Description

The processing method of batch MIB

Technical field

The present invention relates to network management, be specifically related to the in batches processing method of MIB.

Background technology

Along with the high speed development of the Internet and telecommunications industry, the disparate networks communication equipment extensively covers each place, has formed numerous catenets.Catenet comprises multiple network equipment, integrating multi network operating system, the application service of operation multiple network.In order to guarantee the efficient operation of above-mentioned large-scale network system, need to build one to network operation situation monitor, to the network management system that the whole network operation conditions is controlled, the operation conditions of whole network system is monitored and is managed.

Present network management system all is that Simple Network Management Protocol (SNMP, Simple NetworkManagement Protocol) manages remote network equipment.Network management based on SNMP comprises two parts: 1) network management system, the functions such as system security management, Topology Management, device configuration management, fault management, performance management, log management, system management mainly are provided, accept user operation, to managed device carry out associative operation and the result by being reflected to user interface; 2) managed device, i.e. network element is such as router, access server, switch, bridge, HUB, main frame or printer etc., network element is provided with the SNMP agency, sets up the management information bank MIB of this network element, and the response to network management system is for the operational order of MIB;

The communication process that traditional NMS is unified between the managed device is as described below:

L10, network management system directly are encapsulated in mib information in the SNMP request message and send to managed device when certain managed device is managed, and wait for its response.

L20, managed device therefrom directly take out mib information after the SNMP request message that network management system is sent, then the SNMP response message is returned to network management system.

L30, network management system parse the MIB response message, and process accordingly according to this information after receiving the SNMP response message that returns, thereby finish corresponding interface display or operation.

This shows traditional network management system and be directly in the SNMP message, to encapsulate mib information in fact by the supervisory communications between the pipe.But, along with the complexity of the network equipment is more and more higher, the function that provides is more and more, integrated circuit board quantity and interface quantity are also more and more, particularly along with the network flattening, some managed device not only will be realized the management function of self, also has simultaneously the function that topology is collected, managed other a large amount of network elements concurrently, such as EPON OLT, the network equipment of the core layer such as GPON OLT and convergence-level.This time, the MIB quantity that managed device need to be realized and the management function of network management system have also significantly increased, the MIB traffic that NMS is unified between the managed device also will strengthen, and because the restriction of IP message length and the restriction of SNMP self efficient, the MIB limited amount that the SNMP communication message carries, need repeatedly communication just can finish complicated batch webmaster operation, thereby the communication efficiency that causes NMS to unify between the managed device is lower.

Summary of the invention

Technical problem to be solved by this invention is to solve unify the lower problem of communication efficiency between the managed device of NMS.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides the processing method of a kind of batch MIB, may further comprise the steps:

The batch mib information that network management system need to operate managed device simultaneously is encapsulated in the command file and sends to managed device, when the size of described command file surpasses the maximum payload that the IP message can carry, compress described command file and write compression at the head of described command file and indicate;

Whether managed device receives described command file, have the compression sign to judge whether this command file is decompressed according to the head of described command file;

Managed device is resolved described command file and is obtained in batches mib information, and according to corresponding processing of described mib information execution, again result is encapsulated as a response file, when the size of described response file surpasses the maximum payload that the IP message can carry, compress described response file and write compression at the head of described response file and indicate;

Whether network management system is obtained described response file, and have the compression sign to judge whether this response file is decompressed according to the head of described response file;

Network management system is resolved described response file and is obtained in batches mib information, and finishes corresponding network management according to described mib information.

In said method, network management system sends to managed device with described command file by SNMP SET order or FTPPUT order, obtains described response file by SNMP GET order or FTP GET order from managed device.

In said method, the maximum payload that described IP message can carry is long 1500 bytes of the maximum bag of an IP.

The present invention has adopted the mode based on compressed file to increase the mib information quantity of carrying in the communication, has improved the efficient of network management.

Embodiment

The invention provides the processing method of a kind of batch MIB, employing has increased the mib information quantity of carrying in the communication based on the mode of compressed file, reduced unify number of communications between the managed device of NMS, the SNMP communication that allows NMS unify between the managed device is prompt efficient more fast, improved the efficient of network management, promote real-time and the friendly of network management operation, thereby realized friendly user management experience.Below in conjunction with specification drawings and specific embodiments the present invention is made detailed explanation.

See also Fig. 1, the processing method of batch MIB provided by the invention comprises network management system handling process and two parts of managed device handling process, and concrete steps are as follows:

The network management system handling process may further comprise the steps:

Step 101, the batch mib information that network management system need to be managed managed device (comprising the contents such as OID, type, value) is encapsulated as a command file according to specific format;

Step 102 checks whether the size of command file has surpassed long 1500 bytes of maximum bag that the IP message can carry, if surpass, then execution in step 103, otherwise execution in step 104;

Step 103 adopts universal compressed method compress order file, and writes the compression sign at the head of command file, turns step 104;

Step 104 is issued to managed device by FTP PUT or SNMP SET with command file;

Step 105, whether the periodic test managed device has finished the processing of command file, if finish, enters step 106;

Step 106 is obtained response file by FTP GET or SNMP GET from managed device;

Step 107 checks whether the head of the response file that gets access to comprises the compression sign, if compression sign, execution in step 108, otherwise execution in step 109 are arranged;
