Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical scheme in the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of protection of the invention.
Fig. 1 is the schematic diagram of stacking splitting networking in the embodiment of the present invention.As shown in Figure 1, described stacking splitting networking includes being arranged in same stacking switch 1 and switch 2, and it is positioned at this stacking outer switch 3, wherein, switch 1 is connected with switch 3 respectively with switch 2, switch 1 and switch 2 due to be in same stacking in, be therefore also connected between them.
When, before stacking splitting, switch 1 and switch 2 share same relam identifier, and this relam identifier is different from the relam identifier of switch 3.
When after stacking splitting, switch 1 and switch 2 be no longer on same stacking in, but form respectively stand alone exchange.
But, after stacking splitting, switch 1 and switch 2 still use identical relam identifier, so, when switch 3 receives the LSR (LinkStateRecords of switch 1 or switch 2, link state records) time, owing to the relam identifier in LSR is identical, then switch 3 arises that the situation of confusion when carrying out router-level topology according to this LSR.
The embodiment of the present invention can on the basis of described relam identifier, for same stacking in respective switch allocation outside stacking identifier, with after stacking splitting can be originally in same stacking in switch make a distinction.
A kind of method flow diagram processing stacking splitting that Fig. 2 provides for the embodiment of the present invention.Although multiple operations that flow process include with particular order occur are described below, but it should be clearly understood that these processes can include more or less of operation, these operations can sequentially perform or executed in parallel, for instance uses parallel processor or multi-thread environment.In embodiments of the present invention, the first switch and the second switch can be same stacking member device, as in figure 2 it is shown, described method includes:
S1: when described stacking generation division, the first configuration information of self is sent to described second switch by described first switch by described stacking the 3rd outer switch, and described first configuration information at least includes the first relam identifier of described first switch and the first stacking identifier of described first switch.
The embodiment of the present invention can use FSPF (FabricShortestPathFirst, optical fiber SPF) agreement carries out the collision detection after stacking splitting, it is done corresponding extension and judgement on the basis of the reliable flooding mechanism of FSPF, it is thus possible to the information of each equipment in network conveyed to each other by flooding mechanism, so that each equipment can interpolate that in network whether occur in that stacking splitting.After stacking splitting occurs, be in same stacking in the topological structure of switch can change.
As it is shown in figure 1, be originally direct-connected between switch 1 and switch 2, but when stacking splitting, no longer direct-connected between switch 1 and switch 2, but be indirectly connected to by switch 3.In embodiments of the present invention, switch 1 can be described first switch, and switch 2 can be described second switch, and switch 3 can be described 3rd switch.
Described first switch and described second switch due to be originally in same stacking in, therefore described first switch and described second switch possess identical relam identifier.In embodiments of the present invention, in order to described first switch and described second switch can be distinguished after stacking splitting, can be that described first switch adds unique stacking identifier respectively with described second switch, so, by the combination of relam identifier and stacking identifier just can be originally in same stacking in different switches make a distinction.
When stacking splitting, the first configuration information of self can be sent to described second switch by described first switch by described stacking the 3rd outer switch, at least includes the first relam identifier of described first switch and the first stacking identifier of described first switch in described first configuration information.
After the 3rd switch receives described first configuration information that described first switch is sent, it is possible to this first configuration information is transmitted to described second switch.
S2: described first switch receives the second configuration information of described second switch by described 3rd switch, and described second configuration information at least includes the second relam identifier of described second switch and the second stacking identifier of described second switch.
Similarly, when described stacking generation division, the second configuration information of self also can be sent to described first switch place by described second switch by described 3rd switch, and described second configuration information at least includes the second relam identifier of described second switch and the second stacking identifier of described second switch.
S3: when described first relam identifier is identical with described second relam identifier, and when described first stacking identifier meets pre-conditioned with described second stacking identifier, close the service port on described first switch.
