Description

A kind of IRF division processing method and device
Technical field
The present invention relates to communication technical field, particularly a kind of IRF division processing method and device.
Background technology
IRF (Intelligent Resilient Framework, intelligent elastic framework) technology is a kind of software virtualization technology, its principle is that many physical equipments are coupled together by IRF port, carries out after necessary configuration, virtually turn to a logical device, be called IRF.Use IRF technology can gather hardware resource and the software disposal ability of multiple devices, powerful extended capability is provided, realize collaborative work, the unified management of multiple devices and uninterruptedly safeguard.
Every equipment in IRF is all called member device, divides according to function, and member device is divided into two kinds: primary (Master) equipment, be in charge of whole IRF; Subordinate (Slave) equipment, as the alternate device operation of host apparatus.In the time of host apparatus fault, system can be automatically electing a new host apparatus from equipment.IRF uses member's number-mark member device, to it is managed, all members number must be unique.The unique corresponding IRF territory of each IRF, is used Field Number (DomainID) to distinguish between IRF.IRF schematic diagram as shown in Figure 1, physical equipment A, B, C connect successively by IRF link, form an IRF.Wherein, device A is Master equipment, and other equipment are slave.Device A, B, C all dispose member's numbering that is different from other member devices.IRF self also disposes a Field Number that is different from other IRF.
IRF link failure can cause IRF to split into multiple IRF, and the multiple IRF that form after division have identical routing configuration, therefore can cause network failure, for example IP address conflict.Taking Fig. 1 as example, when after the IRF link failure between device A and equipment B, device A forms an IRF1; Equipment B and equipment C form another IRF2; IRF1 and IRF2 have identical IP address, therefore, after IRF1 and IRF2 are communicated with by other links, there will be IP address conflict.
In order to address the above problem, prior art provides MAD (Multi-Active Detection, multi-Active detects) mechanism.MAD mechanism has division detection, conflict processing, three kinds of functions of fault recovery, by carry out respective handling in the time IRF division being detected, can avoid dividing because of IRF the network failure causing.
There is at present multiple MAD division testing mechanism, for example, detect the division testing mechanism of (BFD) technology, the division testing mechanism based on Link Aggregation Control Protocol (LACP) expansion technique based on two-way converting.
LACP MAD division testing mechanism is realized by expansion LACP protocol massages content, be member device carrys out mutual IRF DomainID and ActiveID (for member's numbering of main equipment) by sending out mutually LACP protocol massages, determine whether to occur IRF division according to DomainID and ActiveID comparative result.Taking Fig. 2 as example, the principle of LACP MAD is elaborated below.
Referring to Fig. 2, Fig. 2 is the IRF networking schematic diagram of prior art based on LACP MAD, and Fig. 2 is based on Fig. 1, and device A, equipment B, equipment C are connected to form IRF by IRF link successively, and are all connected with intermediate equipment by polymerization Member Link.
Device A sends the LACP protocol massages that carries DomainID and ActiveID to intermediate equipment by polymerization Member Link, obtain wherein DomainID and ActiveID and send to equipment B and equipment C by LACP protocol massages by intermediate equipment, make DomainID and the ActiveID of equipment B and equipment C equipment A place IRF, and compare with DomainID and the ActiveID of self place IRF, DomainID difference, do not belong to same IRF, do not need to carry out MAD processing; DomainID and ActiveID are all identical, and IRF division does not occur; DomainID is identical and ActiveID is different, and IRF division occurs.In like manner, equipment B and equipment C also all can send the LACP protocol massages that carries DomainID and ActiveID to intermediate equipment by polymerization Member Link, and are forwarded to other each member device by intermediate equipment.Finally, all member devices all determine whether to occur IRF division according to DomainID and ActiveID comparative result.
Suppose to form after the IRF link failure between device A and equipment B IRF1 (only comprise a member device: device A) and IRF2 (comprise two member devices: equipment B and equipment C); The DomainID of IRF1 and IRF2 is identical, and ActiveID difference now, in the time that device A, equipment B and equipment C pass through the mutual DomainID of intermediate equipment and ActiveID, will detect IRF division.After IRF division, the IRF of ActiveID minimum works on, and other IRF enters Recovery state, temporarily not at forwarding service message.
