Communication adaptation layer system and method for obtaining the network element information

Abstract

This invention relates to the adaptation layer communications system, including the use implementation of the management body of Distributed Bus. This invention relates to a methods to get network element information, including the following steps: external service module based on the implementation of the above mentioned reference to the implementation of sending information access request, the period of implementation of the request under the access to information external to the network elements described in the implementation of access to information operations, and from external referred access to the network element to the network element information back to the services described in external modules. Through this invention will be distributed bus communication adaptation layer system is divided into relatively independent of the management and implementation of the deployment can be deployed to the implementation of the service module and outside the management of other equipment, which has a good Distributed identity.

Description

technical field [0001] The present invention relates to the field of network technology based on the framework of the Telecom Management Network (TMN), in particular to a communication adaptation layer system for a network management system to communicate with network elements and acquire network element information, and an acquisition method. Background technique [0002] Various hardware devices and software systems are deployed in the TMN, and the network management system can manage these hardware devices and software systems as network elements in a unified manner. When the network management system supports some services, it may need to communicate with network elements through a communication adaptation layer (Telecom Adapter Layer, TAL for short), and obtain specific information of the network elements. FIG. 1 is a schematic diagram of the layers of the TAL in the TMN in the prior art, where the service module can be a performance service module, a fault service modu...

Problems solved by technology

When the number of network elements accessed by the network management server under this centralized deployment reaches the limit, capacity expansion is required. However, due to the defects of centralized expansion, it is only possible to use a new network management server with higher configuration and replace the original network management server. Only when the data in the server is moved out can normal management be carried out. Obviously, this method requires a lot of work, and the original network management server cannot be reused.

[0004] This centralized deployment has another disadvantage: when the network segment where the network management server is located is not in the same network segment as the network element it manages, if a firewall policy is adopted in the network segment of the network element, the network management server cannot The address information of the firewall cannot access the network elements it manages, so it is impossible to manage the network elements inside the firewall

The TAL deployed in this way cannot access the network elements in the firewall it manages.
