P2P service establishing method

Abstract

The invention discloses an end-to-end service building method, wherein, if two end points of the end-to-end service belong to the same EMS, NMS directly triggers the minimal weight route between the computing end point net elements of the EMS; if the two end points belong to different EMS, the NMS triggers the minimal weight route of EMS layer between the EMS border net elements of EMS computing end point net elements belonging to the end point net elements, triggers other EMS to compute minimal weight route of EMS layer between the EMS border net elements of EMS, afterwards, the minimal weight route of the NMS layer is computed by NMS, thereby realizing computation of the minimal weight route between two end point net elements of end-to-end service. The end-to-end service building method disclosed in the invention advances building efficiency of service and implement is simple.

Description

technical field [0001] The invention relates to the service management technology of the communication service, in particular to an end-to-end service creation method. Background technique [0002] With the continuous expansion and deepening of people's communication needs, the scale of the communication network is getting larger and larger, and the number of operating equipment included in the network is also increasing. In this case, it becomes more difficult for operators to open services across many network elements. [0003] At present, the hierarchical deployment method is generally used in the network management system. The system that directly manages regional equipment is called the network element management system (EMS), and the upper-level management system that manages the EMS is called the network layer management system (NMS). ). [0004] NMS provides the function of creating end-to-end services and user-selectable routing constraints. NMS directly calculate...

Problems solved by technology

However, the linear increase in the performance of hardware devices cannot well solve the problem of exponentially increasing computing power brought about by network expansion.

[0007]In addition, the expansion of the network has reduced the operator's ability to understand and control the network, which further strengthens the dependence on the network management system in service provisioning and maintenance. The NMS routing algorithm has weak concurrency and poor performance, thus forming an insoluble contradiction