In reality realizes, because adopting different expansion LACP protocol massages to realize LACPMAD division, different vendor detects, and the practical function of intermediate equipment is not identical yet, causes the selection of intermediate equipment limited.In addition, in the time that IRF member device receives that the ActiveID carrying is different from the LACP protocol massages of ActiveID of self place IRF, will determine that IRF occurs to be divided and carry out corresponding division and process, if IRF member device is received the message of this malicious attack on network, will bring potential safety hazard to IRF.In addition, after IRF division, only determine according to ActiveID size the IRF that continues normal operation, cannot select optimum IRF and continue bearer traffic, for example, the equipment that the IRF that continues normally to move comprises is less, transfer capability a little less than, and for example, if it is to cause IRF division because of the interface board of IRF member device or the forwarding fault that web plate causes that IRF divides, after IRF division, this IRF member device place IRF will there will be forwarding fault, should not be selected as the IRF of normal operation, but, existing method cannot be got rid of this IRF member device place IRF and be selected as the possibility of the IRF of normal operation.

When the member device information of the device A receiving as equipment C, by member device information quality relatively, determine that the member device information of equipment C is better than the member device information of device A, therefore keep equipment C to connect the selected state of the port of intermediate equipment; In the time that equipment C receives the member device information of equipment B, by comparing member device information quality, determine that the member device information of equipment C is identical with the member device information of equipment B, therefore keep equipment C to connect the selected state of the port of intermediate equipment.
Can find out, according to method shown in Fig. 3, after IRF division, in the IRF1 being made up of device A, all service ports except the port of device A connection intermediate equipment are all closed, and IRF1 does not bear data traffic and forwards.In the IRF2 being made up of equipment B and equipment C, all service ports are not all closed, and therefore IRF2 bears data traffic forwarding.
Referring to Fig. 4, Fig. 4 is the embodiment of the present invention two IRF division process flow figure, and in IRF, each member device is all connected with an intermediate equipment, and the port that initially in IRF, each member device connects described intermediate equipment is selected state.The method mainly comprises the following steps:
In step 401, IRF, the member device information of self is sent to intermediate equipment by arbitrary member device.
Step 402, intermediate equipment receive after this member device information, the relatively optimum member device information of this member device information and intermediate equipment current record, if this member device information is better than the optimum member device information of intermediate equipment current record, the optimum member device information of upgrading intermediate equipment current record is this member device information, and by this member device information announcement to other each member device in IRF, go to step 403, otherwise, this member device information abandoned.
Step 403, other each member device receive after this member device information, whether the member device information that judgement receives is better than the member device information of self, if, the port that self connects described intermediate equipment is set to the non-port of choosing, close choose all service ports port except this is non-, otherwise, keep the selected state of the port that self connects described intermediate equipment.
Shown in Fig. 4 in the embodiment of the present invention, described member device information comprises priority, member device number, ActiveID of the OUI of company mark, Field Number, the current place IRF of member device etc.Can be successively according to the current place of member device IRF priority, member device number, the relatively quality of two member device information of ActiveID order, the method of concrete relatively two member device information qualities of method and middle comparison embodiment illustrated in fig. 3 of two member device information qualities is identical, repeats no more.
Taking Fig. 2 as example, the embodiment of the present invention shown in Fig. 4 is illustrated below.
Suppose in Fig. 2, the priority of the IRF being made up of device A, equipment B and equipment C is 1, member's numbering of device A, equipment B, equipment C is respectively: 10,20,30, the ActiveID of this IRF is 10 (member numbers minimum member device and is elected as Master equipment, and the ActiveID of IRF is member's numbering of Master equipment); When initial, the port of device A, equipment B, equipment C connection intermediate equipment is chooses port.
The disposition that IRF does not divide:
When IRF does not divide, (IRF priority is 1 to the member device information that device A, equipment B, equipment C send to intermediate equipment, IRF member device number is 3, the ActiveID of IRF is 10) all identical, therefore intermediate equipment only arrives other member device by the member device information announcement of receiving at first, after this member device information of receiving is identical with the member device information of receiving at first, therefore, does not carry out member device notice.
Suppose that intermediate equipment receives the member device information that device A sends at first, not yet record optimal device information because intermediate equipment is current, therefore the member device information that is device A by optimal device information updating, simultaneously by the member device information announcement of device A to equipment B and equipment C.
