Abstract

A method for managing distributed-mode system in network includes receiving message carried with MIB instance name and sent from management station by control center and comparing received MIB instance name carried by message with retransmission rule stored in said center separately to judge whether received MIB instance name is matched to MIB number recorded in retransmission rule or not, retransmitting said message to distributed-mode system controlled device recorded in retransmission rule.

Description

A kind of in network the method for managing distributing type system

Technical field

The present invention relates to network management technology, particularly relate to a kind of Simple Network Management Protocol (SNMP, Simple Network Managing Protocol) method of managing distributing type system in network of utilizing.

Background technology

In catenet, often comprise one or more distributed system.Each distributed system is made up of a control centre and several controlled devices.For example, by the storage system that a storage control and several disk chassis are formed, wherein storage control is exactly the control centre of storage system, and each disk chassis is exactly a controlled device of storage system.In catenet, generally utilize SNMP that all network elements that comprise each distributed system in the network are managed by network management workstation.

Network management workstation to certain Distributed System Management in, need to be provided with simultaneously/to obtain the information of a plurality of controlled devices in this distributed system sometimes.This just needs described control centre to have SNMP message forwarding capability, and the SNMP message of network management workstation being sent according to certain forwarding rule is forwarded on the control corresponding object.

The technical scheme of existing techniques in realizing above-mentioned functions is, according to snmp protocol, several controlled devices are corresponded to group's name/safety name, send in the SNMP message of control centre at network management workstation, as long as specified group's name/safety name, control centre just can be transmitted to corresponding apparatus with the SNMP message according to above-mentioned corresponding relation.Because network management workstation sends to the SNMP message of control centre and has all kinds, the controlled device combination that every type SNMP message need be visited has nothing in common with each other, and therefore a plurality of groups name/safety name need be set represent these combinations.Certainly, also several controlled devices can be corresponded to SNMP operation, according to the operation and the described corresponding relation of the SNMP message of being received the SNMP message is transmitted to corresponding apparatus by control centre then.

For example, in a distributed system, 4 controlled devices are arranged: first controlled device, second controlled device, the 3rd controlled device and the 4th controlled device.When group's name/user name is set, first controlled device, second controlled device are corresponded to first group name/safety name; Second controlled device, the 3rd controlled device are corresponded to second group name/safety name; The 4th controlled device is corresponded to the 3rd group name/safety name, or the like.

The shortcoming of prior art is, described SNMP message forwarding can only be operated according to group's name/safety name or SNMP and be carried out.In actual applications, for convenient management, a large amount of group's names/safety name can not be set, so the number of group's name/safety name is limited; And the number of SNMP operation has only the several of minority especially.But during the controlled device in network management workstation visit distributed system, access object has a large amount of combinations, and only adopting group's name/safety name and SNMP to operate can't these combination of perfect representation.For example in above-mentioned example, the combination of first controlled device and the 4th controlled device is not just by group's name/safety name expression.Like this, when network management workstation need be provided with/obtain the information of a plurality of controlled devices in this distributed system simultaneously, and the combination of described a plurality of controlled devices is not by group's name/safety name and SNMP operation expression the time, just can only send the SNMP message respectively to these controlled devices respectively, thereby reduce the efficient of network management.

Description of drawings

Fig. 1 be provided by the invention in network the method flow diagram of managing distributing type system.

Embodiment

Core concept of the present invention is: network management workstation sends the SNMP message to the control centre of distributed system, control centre adopts the MIB Instance Name as transmitting foundation, described SNMP message is transmitted to the controlled device of self controlling, returns to network management workstation after the response message reorganization of then controlled device being returned.

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and the specific embodiments.

