Problems solved by technology

[0006] At present, there is no unified standard for switching judgments in the industry. Users do not have a standard to judge how long to switch after a problem occurs in the gateway; after the interruption, the common problem is that switching is frequent on the network management system, and it cannot be accessed through the man-machine interface (such as GUI). ) to control which gateway the non-gateway network elements go through, resulting in data congestion and other problems, causing problems such as alarms not coming up

Embodiment Construction

[0025] Configure the gateway NEs that are not gateway NEs as gateway NE A, gateway NE B, etc., and gateway NE A is the primary gateway NE, and gateway NE A is the standby gateway NE. At the beginning of the configuration, let the main gateway be the current communication gateway, and the communication group diagram is shown in Figure 2.

[0026] After the abnormality of gateway NE A causes the communication between the non-gateway NE and the NMS to be interrupted, the NMS will perform the switchover according to the following methods:

[0027] 1. The non-gateway NE does not need to communicate with the NMS after the NMS is created, and does not perform switching.

[0028] 2. After the NMS is created, the non-gateway NE needs to communicate with the NMS (for example, in the pre-configured state), and decide whether to switch by judging that the NMS receives the handshake packet from the non-gateway NE; In the case of success (that is, the communication is normal), the detectio...

Abstract

The invention discloses a gateway and a network element switching method, and relates to the communication field in order to solve the problems, such as, after the interruption between a network management and a non-gateway network element, the switching in the network management is relatively frequent, and a man-machine interface can not be used for controlling a gateway which the non-gateway network element passes, which causes the data jam and the failure of reporting the alarm. If the network management and the non-gateway network element successfully construct a link and no abnormal interruption appears in the process, and a handshake bag of the non-gateway network element is received within N cycles which are set time intervals, then the gateway network element which the non-gateway network element passes is switched to another gateway network element; if the construction of the link is constantly unsuccessful, then interfaces are regularly distributed to be connected with the non-gateway network element, wherein, N is a natural number. The method of the invention adds a protection mechanism against the abnormal problems of the gateways, and avoids the frequent switching and the phenomenon of data jam.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for switching a gateway network element during communication between a gateway network element and a network management. Background technique [0002] During the use of 8DH (synchronized digital) equipment, users put forward requirements for gateway network elements and non-gateway network elements. It is considered that there are too many IP addresses currently allocated to the SDH equipment, occupying too many IP addresses. For non-gateway network elements, only the internal IP address needs to be used. Under this premise, we designed our set of gateway network element and non-gateway network element design solutions according to user needs and some existing practices of friends. [0003] In the communication process, the network management not only communicates directly with the network element, but also communicates with other network elements through the network elem...