When equipment B receives the member device information of device A, because the member device information of the member device information and equipment B self that receives is identical, and can keep self connecting the selected state of intermediate equipment, can not close all service ports of self.
When equipment C receives the member device information of device A, because the member device information of the member device information and equipment C self that receives is identical, and can keep self connecting the selected state of intermediate equipment, can not close all service ports of self.
And because device A is not received the member device information of equipment B and equipment C all the time, therefore its port that connects intermediate equipment is always selected state, service port also can not be closed.Finally, all service ports in IRF are not all closed, and IRF normally moves.
Can find out, according to method shown in Fig. 4, when IRF does not divide, IRF normally works, and can not produce any impact to IRF traffic forwarding.
The disposition of IRF division:
Cause IRF to be split into after IRF1 (being made up of device A) and IRF2 (being made up of equipment B and equipment C) when the IRF link between device A and equipment B disconnects, the priority of IRF1 and IRF2 and the priority of original IRF are consistent, and are still 1; The member device number of IRF1 is that 1, ActiveID is 10; The member device number of IRF2 is that 2, ActiveID is 20.
Therefore,, in the member device information of device A, IRF priority, member device number and ActiveID are respectively 1,1,10; In the member device information of equipment B, IRF priority, member device number and ActiveID are respectively 1,2,20; The member device information of equipment C is identical with the member device information of equipment B.
Device A, equipment B and equipment C all can send to intermediate equipment the member device information of self, and are determined whether the member device information announcement receiving to other member device according to the odds of the optimum member device information of the member device information receiving and current record by intermediate equipment.Suppose that intermediate equipment receives the member device information of device A, equipment B, equipment C transmission successively,,
In the time that intermediate equipment receives the member device information of device A, the member device information that is device A by the optimum member device information updating of current record, and by the member device information announcement of device A to equipment B and equipment C.When equipment B receives the member device information of device A, by comparing member device information quality, determine that the member device information of self is better than the member device information of device A, therefore keep self connecting the selected state of the port of intermediate equipment.When equipment C receives the member device information of device A, by comparing member device information quality, determine that the member device information of self is better than the member device information of device A, therefore keep self connecting the selected state of the port of intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment B, the quality of the optimum member device information (being now the member device information of device A) of the member device information of compare facilities B and intermediate equipment current record, determine that the member device information of equipment B is better than the optimum member device information of intermediate equipment current record, therefore, the member device information that is equipment B by the optimum member device information updating of intermediate equipment current record, and by the member device information announcement of equipment B to device A and equipment C.When device A receives the member device information of equipment B, by comparing member device information quality, determine that the member device information of self is inferior to the member device information of equipment B, the port that therefore self connects intermediate equipment is set to not selected state, and closes all service ports of self.When equipment C receives the member device information of equipment B, by comparing member device information quality, determine that the member device information of self is identical with the member device information of equipment B, therefore keep self connecting the selected state of the port of intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment C, the quality of the optimum member device information (being now the member device information of equipment B) of the member device information of compare facilities C and intermediate equipment current record, determine that the member device information of equipment C is identical with the optimum member device information of intermediate equipment current record, therefore, do not carry out member device notice.
Can find out, in method shown in Fig. 4, after IRF division, intermediate equipment is by comparing the optimum member device information of the member device information receiving and current record, only in the time that the member device information receiving is better than the optimum member device information of current record, just proceed member device information exchange mistake, with respect to method shown in Fig. 3, can reduce bandwidth resources waste.And according to method shown in Fig. 4, after IRF division, in the IRF1 being made up of device A, all service ports are all closed, IRF1 does not bear data traffic and forwards.In the IRF2 being made up of equipment B and equipment C, all service ports are not all closed, and therefore IRF2 bears data traffic forwarding.
Referring to Fig. 5, Fig. 5 is the embodiment of the present invention three IRF division process flow figure, and in IRF, each member device is all connected with an intermediate equipment, and the port that requires each member device in initial IRF to connect described intermediate equipment is selected state.The method mainly comprises the following steps:

Therefore,, in the member device information of device A, IRF priority, member device number and ActiveID are respectively 1,1,10; In the member device information of equipment B, IRF priority, member device number and ActiveID are respectively 1,2,20; The member device information of equipment C is identical with the member device information of equipment B.
