Range.
Fig. 1 is the schematic diagram of stacking splitting networking in the embodiment of the present invention.As shown in Figure 1, in the stacking splitting networking
Including the interchanger 1 and interchanger 2 being located in same stacking, and the interchanger 3 outside the stacking, wherein 1 He of interchanger
Interchanger 2 is connected with interchanger 3 respectively, and interchanger 1 and interchanger 2 are due in same stacking, also phase between them
Even.
Before stacking splitting, interchanger 1 and interchanger 2 share the same relam identifier, the relam identifier and interchanger 3
Relam identifier is different.
After stacking splitting, interchanger 1 and interchanger 2 are no longer in the same stacking, but form respectively independence
Interchanger.
However, interchanger 1 and interchanger 2 still use identical relam identifier after stacking splitting, in this way, working as interchanger
3 when receiving LSR (Link State Records, the link state records) of interchanger 1 or interchanger 2, due in LSR
Relam identifier is identical, then the situation that interchanger 3 will cause confusion when carrying out router-level topology according to the LSR.
The embodiment of the present invention can be the respective switch allocation in same stacking on the basis of the relam identifier
Outer stacking identifier, can be distinguished to the interchanger being originally in same stacking after stacking splitting.
Fig. 2 is a kind of method flow diagram for handling stacking splitting provided in an embodiment of the present invention.Although process is described below
Including the multiple operations occurred with particular order, but it should be clearly understood that these processes may include more or fewer behaviour
Make, these operations can be executed sequentially or be executed parallel, such as use parallel processor or multi-thread environment.Implement in the present invention
In example, the first interchanger and second switch can be the member device of same stacking, as shown in Figure 2, which comprises
S1: when the stacking divides, the first configuration information of itself is passed through the heap by first interchanger
It folds outer 3rd switch and is sent to the second switch, first configuration information includes at least first interchanger
First stacking identifier of the first relam identifier and first interchanger.
FSPF (Fabric Shortest Path First, optical fiber shortest path first) can be used in the embodiment of the present invention
Agreement carries out the collision detection after stacking splitting, is to have done corresponding extension on the basis of the reliable flooding mechanism of FSPF and sentenced
It is disconnected, so as to be communicated to the information of equipment each in network each other by flooding mechanism, so that each equipment can be sentenced
Whether there is stacking splitting in circuit network.After stacking splitting generation, the topological structure of the interchanger in same stacking
It can change.
As shown in Figure 1, be direct-connected between original interchanger 1 and interchanger 2, however when stacking splitting, 1 He of interchanger
It is no longer direct-connected between interchanger 2, but be indirectly connected by interchanger 3.In embodiments of the present invention, interchanger 1 can be institute
The first interchanger is stated, interchanger 2 can be the second switch, and interchanger 3 can be the 3rd switch.
First interchanger and the second switch are due to being originally in same stacking, first exchange
Machine and the second switch have identical relam identifier.In embodiments of the present invention, in order to being capable of area after stacking splitting
Divide first interchanger and the second switch, can be added respectively for first interchanger with the second switch
Identifier is uniquely stacked, in this way, the combination by relam identifier and stacking identifier can be to originally in same stacking
In different interchangers distinguish.
In stacking splitting, first interchanger can by the first configuration information of itself by the stacking outside
Three interchangers are sent to the second switch, and the first domain of first interchanger is included at least in first configuration information
First stacking identifier of identifier and first interchanger.
After 3rd switch receives first configuration information that first interchanger is sent, can by this first
Configuration information is transmitted to the second switch.
S2: first interchanger receives the second configuration information of the second switch by the 3rd switch,
Second configuration information includes at least the second relam identifier of the second switch and the second heap of the second switch
Folded identifier.
Similarly, when the stacking divides, the second switch can also lead to the second configuration information of itself
It crosses the 3rd switch to be sent at first interchanger, second configuration information includes at least the second switch
The second relam identifier and the second switch second stack identifier.
S3: when first relam identifier is identical as second relam identifier, and described first stack identifier with
When the second stacking identifier meets preset condition, the service port on first interchanger is closed.