In a SNMP message, carry a MIB Instance Name to I haven't seen you for ages; According to the SNMP operation that message will carry out, also may carry the MIB value corresponding with this MIB Instance Name, it is right to constitute a MIB Instance Name/MIB value.The MIB Instance Name is used to specify the mib object example that needs visit, it is by the object identifier (OID of mib object, Object Identifier) adds that the example index constitutes, a mib object may have a plurality of examples, in the Instance Name of these examples, the identical and example index difference of object identifier; The MIB value then is used to represent the value of this MIB example.Be an example that the MIB Instance Name/the MIB value is right below:

1.3.6.1.2.1.1.1.0＝‘abc’

The point minute numeral on the equal sign left side is exactly the MIB Instance Name, and wherein 1.3.6.1.2.1.1.1 is the OID of described mib object, and last position 0 is exactly described example index, equal sign the right ' abc ' is exactly described MIB value.Here in order to narrate conveniently, adopt each numeral in the decimal representation MIB Instance Name, represent with binary digit in the reality, for example, suppose that then 1.3.6.1.2.1.1.1.0 should be expressed as 00000001.00000011.00000110.00000001.00000010.00000001.00 000001.00000001.00000000 in practice with each numeral in the byte representation MIB Instance Name.

SNMP message based on the MIB Instance Name provided by the present invention is transmitted scheme, is exactly in fact that control centre decides how to transmit the SNMP message according to a few numerals in the MIB Instance Name in the SNMP message of being received.

Suppose in a distributed system, 2 controlled devices are arranged: first controlled device, second controlled device.Wherein, the Internet protocol of first controlled device (IP, Internet Protocol) address is 1.2.3.4, and the IP address of second controlled device is 1.2.3.5.

In first embodiment, in entrained MIB Instance Name, preceding several numerals are forwarded to designated equipment for the SNMP message of specifying numerical value.For example, suppose the SNMP message that preceding 7 numerals of entrained MIB Instance Name are 1.3.6.1.2.1.1 is forwarded to first controlled device and second controlled device, can in control centre, add following two and transmit rule:

1.3.6.1.2.1.1 1.2.3.4

1.3.6.1.2.1.1 1.2.3.5

Wherein, the first half of every rule is an OID or Instance Name, in order to narrate conveniently, is referred to as MIB number; Latter half is the address of a controlled device.Suppose that network management workstation sends to entrained MIB example 1.3.6.1.2.1.1.2, totally 8 bit digital by name of SNMP message of control centre.After the SNMP message that network management workstation sends is received by control centre, find that preceding 7 numerals of the MIB Instance Name that carries in the described SNMP message are 1.3.6.1.2.1.1, just described SNMP message is transmitted to first controlled device and second controlled device respectively.Suppose that again network management workstation sends to entrained MIB example 1.3.6.1.2.1.1.2.8, totally 9 bit digital by name of SNMP message of control centre.After the SNMP message that network management workstation sends is received by control centre, find that preceding 7 numerals of the MIB Instance Name that carries in the described SNMP message are 1.3.6.1.2.1.1, also described SNMP message is transmitted to first controlled device and second controlled device respectively.

In the above-described embodiments, can only utilize preceding several numerals of the MIB Instance Name that carries in the SNMP message as transmitting foundation.The numeral that can utilize the optional position in the MIB Instance Name if desired then needs further to add the MIB mask as transmitting foundation in transmitting rule.In addition, as previously mentioned, in the message of reality, the numeral in the MIB Instance Name all is to represent with the form of binary number, after having added described MIB mask, can also further utilize some binary digit in the described MIB Instance Name as transmitting foundation.

For example, if the MIB Instance Name first digit that carries in SNMP message is 1, third digit is 6, then this SNMP message is forwarded to first controlled device and second controlled device, at this moment can add following two and transmit rule in control centre:

1.0.6.0.0.0.0 0xff.0.0xff.0.0.0.0 1.2.3.4

1.0.6.0.0.0.0 0xff.0.0xff.0.0.0.0 1.2.3.5

Wherein, 0xff.0.0xff.0.0.0.0 is described MIB mask, in order to narrate conveniently, adopts hexadecimal number to represent that each numeral in the MIB mask is represented with one 8 bit in practice here.In the narration below, the numeral that every front has 0x all is to use hexadecimal representation.Transmit in the rule at every, the numeral in the MIB mask, with numeral in MIB number be to concern one to one.When the numeral in the numeral in the MIB mask and MIB number is all used binary representation, the binary digit in every MIB mask of transmitting in the rule, with binary digit in MIB number also be to concern one to one.