Device A, equipment B and equipment C all can send to intermediate equipment the member device information of self, and determined whether the member device information announcement receiving to other member device according to the odds of the optimum member device information of the member device information receiving and current record by intermediate equipment, suppose that intermediate equipment receives the member device information of device A, equipment B, equipment C transmission successively,
In the time that intermediate equipment receives the member device information of device A, the member device information that is device A by the optimum member device information updating of current record, and by the member device information announcement of device A to equipment B and equipment C.When equipment B receives the member device information of device A, by comparing member device information quality, determine that the member device information of self is better than the member device information of device A, therefore keep self connecting the selected state of the port of intermediate equipment.When equipment C receives the member device information of device A, because equipment B is Master equipment, equipment C is Slave equipment, therefore the member device information of device A is sent to equipment B; Equipment B is by the quality of the member device information of the member device information that relatively receives and equipment C, determines the member device information that the member device information of equipment C is better than receiving, and therefore keeps equipment C to connect the selected state of the port of intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment B, the quality of the optimum member device information (being now the member device information of device A) of the member device information of compare facilities B and intermediate equipment current record, determine that the member device information of equipment B is better than the optimum member device information of intermediate equipment current record, therefore, the member device information that is equipment B by the optimum member device information updating of intermediate equipment current record, and by the member device information announcement of equipment B to device A and equipment C.When device A receives the member device information of equipment B, because certainly as Master equipment, therefore by comparing member device information quality, determine that the member device information of self is inferior to the member device information of equipment B, therefore the port that self connects intermediate equipment is set to not selected state, again because IRF1 only comprises that the port of device A and device A connection intermediate equipment is the non-port of choosing, the therefore all service ports outside the port of closing device A connection intermediate equipment.When equipment C receives the member device information of equipment B, because equipment B is Master equipment, equipment C is Slave equipment, therefore the member device information of equipment B is sent to equipment B; Equipment B, by the quality of the member device information of the member device information that relatively receives and equipment C, determines that the member device information of equipment C is identical with the member device information receiving, and therefore keeps equipment C to connect the selected state of the port of intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment C, the quality of the optimum member device information (being now the member device information of equipment B) of the member device information of compare facilities C and intermediate equipment current record, determine that the member device information of equipment C is identical with the optimum member device information of intermediate equipment current record, therefore, do not carry out member device notice.
Can find out, in method shown in Fig. 5, after IRF division, intermediate equipment is by comparing the optimum member device information of the member device information receiving and current record, only in the time that the member device information receiving is better than the optimum member device information of current record, just proceed member device information announcement, with respect to method shown in Fig. 3, can reduce bandwidth resources waste.And according to method shown in Fig. 4, after IRF division, in the IRF1 being made up of device A, all service ports are all closed, IRF1 does not bear data traffic and forwards.In the IRF2 being made up of equipment B and equipment C, all service ports are not all closed, and therefore IRF2 bears data traffic forwarding.
Referring to Fig. 6, Fig. 6 is the embodiment of the present invention four IRF division process flow figure, and in IRF, each member device is all connected with an intermediate equipment, and the port that initially in IRF, each member device connects described intermediate equipment is selected state; IRF and intermediate equipment have all been enabled LACP agreement, and the LACP priority of IRF is greater than the LACP priority of intermediate equipment.The method mainly comprises the following steps:
In step 601, IRF, arbitrary member device is carried at the member device information of self in LACP protocol massages and sends to intermediate equipment.
In actual applications, enable in the interconnect equipment of LACP agreement, the side that LACP priority is higher holds as reference, preferentially chooses port, and the port of choosing that one end that LACP priority is lower is selected according to the higher one end of LACP priority is determined the port of choosing of local terminal.
In the present embodiment, described member device information comprises system information and port information, wherein, system information comprises the information such as the priority, member device number, ActiveID of the OUI of company mark, Field Number, the LACP priority of member device, the current place IRF of member device; Port information comprises that member device connects the port id of described intermediate equipment.Here, in IRF, the LACP priority of the LACP priority and IRF of each member device self is identical.
This member device also receives the LACP protocol massages of the intermediate equipment information of carrying that intermediate equipment sends, and by relatively the LACP priority of this member device self and the LACP priority of the intermediate equipment that intermediate equipment packets of information contains, determines that IRF is reference edge.
