Embodiment Construction

[0040] The following combination figure 1 , illustrating the flow of a preferred embodiment of the method of the present invention.

[0041] In step S010, the configuration information of all protection systems in the transmission network is saved, including the protection modes of the protection systems and the network elements forming the protection systems. These configuration information are stored in the existing transmission network management system.

[0042] The user can also add the cost value set for the protection channel in each protection system in the configuration information. The overhead value represents the cost of the service passing through the protection channel. For example, the overhead value can be determined according to the length of the optical fiber. The longer the length, the greater the overhead. In this way, when multiple protection paths can be combined and generated, the protection path with the lowest service consumption can be selected acco...

Abstract

A protection method of transmission network, including the following steps: saves the configure information of all the protection system in the transmission network, the configure information includes the protecting channel of the protection system; the transmission network appears the operation fault of the simple protection system that can not be recovered; confirms the free protecting channel in the protection system; uses the protecting route to recover the operation transmission when some free protecting channels of the protection system form the recoverable protecting route of the protecting channel. The invention can use the redundancy source in the transmission network effectively and provide more protect for the transmitting operation in the network, by the protecting route that forms of the protecting channel belongs to some protection system to recovering the operation fault.

Description

technical field [0001] The invention relates to a transmission network, in particular to a method for protecting a transmission network. Background technique [0002] As the world moves towards an information society, in order to meet the growing demand for bandwidth, especially the expected Internet (Internet) development for network bandwidth, it is necessary to adopt new technologies and develop new network structures. The transmission network becomes the development direction of the next generation network. With the continuous changes of users and network services, the transmission network is required to provide users with economical and rapid circuit and business services, and to ensure that the business layer signals have protection capabilities in case of accidents. [0003] Transmission networks include SDH (Synchronous Digital Transmission System) and OTN (Optical Transport Network). In SDH, the protection methods used include SPRing (Shared Protection Ring), 1+1 ...
