Network management system of implementing remote browse network element MIB node

Abstract

The invention provides a network management system for implementing the remote browsing of a network element MIB mode. In a browser / server-supported SNMP network management system, based on the AJAXWeb technique, the engines of a Web server and a MIB browser are embedded inside a network management server, so that a service engineer can remotely log in the Web server and directly select the network element from the MIB browser to initiate a query or set up a command; and an asynchronous http request is constructed by an AJAX technical module and sent to the Web server inside the network management server. Therefore, the invention realizes the remote access, even the setup of current value of the related MIB node in the remote field network element, and implements the real-time on-line state diagnosis and analysis.

Description

technical field [0001] The invention belongs to the technical field of network management, in particular to a network management system for performing MIB query or setting on remote network element nodes. Background technique [0002] After the network management system is deployed to the site, it often brings some difficult problems to the site engineers due to the complexity of the local actual situation. These problems often require remote support and assistance from more professional maintenance engineers who are familiar with network element communication interfaces. In a network management system that uses SNMP as a communication protocol with network elements, professional maintenance engineers often use MIB browsers to check the current status values ​​of related MIB nodes for network elements that have problems, so as to perform diagnostic analysis and identify the problem. However, the SNMP protocol is based on the UDP protocol. The premise of using the MIB Brows...

Problems solved by technology

[0007] In the above three cases, direct use of UDP-based SNMP protocol to access on-site network elements requires special configuration on the firewall to allow UDP packets to "come and go" freely and bidirectionally connect, which is difficult and will also weaken The security of the on-site network; the second is that the UDP protocol is unreliable. Remote UDP access needs to go through various routing devices in the intermediate network. In addition, due to the weak security mechanism of the SNMP protocol itself, the on-site network management system will customize the SNMP protocol used by it, and carry it on the encrypted communication protocol or encrypted channel. If the third-party standard is used directly It is impossible to read and write the MIB node data of network elements with the MIB browser