Step 602, intermediate equipment receive this member device information being carried in LACP protocol massages, the relatively optimum member device information of this member device information and intermediate equipment current record, if this member device information is better than the optimum member device information of intermediate equipment current record, the optimum member device information of upgrading intermediate equipment current record is this member device information, and by this member device information announcement to other each member device in IRF, go to step 603, otherwise, abandon this member device information.
Intermediate equipment receives after this member device information being carried in LACP protocol massages, also by relatively the LACP priority of this member device and the LACP priority of intermediate equipment determine that IRF is reference edge.
Step 603, other each member device receives after this member device information, if certainly as Master equipment, whether the member device information that judgement receives is better than the member device information of self, if, when the system information containing when the member device packets of information receiving is better than the system information of this member device, the port that this member device connects described intermediate equipment is set to the non-port of choosing, and further judge whether the port that all member devices in self place IRF connect described intermediate equipment is the non-port of choosing, each member device in self place IRF to be connected to all service ports outside the port of described intermediate equipment to close and (be also, the all service ports that self connect described intermediate equipment are closed, the all service ports that simultaneously also other each member device of self place IRF connected outside the port of described intermediate equipment are closed), the system information containing when the member device packets of information receiving is inferior to the system information of this member device or when identical with the system information of this member device, abandons the member device information receiving, if from as Slave equipment, the member device information receiving is sent to Master equipment.
Shown in Fig. 5, the embodiment of the present invention further comprises: arbitrary member device is during as Master equipment, if receive the member device information that Slave equipment is sent, the quality of the member device information of this member device information receiving and Slave equipment relatively, if the member device information that this receives is better than the member device information of Slave equipment, in the time that the system information that the member device packets of information that this receives contains is better than the system information in the member device information of Slave equipment, described in Slave equipment connection, the port of intermediate equipment is set to the non-port of choosing, and further judge whether the port that each member device in the current place IRF of this member device connects described intermediate equipment is the not non-port of choosing, that all service ports that each member device in current this member device place IRF connected outside the port of described intermediate equipment are closed, when the system information that the member device packets of information that this receives contains is inferior to system information in the member device information of Slave equipment or when identical with system information in the member device information of Slave equipment, abandons the member device information that this receives.
Shown in Fig. 6, in the embodiment of the present invention, relatively the method for two member device information qualities is: system information is member device preferably, and its member device information is more excellent; When the system information of two member devices is identical, the member device that port id is less, its member device information is more excellent.
Before and after IRF division, the OUI of the company mark of member device wherein, the information such as Field Number can not change (if the member device information receiving is different from the member device information of self, illustrate that IRF division the first two member device does not belong to an IRF, can directly abandon the member device information receiving, this is same as the prior art), therefore in the good and bad process of comparison member device information, can not compare, therefore, relatively the method for the system information quality of two member devices is: the member device that LACP priority is higher, its system information is more excellent, when the LACP priority of two member devices is identical, the higher member device of priority of current place IRF, its system information is more excellent, the LACP priority of two member devices and the priority homogeneous phase of current place IRF while, the more member device of member device number of current place IRF, its system information is more excellent, the LACP priority of two member devices, the priority of current place IRF and member device are counted homogeneous phase simultaneously, the less or larger member device of ActiveID of current place IRF, and its system information is more excellent.
Taking Fig. 2 as example, the embodiment of the present invention shown in Fig. 6 is illustrated below.
Suppose in Fig. 2, the LACP priority that the priority of the IRF being made up of device A, equipment B and equipment C is 1, IRF is 1; Member's numbering of device A, equipment B, equipment C is respectively: 10,20,30, the ActiveID of this IRF is that 10 (member numbers minimum member device and is elected as Master equipment, the ActiveID of IRF is member's numbering of Master equipment), the port id that device A, equipment B, equipment C connect intermediate equipment is respectively 100,200,300; When initial, the port of device A, equipment B, equipment C connection intermediate equipment is chooses port.
