Problems solved by technology

But it is obvious that the above process is more complicated. In order to transfer the business to another path, the Notification message is sent three times.
And if the new path fails after the end node has flipped to the new path, it will cause service interruption, because although the old path is still good at this time, the service on the new path is received at the end node

Embodiment Construction

[0043] The path optimization of the service with only one service path (hereinafter referred to as ordinary service) and the path optimization of the service (hereinafter referred to as 1+1 service) protected by the main and backup paths are respectively explained below to illustrate the specific path optimization of the concept of the present invention process.

[0044] First, for common services, the path adjustment and optimization method of the present invention includes the following steps:

[0045] a) Set up a new path, form an SNCP protection group between the new path and the original path, form the service intersection of the new path, and select and receive the service on the original path;

[0046] b) The service is selectively received on the new path through SNCP switching;

[0047] c) Remove the old path.

[0048] In the following, referring to FIG. 1 to FIG. 5 , a bidirectional service is taken as an example to illustrate the path adjustment and optimization m...

Abstract

Said invention refers to service route adjusting optimistic method optimistic method to avoid generating service interruption problem. Said includes A, establishing one new route composing sub network connection protecting protection group between new route and original route, to form new route service crossing, selecting service on special route, B, dismantling original route original route.

Description

【Technical field】 [0001] The invention belongs to the technical field of optical networks, and mainly relates to a method for adjusting and optimizing service paths in optical connections. 【Background technique】 [0002] The traditional optical network is a system based on centralized management. The establishment, maintenance, and removal of optical connections in this optical network system all require manual intervention, so it cannot meet the ever-increasing, dynamic, and flexible requirements of data services. In order to solve this problem, the International Telecommunications Union (ITU-T) proposed an Automatically Switched Optical Network (ASON) architecture. This architecture adds a control plane to the traditional optical network, which implements the diffusion of network topology information and the establishment and maintenance of service paths. According to this idea, a node in an optical network first obtains the connection relationship between the node and o...