After described first switch receives described second configuration information, it is possible to extract described second relam identifier and described second stacking identifier from described second configuration information.The second relam identifier extracted just can be contrasted by described first switch with the first relam identifier of self, and is contrasted with the first stacking identifier of self by described second stacking identifier.When described second relam identifier is identical with described first relam identifier, then illustrate described first switch and described second switch be originally be in same stacking in.
In embodiments of the present invention, in order to avoid the 3rd switch situation of confusion reigned when carrying out router-level topology, it is possible to by a closedown in the first switch and the second switch.Specifically, switch less for stacking identifier can be closed by the embodiment of the present invention.So, when described first stacking identifier is more than described second stacking identifier, then can be considered as described first stacking identifier and meet pre-conditioned with described second stacking identifier, such that it is able to the service port on described first switch is closed.When the 3rd switch is when carrying out router-level topology, only can draw the route of the second switch, from the situation without confusion reigned.
It should be noted that the above-mentioned process that relam identifier and stacking identifier are extracted and contrasted can also be carried out on described second switch equally.After two switches receive configuration information each other, it is possible to carry out the extraction to relam identifier and stacking identifier and comparison process respectively, thereby may be ensured that the service port only having a switch after contrast is in running order.
Below in conjunction with concrete application scenarios, technical scheme is carried out more detailed elaboration:
At present, FSPF (shortest path is preferred) agreement is mainly used dynamically to generate FC route in the Fabric network of FC switch composition.FSPF Routing Protocol is an agreement carrying out Path selection according to Link State, it can continue the link-state information of all switches in tracking network, the link-state information of all switches constitutes LSDB (LinkStateDataBase, LSD), switch calculates the minimum path of other respective switch in network according to LSDB, thus being generated to the FSPF route of other respective switch.
The Link State describing this switch and other direct-connected switches complete for LSR of one switch.Each switch is responsible for safeguarding and issuing the LSR of its own.Every LSR uniquely can be identified by Link-StateID (Link State identity code), in stacking at one, be in this stacking in all switches share same DomainID (relam identifier).
In a concrete application scenarios, when described stacking splitting, described first switch can update self LSR, LSR and include the first configuration information of the first switch.
Table 1 is the signal table of the LSRHeader of the first switch in the embodiment of the present invention.
Table 1
As shown in table 1, the DomainID in the LSR of the first switch can fill in relam identifier stacking belonging to self, then can fill the stacking identifier of self in the Reserved that length is 4 bytes.Described stacking identifier can be in the numbering of same stacking middle respective switch, this numbering same stacking in do not repeat.
Such as, as it is shown in figure 1, the relam identifier of switch 1 and switch 2 can be X, and switch 1 in a stack be numbered 1, switch 2 in a stack be numbered 2, then 1 can serve as the stacking identifier of switch 1, and 2 can the stacking identifier of in return machine 2.Before stacking splitting, switch 1 communicates with switch 3 respectively through respective physical port with switch 2.So, after stacking splitting, the neighbor state between switch 1 and switch 3, the neighbor state between switch 2 and switch 3 are still and completely abut against FULL.
Therefore, after stacking splitting, after the LSR of self is updated by switch 1, it is possible to the LSR after updating is packaged in link state update packet 1, LSR after switch 1 renewal includes the configuration information 1 of switch 1, and this configuration information 1 includes: relam identifier X and stacking identifier 1.Now, after stacking splitting, switch 2 is not direct-connected with switch 1, and it is direct-connected with switch 1 to only have switch 3, then this link state update packet 1 then can be sent to switch 3 by switch 1, switch 3 flood this link state update packet 1 to switch 2.
Similarly, same stacking in switch 2 LSR of self can also be updated after, can being packaged in link state update packet 2 by the LSR after updating, the LSR after switch 2 renewal includes the configuration information 2 of switch 2, and this configuration information 2 includes: relam identifier X and stacking identifier 2.Now, after stacking splitting, switch 1 is not direct-connected with switch 2, and it is direct-connected with switch 2 to only have switch 3, then this link state update packet 2 then can be sent to switch 3 place by switch 2, switch 3 flood this link state update packet 2 to switch 1..