The disposition that IRF does not divide:
In the time that IRF does not divide, device A is Master equipment, and equipment B and equipment C are Slave equipment.System information in the member device of device A, equipment B, equipment C is identical (identical with IRF facility information) all, and only ports having information is not identical.Wherein,
The member device information of device A is: the system information of device A (LACP priority is 1, IRF priority is that 1, IRF member device number is 3, the ActiveID of IRF be 10) is connected the port information (port id is 100) of intermediate equipment with device A.The member device information of equipment B is: the system information of equipment B (LACP priority is 1, IRF priority is that 1, IRF member device number is 3, the ActiveID of IRF be 10) is connected the port information (port id is 200) of intermediate equipment with equipment B.The member device information of equipment C is: the system information of equipment C (LACP priority is 1, IRF priority is that 1, IRF member device number is 3, the ActiveID of IRF be 10) is connected the port information (port id is 300) of intermediate equipment with equipment C.
Device A, equipment B, equipment C all can send to intermediate equipment by the member device information of self,, and determined whether the member device information announcement receiving to other member device according to the odds of the optimum member device information of the member device information receiving and current record by intermediate equipment.Suppose that intermediate equipment receives the member device information that receives successively device A, equipment B, equipment C transmission successively,,
Intermediate equipment receives after the LACP protocol massages of member device information of the Portable device A of device A transmission, not yet record optimal device information because intermediate equipment is current, therefore the member device information that is device A by optimal device information updating, simultaneously by the member device information announcement of device A to equipment B and equipment C.
When equipment B receives the member device information of device A, because device A is Master equipment, equipment B is Slave equipment, therefore the member device information of device A is sent to device A; Device A judgement determine that the member device information receiving is better than the member device information of equipment B self and the member device information that receives in system information in the member device information of the system information that comprises and equipment B identical, thereby keep equipment B to connect the selected state of intermediate equipment, can not close all service ports of self.
Same reason, when equipment C receives the member device information of device A, because device A is Master equipment, equipment C is Slave equipment, therefore the member device information of device A is sent to device A; Device A judgement determine that the member device information receiving is better than the member device information of equipment C self and the member device information that receives in system information in the member device information of the system information that comprises and equipment C identical, thereby keep equipment C to connect the selected state of intermediate equipment, can not close all service ports of self.
Intermediate equipment receives after the LACP protocol massages of member device information of the Portable device B of equipment B transmission, because the intermediate equipment current record optimal device information member device information of device A (now for) is better than the member device information of equipment B, therefore abandon the member device information of equipment B.
Intermediate equipment receives after the LACP protocol massages of member device information of the Portable device C of equipment C transmission, because the intermediate equipment current record optimal device information member device information of device A (now for) is better than the member device information of equipment B, therefore abandon the member device information of equipment B.
And device A is not received the member device information of equipment B and equipment C all the time, therefore its port that connects intermediate equipment is always selected state, and service port also can not be closed.Again because equipment B and equipment C receive after the member device information of device A of intermediate equipment notice, device A is all identical with the system information of device A by relatively determining the system information of equipment B, equipment C as Master equipment, therefore, also the port that keeps equipment B, equipment C to connect intermediate equipment is always selected state, and service port also can not be closed.Finally, all service ports in IRF are not all closed, and IRF normally moves.
Can find out, according to method shown in Fig. 6, when IRF does not divide, IRF normally moves, and the traffic forwarding of IRF is unaffected.
The disposition of IRF division:
IRF link between device A and equipment B disconnects and causes IRF to be split into IRF1 (being made up of device A, device A is Master equipment) and IRF2 (formed by equipment B and equipment C, equipment B is Master equipment, equipment C is Slave equipment) after, the LACP priority of IRF1 and IRF2 and the LACP priority of original IRF are consistent, and are still 1; The priority of IRF1 and IRF2 and the priority of original IRF are consistent, and are also 1; The member device number of IRF1 is that 1, ActiveID is 10; The member device number of IRF2 is that 2, ActiveID is 20.
Therefore, in the system information that the member device packets of information of device A contains, LACP priority, IRF priority, member device number and ActiveID are respectively 1,1,1,10, and in the port information that the member device packets of information of device A contains, port id is 100.In the system information that the member device packets of information of equipment B contains, LACP priority, IRF priority, member device number and ActiveID are respectively 1,1,2,20, and in the port information that the member device packets of information of equipment B contains, port id is 200.In the system information that the member device packets of information of equipment C contains, LACP priority, IRF priority, member device number and ActiveID are respectively 1,1,2,20, and in the port information that the member device packets of information of equipment C contains, port id is 300.
