Problems solved by technology

[0009] The existing technology can only manage services with end-to-end protection functions through a single signaling method, which cannot provide services with segment protection functions manage
As shown in Figure 2, the working path (A-B-C-D-E-F-G) has segment protection, a working path no longer has a complete end-to-end protection path, but has two segment paths, that is, Segment1 (B-H-D) protects the B-C-D of the working path Part, Segment2 (C-I-J-F) protects the C-D-E-F part of the working path, and the business with segment protection cannot be managed through a single signaling method similar to end-to-end business management

Embodiment Construction

[0028] As shown in Figure 3, the service management method in the intelligent optical network provided by the present invention mainly includes the following steps: the network node receives the management request (step 302) that includes the operation object and the operation type, and creates a management request message according to the management request , and send the management request message to each node along the service working path (step 304); each node on the working path receives the management request message, and completes the corresponding management operation on the service according to the operation type ( Step 306).

[0029] For services with end-to-end protection functions, commonly used external management commands include: "Lock the protection channel", "Lock the working channel", "Force switching from master to backup", "Manual switching from master to backup", "Force switching from backup to master", "manually switch from standby to master", "freeze cur...

Abstract

The invention relates to an operational control method in intelligent light network. Network nodes receive the management request containing action-object and action-type. A manage request information is established based on the management request and is sent to each node along an operation service path. Each node on the operation service path receives the said management request information, and the corresponding management operation is performed based on the operation type. The said invention can perform the recovery operation management of outer protection for the whole connection or some subsection path and the management to the service of operator is increased.

Description

technical field [0001] The invention relates to an automatic switching optical network system, in particular to a method for managing services with segment (Segment) protection functions in Mesh networking. Background technique [0002] Traditional optical networks, such as Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy), Synchronous Optical Network (SONET, Synchronous Optical Network) and Optical Transport Network (OTN, Optical Transport Network), mainly adopt the form of self-healing ring networking, and the bandwidth utilization rate not tall. Moreover, the traditional optical network mainly adopts the method of static configuration through the network management, and the configuration is complicated and time-consuming. With the demand for multi-service, high bandwidth, high survivability, and fast connection provision, the existing network architecture and networking methods will be impacted, and the network topology will evolve from the traditional r...
