Embodiment 1

[0045] Such as image 3As shown, this embodiment provides a session process between the network management system and the managed network element device, the session process is initiated by the network management system, specifically including:

[0046] Step S301, the foreground interface of the network management system initiates a session command to the background server;

[0047] Step S302, the background server of the network management system packs the management control command and data according to the protocol requirements, and sends the obtained management data packet to the network management agent of the managed network element device;

[0048] Step S303, after the network management agent receives the management data packet, it forwards it to the corresponding module unit for processing, and packs the processing result of the module unit into a control response message and returns it to the network management system;

[0049] Step S304, the background server of th...

Embodiment 2

[0054] In order to increase session security, in this embodiment, when the network management system conducts a session with the managed network element device, the legality verification process of the managed network element device to the network management system identity is added. Since each managed network element device leaves the factory It will save the MAC address of the legitimate network management system device of this node, so the managed network element device can authenticate the network management system through the received network management message; the identity verification process can be verified based on the initial session message at the beginning of the session, of course for Increase the security of the system session, and can also be verified based on each network management message;

[0055] Such as Figure 4 As shown, this embodiment provides a session process between a network management system and a managed network element device, including the fol...

Embodiment 3

[0068] In order to prevent replay attacks, this embodiment adds a session serial number and a data packet serial number to the data packet in the session process, specifically as follows: for each session process, the sender will randomly generate different session serial numbers, if the same If there are multiple data packets interacting in the session process, the sequence numbers of the data packets are used for identification. The receiver can perform anti-replay processing according to this field. If two consecutive (or more) messages with the same session sequence number and packet sequence number are received, the same message will be discarded and an alarm will be generated.

[0069] Such as Figure 5 As shown, the embodiment of the present invention provides a session flow between the network management system and the managed network element equipment. In this session flow, the session sequence number is generated by the network management system, and the network mana...

Abstract

The invention discloses a method for managing network elements by a network management system. The method comprises the following steps: the network management system sends a management data packet to the network elements, wherein, the management data packet contains module units, management items and management content fields which need to be managed in the network elements; and the network elements receive and send the management data packet to the corresponding module units in the network elements for processing, and take the processing results as response information to return to the network management system. By adopting the method, the data packet format defined by an SNMP (simple network management protocol) is extended; and by adding information of the network elements such as the module units, the management items, the management content and the like to the data fields, when the network management system allocates the network elements, a plurality of interactive processes between the network management system and the managed network element equipment are effectively simplified, the communication traffic between the network management system and the managed network element equipment is reduced, and the operating efficiency for network management is improved when the network management system carries out network element configuration.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for managing network elements by a network management system. Background technique [0002] SNMP (Simple Network Management Protocol, Simple Network Management Protocol) is one of the most widely used network management protocols at present. It provides a method for monitoring and managing various device resources in a computer network. It has been widely used and become the de facto standard of network management. [0003] However, the syntax definition of the traditional SNMP management information base (MIB) is relatively simple, and can only represent simple data structures; the management operations supported by the SNMP protocol are relatively single, and it is difficult to support complex addition and deletion operations on managed object instances, which is not suitable Transmits management information with a large amount of data. Using the SNMP protocol...