Device A, equipment B and equipment C all can send to intermediate equipment the member device information of self, and determined whether the member device information announcement receiving to other member device according to the odds of the optimum member device information of the member device information receiving and current record by intermediate equipment, suppose that intermediate equipment receives the member device information of device A, equipment B, equipment C transmission successively,
In the time that intermediate equipment receives the member device information of device A, not yet record optimal device information because intermediate equipment is current, therefore the member device information that is device A by the optimum member device information updating of current record, and by the member device information announcement of device A to equipment B and equipment C.When equipment B receives the member device information of device A, due to the Master equipment from as IRF2, therefore by comparing member device information quality, determine that the member device information of self is better than the member device information of device A, therefore keep self connecting the selected state of the port of intermediate equipment.When equipment C receives the member device information of device A, because of the Master equipment that equipment B is IRF2, the Slave equipment that equipment C is IRF2, therefore sends to equipment B by the member device information of device A; Equipment B is by the quality of the member device information of the member device information that relatively receives and equipment C, determines the member device information that the member device information of equipment C is better than receiving, and therefore keeps equipment C to connect the selected state of the port of intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment B, the quality of the optimum member device information (being now the member device information of device A) of the member device information of compare facilities B and intermediate equipment current record, determine that the member device information of equipment B is better than the optimum member device information of intermediate equipment current record, therefore, the member device information that is equipment B by the optimum member device information updating of intermediate equipment current record, and by the member device information announcement of equipment B to device A and equipment C.When device A receives the member device information of equipment B, because certainly as Master equipment, therefore by comparing member device information quality, determine that the member device information of self is inferior to the member device information of equipment B, therefore the port that self connects intermediate equipment is set to not selected state, because only comprising device A and device A, IRF1 connects the not non-port of choosing of port of intermediate equipment again, therefore all service ports outside the port of closing device A connection intermediate equipment.When equipment C receives the member device information of equipment B, because the Master equipment that equipment B is IRF2, the Slave equipment that equipment C is IRF2, therefore sends to equipment B by the member device information of equipment B; Equipment B is by the quality of the member device information of the member device information that relatively receives and equipment C, determine that the system information that the member device information that receives is better than the member device information of equipment C and the member device packets of information that receives contains is identical with the system information of equipment C, therefore keep the selected state of the port of equipment C connection intermediate equipment.
In the time that intermediate equipment receives the member device information of equipment C, the quality of the optimum member device information (being now the member device information of equipment B) of the member device information of compare facilities C and intermediate equipment current record, determine that the member device information of equipment C is identical with the optimum member device information of intermediate equipment current record, therefore, do not carry out member device notice.
Can find out, in method shown in Fig. 5, intermediate equipment is by comparing the optimum member device information of the member device information receiving and current record, only in the time that the member device information receiving is better than the optimum member device information of current record, just proceed member device information announcement, with respect to method shown in Fig. 3, can reduce bandwidth resources waste.And according to method shown in Fig. 6, after IRF division, in the IRF1 being made up of device A, all service ports are all closed, IRF1 does not bear data traffic and forwards.In the IRF2 being made up of equipment B and equipment C, all service ports are not all closed, and therefore IRF2 bears data traffic forwarding.
In the embodiment of the present invention shown in Fig. 6, can utilize virtual SYSTEM-ID-MAC to replace the SYSTEM-ID-MAC field in LACP protocol massages, carry the part field of the system information comprising in member device information with virtual SYSTEM-ID-MAC, for example, priority, member device number and the ActiveID of the OUI of company mark, Field Number, the current place IRF of member device, specifically as shown in Figure 7, wherein
In virtual SYSTEM-ID-MAC field, high-order 25 to 48 are consistent with 25 to 48 of high positions for IRF bridge MAC Address, are the peculiar mark (OUI of company mark) of company.
Next 15 to 24 is Field Number (DomainID), under default situations, be consistent to 24 with 15 of IRF bridge MAC Address, but during if there is multiple IRF or when virtual SYSTEM-ID-MAC conflicts with physical device bridge MAC, user can number DomainID to ensure uniqueness by configuration modification.
Ensuing 13 to 14 for after IRF division, the precedence information of the current place IRF of member device, span is 0 to 3, wherein 0 to 2 can use, 3 do to retain temporarily, in one embodiment of the invention, it is worth more small tenon, and to know priority higher.