Control centre is when whether SNMP message that judgement is received is transmitted rule and be complementary with certain bar, only judge the MIB Instance Name that carries in the SNMP message, with MIB number that transmits in the rule, the MIB mask be 1 those the position on whether identical, if identical would think message with transmit rule match, otherwise think and do not match.In concrete operations, MIB Instance Name entrained in the message can be carried out step-by-step and operation with the MIB mask, if the result who obtains with transmit rule in MIB number identical think message with transmit rule match.For example, the example that carries in SNMP message 1.3.6.1.2.1.1 by name, with MIB mask 0xff.0.0xff.0.0.0.0 step-by-step with the operation after, the result who obtains is 1.0.6.0.0.0.0, with above-mentioned two rule couplings, then control centre is transmitted to first controlled device and second controlled device with this SNMP message.

If two above-mentioned forwarding rules modifications are become form as follows:

0.0.0.0.0.0x30.0 0.0.0.0.0.0xf0 1.2.3.4

0.0.0.0.0.0x30.0 0.0.0.0.0.0xf0 1.2.3.5

Then as long as high 4 of the 6th numeral of the entrained MIB Instance Name of SNMP message be binary zero 011, control centre just thinks and this message and above two regular couplings message is transmitted to by first controlled device and second controlled device.

Certainly, can stipulate that also control centre is when whether SNMP message that judgement is received is transmitted rule and be complementary with certain bar, only judge the MIB Instance Name that carries in the SNMP message, with MIB number that transmits in the rule, the MIB mask be 0 those the position on whether identical, if identical would think message with transmit rule match, otherwise think and do not match.

When being set, the forwarding rule it is noted that for same control centre the forwarding rule of repetition should not arranged.For example, such situation should not appear: transmit rule according to article one, if high 4 of the 6th numeral of the entrained MIB Instance Name of SNMP message are 1 entirely, then this SNMP message is transmitted to first controlled device; Transmit rule according to second,, then this SNMP message is transmitted to first controlled device if all positions of the 6th numeral of the entrained MIB Instance Name of SNMP message are 1 entirely.Obviously, the situation that second is transmitted rule has been included in article one forwarding rule, therefore second should be set again transmit rule.Certainly, if transmit rule,, then this SNMP message is transmitted to first controlled device, the forwarding rule that such situation does not repeat at last if low 6 of the 6th numeral of the entrained MIB Instance Name of SNMP message is 1 entirely according to second.

According to the method described above, network management workstation can be provided with forwarding rule as implied above as required flexibly, and set forwarding rule downloading is arrived control centre.Control centre preserves the forwarding rule that network management workstation issued.Control centre is receiving behind the SNMP message that network management workstation is sent, the SNMP message is forwarded to the controlled device of appointment according to the forwarding rule of being preserved, and, reorganize the SNMP message then the result is returned to network management workstation from designated equipment acquisition corresponding results.

For described forwarding rule is set, network management workstation need be provided with the value of following six mib objects according to snmp protocol, then these six mib objects is offered control centre.These six mib objects lump together one of expression and transmit rule.

Need to prove that last table has just provided the example that is used to be provided with the mib object tabulation of transmitting rule.Wherein srnmpRelayProMappingIndex is used to represent to transmit the sequence number of rule, and the forwarding number of regulation in the same control centre is unduplicated; SnmpRelayProMappingName is used for representing transmitting MIB number of rule; SnmpRelayProMappingMask is used for representing to transmit the MIB mask of rule, and for the situation that does not adopt the MIB mask, this mib object can not provide; SnmpRelayProMappingOper is used for expression and transmits regular pairing SNMP operation, i.e. this forwarding rule is only effective to the SNMP message that carries out the specified operation of snmpRelayProMappingOper, and this mib object can not provide yet; SnmpRelayProMappingDest is used for expression and transmits regular pairing controlled device address, represents with 32 IP addresses in existing snmp protocol, as required also can for example 64 IP addresses or MAC Address are represented with other forms; SnmpRelayProMappingRowStatus is used to represent to transmit the state of rule, thereby creates or delete this forwarding rule.

Please refer to Fig. 1, Fig. 1 be provided by the invention in network the method flow diagram of managing distributing type system.This flowcharting the handling process of control centre after receiving the SNMP message that network management workstation sends of distributed system.

Step U01: the SNMP message that the receiving management work station is sent.

Step U02: all that self is preserved are transmitted rule and are transmitted rule as being untreated.

Described forwarding rule is to be provided with by providing to control centre in above-mentioned 6 mib objects by management work station.