Switch 1 is after receiving link state update packet 2, it is possible to the LSR in described link state update packet 2 is analyzed.Same, switch 2 is after receiving link state update packet 1, it is possible to the LSR in described link state update packet 1 is analyzed.For example, it is possible to whether Checksum, LSRType information analyzed in LSR is correct, whether LSRAge reaches MaxAge, minimum accepts interval whether time-out etc..The analysis means of these routines is existing means of the prior art, and this is not repeated by the present invention.
In embodiments of the present invention, it is possible to relam identifier and stacking identifier are analyzed by emphasis.
Such as, switch 1 can extract configuration information 2 from the LSR that LSU2 message carries.The configuration information 2 extracted can be contrasted by switch 1 with the configuration information 1 of self.Due to, territory indications X in configuration information 2 is identical with the territory indications X in configuration information 1, and the territory indications 2 in configuration information 2 is more than the territory indications 1 in configuration information 1, according to preset rules (such as, preset rules is retained by switch minimum for stacking identifier, and the service port of other switch is closed), then switch 1 retained business port, does not close.
Switch 2 can extract configuration information 1 from the LSR that LSU1 message carries.The configuration information 1 extracted can be contrasted by switch 1 with the configuration information 2 of self.Due to, territory indications X in configuration information 1 is identical with the territory indications X in configuration information 2, and the territory indications 2 in configuration information 2 is more than the territory indications 1 in configuration information 1, according to preset rules (such as, preset rules is retained by switch minimum for stacking identifier, and the service port of other switch is closed), then switch 2 closes service port.
So, originally be in same stacking in switch all can receive configuration information each other, such that it is able to the configuration information received is contrasted with the configuration information of self, a switch that is final then that can filter out stacking identifier minimum works on, other switches then can quit work, to ensure that business datum does not repeat.In an alternative embodiment of the invention, namely the port trunking of switch 1, switch 2 before stacking splitting, when communicating with switch 3 by aggregation port, it is possible to use the HELLO message of FSPF carries out the transmission of information as configuration information.In this embodiment of the invention, switch 1 can be described first switch, and switch 2 can be described second switch, and switch 3 can be described 3rd switch.
Table 2 is the signal table of the HELLO message using FSPF in the embodiment of the present invention.
Table 2
In table 2, the Reserved field of 1 byte-sized after RecipientDomain_ID can be used to carry the stacking identifier of switch.
HELLO message can be divided into unidirectional HELLO message and two-way HELLO message, and both HELLO message may be incorporated for the linking relationship set up and safeguard between neighboring switch.The difference is that, unidirectional HELLO message often only carries the routing address of message transmitting party, two-way HELLO message then carries message transmitting party and the routing address of message recipient.
Fig. 3 is the signaling process figure being between the respective switch in polymerization networking in the embodiment of the present application.Specifically, it is assumed that switch 1 is stand-by equipment before stacking splitting, and switch 2 was originally main equipment, switch 1, switch 2 are FULL with the neighbor state of switch 3 before stacking splitting.So after stacking splitting, switch 1 can be changed into main equipment from stand-by equipment, so switch 1 can become initializing Initial with the neighbor state of switch 3, and switch 2 is not owing to changing equipment state, therefore the neighbor state of switch 2 and switch 3 or FULL.