After first interchanger receives second configuration information, it can be extracted from second configuration information
Second relam identifier and described second stacks identifier out.First interchanger can mark the second domain extracted
The first relam identifier for knowing symbol with itself compares, and the first stacking that described second stacks identifier and itself is identified
Symbol compares.When second relam identifier is identical as first relam identifier, then illustrate first interchanger with
The second switch is originally in same stacking.
It in embodiments of the present invention, can in order to avoid 3rd switch when carrying out router-level topology the case where confusion reigned
One in the first interchanger and second switch to be closed.Specifically, the embodiment of the present invention can will stack identifier compared with
Small interchanger is closed.In this way, can then be considered as institute when described first stacks identifier and be greater than the second stacking identifier
It states the first stacking identifier and the second stacking identifier meets preset condition, so as to will be on first interchanger
Service port is closed.When 3rd switch is when carrying out router-level topology, the routing of second switch can be only obtained, thus will not
The case where confusion reigned.
It should be noted that can also equally be carried out in the second switch above-mentioned to relam identifier and stacking knowledge
The process that Fu do not extracted and compare.After two interchangers receive mutual configuration information, it can carry out respectively pair
Relam identifier and the extraction and comparison process for stacking identifier thereby may be ensured that only have the industry of an interchanger after comparison
Business port is in running order.
More detailed elaboration is carried out to technical solution of the present invention below in conjunction with concrete application scene:
Currently, FC group of switches at Fabric network in mainly using FSPF (shortest path is preferred) agreement come dynamic
Generate FC routing.FSPF Routing Protocol is the agreement that Path selection is carried out according to link state, it can continue tracking network
The link-state information of all interchangers in network, the link-state information of all interchangers constitute LSDB (Link State
DataBase, link state database), interchanger calculates the smallest road of other respective switch into network according to LSDB
Diameter, to be generated to the FSPF routing of other respective switch.
The LSR of one interchanger completely describes the link state of the interchanger Yu other direct-connected interchangers.Each
Interchanger is responsible for safeguarding and issuing the LSR of own.Every LSR can be by Link-State ID (link state identification
Code) carry out unique identification, in a stacking, all interchangers in the stacking share the same Domain ID (domain identifier
Symbol).
In a concrete application scene, when the stacking splitting, first interchanger can update the LSR of itself,
It include the first configuration information of the first interchanger in LSR.
Table 1 is the schematic table of the LSR Header of the first interchanger in the embodiment of the present invention.
Table 1
As shown in table 1, the Domain ID in the LSR of the first interchanger can fill in itself affiliated relam identifier stacked,
And itself stacking identifier can be then filled in the Reserved that length is 4 bytes.The stacking identifier can be place
The number of respective switch in the same stacking, the number do not repeat in same stacking.
For example, as shown in Figure 1, the relam identifier of interchanger 1 and interchanger 2 can be X, and interchanger 1 is in a stack
Number be 1, the number of interchanger 2 in a stack is 2, then 1 can serve as the stacking identifier of interchanger 1,2 can be with
Stacking identifier as interchanger 2.Before stacking splitting, interchanger 1 and interchanger 2 respectively by respective physical port with
Interchanger 3 communicates.In this way, neighbor state, interchanger 2 and interchanger 3 after stacking splitting, between interchanger 1 and interchanger 3
Between neighbor state be still to completely abut against FULL.
Therefore, after stacking splitting, after LSR of the interchanger 1 to itself is updated, updated LSR can be sealed
Loaded on the configuration information 1 in link state update packet 1, in the updated LSR of interchanger 1 including interchanger 1, include: in the configuration information 1
Relam identifier X and stacking identifier 1.At this point, interchanger 2 is not direct-connected with interchanger 1 after due to stacking splitting, and only exchange
Machine 3 and interchanger 1 are direct-connected, then the link state update packet 1 then can be sent to interchanger 3 by interchanger 1, by interchanger 3 by the LSU
Message 1 floods to interchanger 2.
