Method of simulating SNMP network element and performing network management system test with the network element

Abstract

A simulation SNMP network element includes the configuration parameter module, the agent module, the sequence traps generation module and the random traps generation module; using the network element to process network management system test method: when the simulation network element startup, according to the configuration file, initializing; setting simulation agents number, the listening port number when each agent startup, and parameters and rules to simulated send alarm; at the different port number, activating multiple SNMP monitor threads; when SNMP monitoring thread receives SNMP request information, it returns the command execution result to the background network manager; using sequence order to submit Trap message to the background network manager, to debug the background network management alarm function; using random sending mode to submit the Trap message to the background network manager, to simulate the real warning handling process of the foreground network element. The invention can use simulation large-scale network elements in the laboratory to achieve the pressure and performance testing of the background network manager, and also reduce the time waiting for co-debug of the background network management.

Description

technical field [0001] The invention relates to a telecommunication network management system in the field of telecommunication, and in particular to a method for simulating SNMP network elements to test the network management system. Background technique [0002] TMN stipulates that the field of network management includes five major functions: 1. Configuration management; 2. Alarm management; 3. Performance management; 4. Security management; 5. Account management. At present, the commonly used standard communication protocols in the network management system are mainly divided into SNMP and CMIP. The SNMP protocol, in particular, has gradually become a de facto standard protocol for network management due to its short development cycle and simple protocol implementation. [0003] The SNMP protocol network management system adopts the Manager (management) / Agent (agent) architecture, in which the background network manager is the Manager, and the front-end network element i...

Problems solved by technology

[0008] However, the currently developed simulated network elements generally have the following shortcomings. They can only be used for MIB interface debugging, that is, they can only passively receive SNMP operation messages sent by the background network management system, and then return the command execution status, but cannot simulate the front-end network element to actively report. Trap messages, even if the trap message reporting process can be simulated, can only be sent periodically according to the rules configured by the user, while real network elements send alarm and alarm recovery messages randomly, so the alarm processing process of real network elements cannot be simulated

[0009] The simulated network element currently developed still has a relatively big defect. Since the front-end network element is uniquely identified by the IP address, only one front-end network element device can be simulated on a computer, but the background network management needs to manage a large number of front-end network elements. equipment for stress testing, then as many computers as the number of front-end network elements need to be simulated, which is generally unsatisfactory in the actual test environment
