Description
Technical field
The invention belongs to the Snmp protocol realization technical fields in network communication technology, more particularly to a kind of isomery redundancy
The more examples of Snmp agreements realize system and its implementation.
Background technology
Core component of the router as network infrastructure, the security situation of its own are increasingly serious.And Snmp
Important component of the agreement as router administration plane realizes the configuration management, inquiry and alarm announcement function of router,
Its security situation also allows of no optimist.Snmp agreements mainly face the attack from loophole or back door.Conventional router passes through repairing
Snmp protocol bugs increase attack of the additional security mechanism reply based on known bugs or back door, to unknown loophole or after
Door is helpless, and mainly conventional method can not be fully solved fundamentally there is no the static characteristic for changing Snmp agreements
The fragile sex chromosome mosaicism of Snmp agreements and Mib information.
Invention content
To overcome deficiency of the prior art, the present invention provide a kind of more examples of isomery redundancy Snmp agreements realize system and
Its implementation, solving single Snmp Failure Of Protocols in router of the prior art causes router administration plane to be asked extremely
Topic, is effectively ensured network communication normal operation.
According to designing scheme provided by the present invention, a kind of more examples of isomery redundancy Snmp agreements realize system, comprising
Snmp agent units, Snmp agreements perform module, dynamic dispatching unit, wherein, Snmp agent units are responsible for receiving from net
The Snmp agreement requests of tube terminal, and request message duplication is distributed to Snmp agreements and performs module；Snmp agreements perform body
Module is handled according to Snmp agreement request types, handling result is sent to dynamic dispatching unit, Snmp agreements perform body
Module includes N number of isomery Snmp agreements run parallel and performs body unit；Dynamic dispatching unit safeguards that isomery Snmp agreements perform
Body unit is selected more preferable mechanisms to all Snmp agreements execution body unit operation result foundations and is arbitrated, from isomery Snmp
Agreement performs the normal Snmp agreements of one operating status of selection in body unit and performs woker marks in body unit juxtaposition, will be secondary
Cut out result and be transmitted to route control unit or data forwarding unit accordingly according to Snmp agreement requests type, wherein, N be more than
2 integer.
Above-mentioned, the Snmp agreement requests type of webmaster terminal includes Snmpset message, Snmpget message.
Above-mentioned, it is specifically as follows comprising content to select more preferable mechanisms：Multiple isomery Snmp agreements run parallel perform body
In unit, if the operation result that more than two Snmp agreements perform body unit is identical, by the most operation knot of same number
Fruit is as arbitration result, if the operation result that each Snmp agreements perform body unit is different, by the Snmp of highest priority
Agreement performs the operation result of body unit as arbitration result.
A kind of more example implementation methods of isomery redundancy Snmp agreements, it is real based on the above-mentioned more examples of isomery redundancy Snmp agreements
Existing system, specifically comprises the following steps：
Step 1, Snmp agent units receive webmaster terminal Snmp request commands, respectively with multiple isomeries run parallel
Snmp agreements perform body unit and establish internal Snmp session connections, replicate Snmp request commands and pass through internal Snmp session connections
It is distributed to each Snmp agreements and performs body unit, Snmp request commands include Snmpset orders, Snmpget orders；
Step 2, each Snmp agreements perform body unit and receive carries out operation after Snmp request commands respectively, and by operation
As a result it is advertised to dynamic dispatching unit；
Step 3, dynamic dispatching unit perform body unit operation result according to each Snmp agreement and carry out maintenance management simultaneously
It is arbitrated according to more preferable mechanisms are selected, is performed from isomery Snmp agreements and a normal Snmp of operating status is selected in body unit
Agreement performs woker marks in body unit juxtaposition, and arbitration result is transmitted to routing accordingly according to Snmp agreement requests type
Control unit or data forwarding unit.
Above-mentioned implementation method, step 2 specifically include following content：It is received when Snmp agreements perform body unit
During Snmpset orders, configuration data is obtained, and configuration data is notified to dynamic dispatching unit；When Snmp agreements perform body list
When member receives Snmpget orders, the variate-value to be inquired is obtained, and query result is notified to dynamic dispatching unit.
Above-mentioned implementation method, dynamic dispatching unit performs body unit operation knot according to each Snmp agreement in step 3
Fruit carries out maintenance management and is arbitrated according to more preferable mechanisms are selected, specifically comprising following content：Dynamic dispatching unit foundation
Snmp agreements perform the configuration data of body unit notification or query result carries out maintenance management, multiple isomery Snmp run parallel
Agreement is performed in body unit, if the operation result that more than two Snmp agreements perform body unit is identical, by same number most
More operation results are as arbitration result, if the operation result that each Snmp agreements perform body unit is different, by priority
Highest Snmp agreements perform the operation result of body unit as arbitration result.
Above-mentioned implementation method, dynamic dispatching unit performs body unit operation knot according to each Snmp agreement in step 3
Fruit carries out maintenance management and is arbitrated according to more preferable mechanisms are selected, also comprising following content：In arbitrated procedure is carried out, if hair
Some existing Snmp agreement performs body unit operation irregularity, and the Snmp agreements of the operation irregularity are performed body unit by dynamic dispatching unit
Working condition is cut out, and is reset so that Snmp agreements perform body unit and are restored to normal original state；Dynamic dispatching unit
Monitoring Snmp agreements perform body unit state in real time, when monitoring that Snmp agreements perform body unit failure or the company of mistake, pass through band
The Snmp agreements are performed body unit place machine and restarted by outer tunnel so that Snmp agreements perform body unit and are restored to normal initial shape
State.
Beneficial effects of the present invention：
1st, of the invention since multiple parallel isomery Snmp agreements perform body units, this isomerism determines different Snmp
