Embodiment Construction

[0054] The core idea of ​​the present invention is: in the automatic switching optical network, the network entry node of the network connection service determines and saves the routing information of the recovery path; when the working path is established successfully, the network management system controls the resource reservation processing of the recovery path; when the working path After the interruption, the network entry node of the network connection server initiates the establishment process of the restoration path according to the saved routing information of the restoration path and utilizes the reserved resources, and switches the service of the working path to the restoration path for transmission.

[0055] In order to have a further understanding of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] The specific embodiment of the present invention is as figure 1 shown, including t...

Abstract

The invention discloses a sharing grid net recovery accomplish method, which is characterized by the following: the network entrance node of network concatenation service ascertains path information of recovery path and keeps the information; the pipe network system controls resource preformed processing after the duty route successes to build; when the working course is interrupted, the network entrance node of network concatenation server uses prepared resource to initiate build procedure of recovery route according to path information of reserved recovery route; the work route business is changed into recovery route to transmit. The invention simplifies the technical project.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing the restoration of a shared grid network. Background technique [0002] Optical transport networks, including SDH (Synchronous Digital Hierarchy, Synchronous Digital System), SONET (Synchronous Optical Network, Synchronous Optical Network) and OTN (Optical Transport Network, Optical Transport Network), are traditionally designed to transmit voice services, data The rapid development of business makes it account for the continuous increase of the proportion of the transmission traffic of the existing optical network, the demand for the bandwidth of the transmission network continues to increase, and the requirement for service provision time is getting shorter and shorter. This has impacted the existing network architecture and networking form. In order to meet the needs of data service transmission, the network topology needs to evolve from th...