So, when stacking splitting, switch 1 topological structure in a network changes, now the configuration information 1 of self can be filled to HELLO message by switch 1, and sending unidirectional HELLO message to switch 3, configuration information 1 at least includes relam identifier X and the stacking identifier 1 of switch 1 self.Switch 3 is after receiving this unidirectional HELLO message, the neighbor state of FULL can be revised as Initial equally, then switch 3 can reply two-way HELLO message 1 to all members (switch 1 and switch 2) of aggregation port, carries configuration information 1 in this two-way HELLO message 1.After switch 1 receives the two-way HELLO message 1 that switch 3 is replied, analyze the configuration information 1 carrying self in this two-way HELLO message 1, now just the neighbor state between switch 1 and switch 3 can be revised as data base and exchange DB_Exchange state, then can carry out LSDB with switch 3 and initialize Tong Bu, and after synchronously completing, the neighbor state between switch 1 and switch 3 is finally revised as FULL.
And as the switch 2 of main equipment when receiving the two-way HELLO message 1 of the configuration information 1 carrying switch 1 that switch 3 is sent, switch 2 did not now record the configuration information 1 of switch 1, then can record this configuration information 1.Can sending two-way HELLO message 2 to switch 3, carry the configuration information 2 of switch 2 in this two-way HELLO message 2, configuration information 2 can include relam identifier X and the stacking identifier 2 of switch 2.This two-way HELLO message 2 and then by switch 3 through processing, can generate and carry the two-way HELLO message 3 of configuration information 2, switch 3 can send this two-way HELLO message 3 to all members (switch 1 and switch 2) of aggregation port.
After switch 1 receives two-way HELLO message 3, now switch 1 did not record configuration information 2, then can recording configuration information 2.
After switch 2 receives two-way HELLO message 3, it has been found that carrying the configuration information 2 of self in this two-way HELLO message 3, now switch 2 just no longer replys message to switch 3.
It addition, switch 1 in response to this two-way HELLO message 3, can send the two-way HELLO message 4 carrying configuration information 1 again to switch 3.
Switch 3, after receiving two-way HELLO message 4, through processing, generates the two-way HELLO message 5 carrying configuration information 1, and switch 3 can send this two-way HELLO message 5 to all members (switch 1 and switch 2) of aggregation port.
After switch 1 receives two-way HELLO message 5, it has been found that the configuration information 1 carried in this two-way HELLO message 5 is the configuration information of self, then then no longer respond this two-way HELLO message 5.
After switch 2 receives two-way HELLO message 5, it has been found that the configuration information 1 carried in this two-way HELLO message 5 is crossed by self record, now then no longer makes reply to switch 3.
So, be originally in same stacking in main equipment (switch 2) and stand-by equipment (switch 1) all receive configuration information each other.Owing to the territory indications X in configuration information 1 is identical with the territory indications X in configuration information 2, and the territory indications 2 in configuration information 2 is more than the territory indications 1 in configuration information 1, according to preset rules (such as, preset rules is retained by switch minimum for stacking identifier, and the service port of other switch is closed), then switch 2 closes service port, and switch 1 retained business port is not closed.
So, the switch that may finally filter out stacking identifier minimum works on, and other switches then can quit work, to ensure that business datum does not repeat.
Therefore, a kind of method processing stacking splitting that the embodiment of the present invention provides, by addition of stacking identifier, such that it is able to made a distinction by each equipment after stacking splitting on the basis of relam identifier.It addition, be originally in same stacking in respective switch comprise respective relam identifier and the configuration information of stacking identifier by sending mutually so that be originally in same stacking in respective switch all can obtain the configuration information of other switches.Further, contrast by different configuration informations, and according to comparing result and pre-conditioned relation, such that it is able to by be originally in same stacking in the service port of a switch retain, and the service port of other switches is closed, such that it is able to avoid the confusion that information is transmitted, it is ensured that correct forwarding can be carried out according to the route that FSPF (shortest path is preferred) generates.
Further, by the contrast of the configuration information of distinct device, and according to comparing result and pre-conditioned relation, the equipment that stacking splitting occurs is processed accordingly, thus avoiding the confusion that information is transmitted, it is ensured that correct forwarding can be carried out according to the route that shortest path preferably generates.