Step U03: never choose one in the processing forward rule wantonly as current forwarding rule.

In the narration of step U07, suppose that current forwarding rule is at following steps U04:

1.0.6.0.0.0.0 0xff.0.0xfff.0.0.0.0 1.2.3.4

Step U04: with the MIB mask of putting down in writing in the current forwarding rule, with step-by-step of example masterpiece and operation entrained in the SNMP message that is received.

Step U05: the result who obtains among the determining step U04, whether with current forwarding rule in MIB number coupling putting down in writing, if mate then execution in step U06, otherwise execution in step U07.

If in the SNMP message the digital number of entrained Instance Name with transmit rule in the digital number of the MIB mask put down in writing identical, said so here coupling refer among the step U04 to the result and current forwarding rule in put down in writing MIB number identical.

If the digital number m of entrained Instance Name is greater than the digital number n of transmitting the MIB mask of putting down in writing in the rule in the SNMP message, then only get in the Instance Name entrained in the SNMP message before n numeral and MIB mask carry out step-by-step and operation.For example, if entrained example is called 1.3.6.1.2.1.1.3.5 totally 9 numerals in the SNMP message, and the MIB mask of being put down in writing in the forwarding rule is 0xff.0.0xff.0.0.0.0 totally 7 numerals, then only get in the entrained Instance Name of SNMP message 1.3.6.1.2.1.1 totally 7 numerals with transmit the MIB mask of being put down in writing in the rule and carry out step-by-step and operation, the result who obtains is 1.0.6.0.0.0.0.In this case, said here coupling refers to also be among the step U04 to the result and current forwarding rule in put down in writing MIB number identical.

If the digital number m of entrained Instance Name is less than the digital number n of transmitting the MIB mask of putting down in writing in the rule in the SNMP message, then can carry out the zero padding operation to the Instance Name that carries in the SNMP message, the Instance Name trailing zero of promptly carrying in the SNMP message is n up to the digital number of Instance Name.In this case, said here coupling refers to also be among the step U04 to the result and current forwarding rule in put down in writing MIB number identical.

If the digital number m of entrained Instance Name is less than the digital number n of transmitting the MIB mask of putting down in writing in the rule in the SNMP message, also can only gets Instance Name entrained in preceding m numeral transmitting the MIB mask put down in writing in the rule and the SNMP message and carry out step-by-step and operation.In this case, said here coupling refers to resulting result among the step U04, and is identical with MIB number that puts down in writing in the current forwarding rule preceding m numeral.

Certainly, be not equal to the situation of the digital number of transmitting the MIB mask of putting down in writing in the rule for the digital number of Instance Name entrained in the SNMP message, can think directly that also the Instance Name that carries in the SNMP message and MIB number of current forwarding regular record do not match.

Step U06: described SNMP message is sent to the controlled device of putting down in writing in the current forwarding rule.

Step U07: with current forwarding rule as processing forward rule

Step U08: judge that whether all of self preserving are transmitted rules all is processing forward rule, if execution in step U09 then, otherwise return execution in step U03.

Step U09: finish current flow process.

Above flow process at be network management workstation when control centre is provided for the mib object of transmitting rule is set, the situation of other five objects except that the snmpRelayProMappingOper object is provided.That is to say that control centre is not judged the operation that the SNMP message of receiving from network management center will carry out.If network management workstation further provides snmpRelayProMappingOper object to control centre, then control centre also needs to judge the operation that the SNMP message received from network management center will carry out, whether identical with the SNMP operation put down in writing in the current forwarding rule, if inequality then current forwarding rule is labeled as processing forward rule, handle next bar then and transmit rule.

And if network management workstation does not provide snmpRelayProMappingMask when control centre is provided for the mib object of transmitting rule is set, promptly do not adopt the MIB mask, then step U04 can omit.And in step U05, control centre directly relatively in the SNMP message entrained Instance Name with transmit MIB number that puts down in writing in the rule, if both couplings then execution in step U06, otherwise execution in step U07.Be not equal to the situation of transmitting MIB number the digital number of putting down in writing in the rule for the digital number of Instance Name entrained in the SNMP message, the processing method when the digital number of entrained Instance Name is not equal to the digital number of transmitting the MIB mask put down in writing in the rule in the SNMP message described in can refer step U05 is handled.

In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