Ensuing 7 to 12 member device numbers that have for dividing the rear current place IRF of member device, maximum can represent 64 equipment, in one embodiment of the invention, its value is less shows that the member device quantity that the current place IRF of member device has is more, for example: in the time having 63 member devices, this value is 1, and in the time only having 1 member device, this value is 63.
1 to 6 numbering ActiveID (being also the ActiveID of the Master equipment of the current place IRF of member device) for the current place IRF of member device after division of lowest order.
It should be noted that, the embodiment of the present invention shown in Fig. 6 is actually the thought that realizes based on LACP MAD, in reality realizes, each attribute information that the link aggregations such as the Operational Key that needs to ensure IRF equipment and intermediate equipment by configuration and attribute configuration are relevant is consistent.
And according to LACP agreement, IRF is as with reference to end, after being provided with and choosing port, can also be by respectively choosing port to choose notice to intermediate equipment transmit port, make intermediate equipment the port of choosing of self to be set according to the port of choosing of IRF side.Wherein, the system information in the member device information of respectively choosing port to have respectively to choose in identical attribute information and intermediate equipment each member device that port connects in intermediate equipment also will be consistent, this with prior art to realize principle identical.
In prior art, GOLD (Generic OnLine Diagnostics, gpio line diagnosis), by carry out diagnostic test example on equipment, finds hardware fault, and carries out problem report.The hardware fault that GOLD checks mainly comprises: whether port, internal memory, chip, connection, forward-path and control path be normal etc.
In IRF, be conventionally provided with GOLD module, be used for detecting in IRF, whether to occur hardware fault.In actual applications, in the time that data retransmission problem appears in IRF, GOLD module can detect this problem and carry out problem report.In embodiments of the present invention, when after IRF division, the IRF that continues to bear traffic forwarding, if there is data retransmission problem, can make self no longer to continue to bear traffic forwarding by the mode that reduces IRF priority.
According to above-mentioned Fig. 3, 4, 5, method shown in 6, the LACP priority of each member device and the LACP priority of original IRF is identical and can not change before and after IRF division, therefore, after IRF division, the priority of certain IRF is less, in the time that the member device information of the member device information of this IRF and other IRF is compared, the facility information of the member device of this IRF can not be better than the member device information of described other IRF, therefore, all of the port in this IRF except the port of connection intermediate equipment will be closed, this also just means that this IRF can bearer traffic.
Therefore, in the present invention, in the time there is data retransmission fault in IRF, can make self no longer to continue to bear traffic forwarding by the mode that reduces IRF priority, concrete methods of realizing is: know when this member device place IRF exists data retransmission fault, this member device information exchange is crossed when connecting the port of described intermediate equipment and sending to described intermediate equipment, and the priority of the current place IRF of this member device that in this member device information, system information comprises is set to minimum priority value.
Wherein, know that the current place IRF of this member device exists the method for data retransmission fault to be: the GOLD module that receives this member device place IRF detects this IRF and has the data retransmission signalling trouble sending after data retransmission fault, determine that the current place IRF of this member device exists data retransmission fault.
In fact, after IRF division, if keeper finds to bear after IRF division the IRF of traffic forwarding while there is data retransmission fault, also can issue positive closing order, force the IRF just forwarding at bearer traffic to close all service ports, make it no longer bear traffic forwarding.Meanwhile, keeper can also select one in the each IRF after division, and issues pressure enable command to this IRF, forces the IRF that has closed all service ports to bear traffic forwarding.Therefore, when a member device is as the Master equipment of current place IRF, if receive the positive closing order from network management system at management interface, the all service ports except the port of connection intermediate equipment of current this member device place IRF are closed, thereby make the current place IRF of this member device no longer bear traffic forwarding; When a member device is as the Master equipment of current place IRF, the current place IRF of this member device except connecting all service ports the port of intermediate equipment all in pent situation, if receive the pressure enable command from network management system at management interface, all service ports of current this member device place IRF can be started to UP and get up, forward thereby make this member device place IRF start to bear data traffic.
Can find out, in the time that IRF exists forwarding fault, send the priority of member device information by reducing member device, can avoid this IRF to be selected to and continue the IRF that bearer traffic forwards.
