Problems solved by technology

All these operations may affect or interrupt telecommunication services, thus bringing huge disasters to the telecommunication network
[0005] At present, the main way to solve this problem is to use SNMP V3, and use the security mechanism supported by SNMP V3 to protect the managed telecommunication equipment from attacks, but there are the following problems in the use of SNMP V3: (1) SNMP V3 is too complicated, it is no longer It is a "simple" network management protocol, which increases the difficulty of implementation; (2) At present, many telecommunication equipment and SNMP development tools do not support SNMP V3

Embodiment Construction

[0051] Below, refer to Figure 2 to Figure 7 The SNMP-based network management method of the present invention will be described.

[0052] In the SNMP-based network management method of the present invention, network management is performed between the NMS and network elements based on SNMP. The main flow of the method includes:

[0053] NMS starts and initializes;

[0054] The NMS detects the communication status and key status of the network element to determine whether it needs to synchronize the key with the network element;

[0055] The NMS generates an SNMP Get request for querying the current information of the network element and sends it to the network element, and the network element returns an SNMP response containing the current information of the queried network element;

[0056] The NMS generates an SNMP Set request for controlling / configuring the network element, encrypts the generated SNMP Set and sends it to the network element, and the network element retu...

Abstract

This invention puts forward a high safety network management method based on SNMP including the following steps: a, NMS starts up and carries out initialization, b, the NMS tests the communication state of NE and the state of cryptographic key to determine if it's necessary to carry out cryptographic key synchronization with the NE, c, the NMS generates the SNMP Get request for enquiring the current information of the NE and sends it to the NE, which feeds back the SNMP response containing the required current information of the NE, d, the NMS generates the SNMP Set requirement for controlling / configuring NE to be ciphered and sent to the NE, which feeds back the SNMP response containing the control / configuration result.

Description

technical field [0001] The present invention relates to the security management of the communication network, in particular to a network management method based on SNMP (Simple Network Management Protocol: Simple Network Management Protocol) in the communication network management. Background technique [0002] figure 1 is a schematic diagram representing the network management structure. exist figure 1 SNMP-based network management is performed between the NMS and the managed network (network element), wherein the NMS (Network Management System, network management system) includes an NMS application layer and an NMS communication layer. In addition, SNMP is a management protocol widely used in the field of telecommunications network management. It provides a method for collecting network management information from network devices and controlling / configuring network settings. At the same time, SNMP also reports problems and issues to NMS for devices. Errors provide a way...