Similarly, it after the interchanger 2 in the same stacking can also be updated the LSR of itself, can will update
LSR afterwards is packaged in link state update packet 2, includes the configuration information 2 of interchanger 2, the configuration information in the updated LSR of interchanger 2
It include: relam identifier X and stacking identifier 2 in 2.At this point, interchanger 1 is not direct-connected with interchanger 2 after due to stacking splitting, and
Only interchanger 3 and interchanger 2 is direct-connected, then the link state update packet 2 can be then sent at interchanger 3 by interchanger 2, by exchanging
Machine 3 floods the link state update packet 2 to interchanger 1.
Interchanger 1 can analyze the LSR in the link state update packet 2 after receiving link state update packet 2.Likewise, handing over
2 are changed planes after receiving link state update packet 1, the LSR in the link state update packet 1 can be analyzed.For example, can analyze in LSR
Checksum, LSR Type information it is whether correct, whether LSR Age reaches Max Age, minimum receive interval whether time-out
Deng.These conventional analysis means are existing means in the prior art, and the present invention does not repeat them here this.
In embodiments of the present invention, relam identifier and stacking identifier can be analyzed with emphasis.
For example, interchanger 1 can extract configuration information 2 from the LSR that LSU2 message carries.Interchanger 1 can will extract
Configuration information 2 out and the configuration information 1 of itself compare.Due to domain identifier X and configuration information 1 in configuration information 2
In domain identifier X it is identical, and the domain identifier 2 in configuration information 2 is greater than the domain identifier 1 in configuration information 1, according to default
Rule is (for example, preset rules are that will stack the smallest interchanger of identifier to retain, and the service port of other interchangers closes
Close), then 1 retained business port of interchanger, is not closed.
Interchanger 2 can extract configuration information 1 from the LSR that LSU1 message carries.Interchanger 1 can match what is extracted
Confidence breath 1 and the configuration information 2 of itself compare.Due to the domain identifier X in configuration information 1 and the domain in configuration information 2
Identifier X is identical, and the domain identifier 2 in configuration information 2 is greater than the domain identifier 1 in configuration information 1, according to preset rules
(for example, preset rules are that will stack the smallest interchanger of identifier to retain, and the service port of other interchangers is closed),
Then interchanger 2 closes service port.
In this way, originally the interchanger in same stacking can receive mutual configuration information, so as to incite somebody to action
The configuration information received and the configuration information of itself compare, and it is one the smallest finally can then to filter out stacking identifier
Interchanger works on, and other interchangers can then stop working, to guarantee that business datum does not repeat.In another implementation of the present invention
In example, the port trunking of interchanger 1, interchanger 2 before stacking splitting, i.e., the case where communication by aggregation port with interchanger 3
Under, the HELLO message that FSPF can be used carries out the transmission of information as configuration information.In this embodiment of the invention, hand over
Changing planes 1 can be for first interchanger, and interchanger 2 can be the second switch, and interchanger 3 can be handed over for the third
It changes planes.
Table 2 is in the embodiment of the present invention using the schematic table of the HELLO message of FSPF.
Table 2
In table 2, the Reserved field of 1 byte-sized after Recipient Domain_ID can be used to take
The stacking identifier of tape swap machine.
HELLO message can be divided into unidirectional HELLO message and two-way HELLO message, both HELLO messages can be used
In the linking relationship established between maintenance neighboring switch.Unlike, message hair is often only carried in unidirectional HELLO message
The routing address for the side of sending, and the routing address of message transmitting party and message recipient is then carried in two-way HELLO message.
Fig. 3 is the signaling process figure between the respective switch in the embodiment of the present application in polymerization networking.Specifically,
Assuming that interchanger 1 is stand-by equipment before stacking splitting, and interchanger 2 was originally main equipment, and interchanger 1, interchanger 2 are stacking
Before division and the neighbor state of interchanger 3 is FULL.So after stacking splitting, interchanger 1 can be changed into from stand-by equipment
Main equipment, then the neighbor state of interchanger 1 and interchanger 3 can become initializing Initial, and interchanger 2 is not due to changing
Become equipment state, therefore the neighbor state or FULL of interchanger 2 and interchanger 3.
