Automatic exchange optical network and traditional network interconnecting method

Abstract

The invention discloses an interconnection method of automatic exchange optical network and traditional network, which comprises the following steps: 1. Connections are established on the traditional network by a management plane, one or more connections of the traditional network form virtual link in the automatic exchange optical network, and then the configured virtual link information is distributed in the automatic exchange optical network; wherein, the virtual link information comprises the resource label corresponding relationship at two ends of the virtual link; 2. The automatic exchange optical network utilizes the configured virtual link information for connection recreation or rerouting. Compared with the prior interconnection method of the ASON network and traditional network, the ASON network has the advantages of using the traditional network resource for business establishment and rerouting, and improving the intelligence of network business scheduling.

Description

technical field [0001] The invention relates to the field of transmission network, in particular to a method for interconnecting an Automatic Switched Optical Network (ASON for short) and a traditional network. Background technique [0002] Optical network, such as OTN (Optical Transmission Network, Optical Transport Network), WDM (Wavelength-Division Multiplexing, Wavelength Division Multiplexing), SDH (Synchronous Digital Hierarchy, Synchronous Digital Series) or SONET (Synchronous Optical Network, Synchronous Optical Network) transport network , has been widely used in the field of telecommunications. ASON is a research hotspot in the field of optical network in recent years. It completes functions such as automatic establishment and automatic recovery of service connections by setting a special control plane (Control Plane, CP for short). [0003] In the traditional network before ASON, the establishment and recovery of its services were controlled through the Manageme...

Problems solved by technology

[0005] Although the general method mentioned above can complete the establishment of the connection, the route between the networks cannot be automatically determined, and the intervention of the network management personnel is required, and the automatic creation of the connection is not intelligent enough.

In addition, the above method cannot meet the needs of service restoration and rerouting
