Summary of the invention

The object of this invention is to provide a kind of method of Optical Transmission Network OTN interior lines resource and outside line resource associations.

The object of the invention is to realize in the following manner, for telecom operators' full-service resource unified management, omnidistance through business demand, a kind of method of Optical Transmission Network OTN interior lines resource and outside line resource associations is provided, for service-oriented, curstomer-oriented under full-service end to end resource topology theoretical foundation and implementation are provided.

Implementation of the present invention is as follows:

In view of the Relationship Comparison difficulty directly setting up light path-circuit, the present invention, by intermediary resources model, by setting up the progressive incidence relation of " light path-physical segment-time slot section-passage-circuit ", finally sets up associating of light path and circuit.The model schematic of the bearing relation from optical fiber to circuit is as follows:

Light path-> physical segment-> high-order time slot section-> low order time slot section-> passage-> circuit.

Implementation of the present invention realizes according to the following steps:

1) by the resource model by section Segment, the relation of light path and physical segment is first set up;

2) by the relation of light path and physical segment, find the time slot section (as 155M or 2M) that this physical segment carries, form the incidence relation of light path and time slot section;

3) find and step 2 in circuit correlation table) record that the time limit section that obtains matches, obtain passage ID wherein, with step 2) obtain light path ID and be associated, like this, just establish the association of light path-passage;

4) enquiry circuit correlation table, find and step 3) record of channels be in accordance that obtains, obtain circuit I D wherein, and with step 3) obtain light path ID and be associated, like this, just establish the association of circuit-light path, also just Optical Transmission Network OTN interior lines resource and outside line resource are finally associated.

The method of a kind of Optical Transmission Network OTN interior lines resource of the present invention and outside line resource associations, has following characteristics:

1) implementation method is simple: by setting up the association of " circuit-light path ", thus realize the association of interior lines resource-outside line resource;

2) thinking is distinct, and algorithm is efficient: start with from light path, by setting up the progressive incidence relation of " light path-physical segment-time slot section-passage-circuit ", finally sets up associating of light path and circuit.

Using value of the present invention and beneficial effect are: a kind of method providing Optical Transmission Network OTN interior lines resource and outside line resource associations, " circuit-light path " incidence relation set up by this method, the through of Internet resources territory transmission interior and exterior lines resource can be realized, thus effectively eliminate transmission interior lines, outside line resource isolates management, there is the defect of tomography, for resource under full-service United Dispatching and management, whole process is through provides feasible implementation.

Embodiment

With reference to Figure of description, method of the present invention is described in detail below.

The method of a kind of Optical Transmission Network OTN interior lines resource of the present invention and outside line resource associations, its structure has been described in detail technical scheme of the present invention by summary of the invention, is described further below in conjunction with accompanying drawing and concrete enforcement.

Specific implementation step is as follows:

1) according to the resource data of resource system management, set up the relation table OpticalPath-Segment of light path-physical segment, its data structure is as shown in table 1 below:
