducing the control plane. ASON can be implemented based on the SDH transport network of the G.803 specification, and can also be implemented based on the optical transport network OTN of the G.872 specification. ASON includes three planes of transmission plane TP, control plane CP and management plane MP, and supports three connection modes of permanent connection PC, soft permanent connection SPC and switched connection SC. [0003] The software permanent connection SPC is a mixed and practical connection...
