Method and system for multi-domain heterogeneous interconnected network management based on PCE (path computation element)

Abstract

The invention provides a method and a system for multi-domain heterogeneous interconnected network management based on a PCE (path computation element). The system comprises a message management module, a processing module, a northbound network management interface and a user interface, and is characterized in that the message management module is used for receiving a message which is from bottom layer equipment and reported by the PCE, parsing the message, extracting a message header according to a format and judging the message type; the processing module is used for carrying out corresponding processing on the message according to a judgment result so as to acquire a first processing result and store the first processing result; the northbound network management interface is used for receiving a request sent by an upper-layer network manager, parsing the request, carrying out processing on the request through a network management system, reporting the states of the bottom layer equipment and the PCE and a request processing result to the upper-layer network manager; the user interface is used for receiving a request for sending the message; the processing module is further used for carrying out corresponding processing according to attributes of the request so as to acquire a second processing result; and the message management module is further used for processing the second processing result so as to generate information with a uniform format, and sending the information to the bottom layer equipment and the PCE. The system provided by the invention has the advantages of comprehensiveness, efficiency and novelty.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a PCE-based multi-domain heterogeneous Internet management method and system. Background technique [0002] Multi-domain heterogeneous optical network means that in the network, different manufacturers, different devices and different transmission mechanisms respectively constitute multiple domains, and each domain is connected by inter-domain links. Different vendors have their own element management systems (EMS) to manage and configure their respective underlying devices, but the EMS message formats of different vendors are different, and the devices they control are also different, so it is impossible to realize the unification of each domain Control and interconnection. With the development of distributed path computation element (pathcomputation element, PCE) technology, the problem of path computation in the domain where PCE is located has been well solved....

AI Technical Summary

Problems solved by technology

The network device management system can obtain device configuration, device fault information, etc. from the bottom layer, but cannot know the business running on the device

The network business management system can obtain relevant business information and implement functions such as business control and establishment. However, when a business failure occurs, it cannot obtain equipment operating status in time, which does not help much in troubleshooting. Therefore, equipment management and business management are disconnected from each other. of