In this way, the topological structure of interchanger 1 in a network changes when stacking splitting, interchanger 1 can be incited somebody to action at this time
The configuration information 1 of itself is filled into HELLO message, and unidirectional HELLO message is sent to interchanger 3, and configuration information 1 is at least
Relam identifier X and stacking identifier 1 including interchanger 1 itself.Interchanger 3 is after receiving the unidirectional HELLO message, meeting
The neighbor state of FULL is equally revised as Initial, then interchanger 3 can be to all members (interchanger 1 and the friendship of aggregation port
It changes planes and 2) replys two-way HELLO message 1, carry configuration information 1 in the two-way HELLO message 1.Interchanger 1 receives exchange
After the two-way HELLO message 1 that machine 3 is replied, the configuration information 1 that itself is carried in the two-way HELLO message 1 is analyzed, at this time
Neighbor state between interchanger 1 and interchanger 3 can be revised as database and exchange DB_Exchange state, then may be used
It is synchronous to carry out LSDB initialization with interchanger 3, and by the neighbor state between interchanger 1 and interchanger 3 after synchronously completing
Finally it is revised as FULL.
And the configuration information 1 for carrying interchanger 1 that interchanger 3 is sent is being received as the interchanger of main equipment 2
When two-way HELLO message 1, the configuration information 1 of interchanger 1 was not recorded in interchanger 2 at this time, then will record the configuration information
1.Two-way HELLO message 2 can be sent to interchanger 3, and the configuration information 2 of interchanger 2 is carried in the two-way HELLO message 2, is matched
Confidence breath 2 may include the relam identifier X and stacking identifier 2 of interchanger 2.The two-way HELLO message 2 in turn can be by interchanger
3, by processing, generate the two-way HELLO message 3 for carrying configuration information 2, and interchanger 3 can be to all members (exchange of aggregation port
Machine 1 and interchanger 2) send the two-way HELLO message 3.
After interchanger 1 receives two-way HELLO message 3, configuration information 2 was not recorded in interchanger 1 at this time, then can be remembered
Record configuration information 2.
After interchanger 2 receives two-way HELLO message 3, find to carry matching for itself in the two-way HELLO message 3
Confidence breath 2, interchanger 2 just no longer replys message to interchanger 3 at this time.
In addition, interchanger 1 can send to interchanger 3 carry configuration information 1 again in response to the two-way HELLO message 3
Two-way HELLO message 4.
Interchanger 3, by processing, generates the two-way HELLO for carrying configuration information 1 after receiving two-way HELLO message 4
Message 5, interchanger 3 can send the two-way HELLO message 5 to all members (interchanger 1 and interchanger 2) of aggregation port.
After interchanger 1 receives two-way HELLO message 5, it is found that the configuration information 1 carried in the two-way HELLO message 5 is
The configuration information of itself, then then no longer responding the two-way HELLO message 5.
After interchanger 2 receives two-way HELLO message 5, the configuration information 1 carried in the two-way HELLO message 5 is found
It is crossed by self record, then no longer makes reply to interchanger 3 at this time.
In this way, originally the main equipment (interchanger 2) in same stacking and stand-by equipment (interchanger 1) receive that
This configuration information.Since the domain identifier X in configuration information 1 is identical as the domain identifier X in configuration information 2, and match confidence
Domain identifier 2 in breath 2 is greater than the domain identifier 1 in configuration information 1, according to preset rules (for example, preset rules are that will stack
The smallest interchanger of identifier retains, and the service port of other interchangers is closed), then interchanger 2 closes service port,
1 retained business port of interchanger is not closed.
It works in this way, may finally filter out and stack the smallest interchanger of identifier, and other interchangers are then
It can stop working, to guarantee that business datum does not repeat.
Therefore a kind of method for handling stacking splitting provided in an embodiment of the present invention, pass through the base in relam identifier
It attached stacking identifier on plinth, so as to distinguish each equipment after stacking splitting.In addition, originally in same
Configuration information of the respective switch by transmission mutually comprising respective relam identifier and stacking identifier in stacking, so as to
So that the configuration information for other the available interchangers of respective switch being in same stacking originally.Further, lead to
The comparison of different configuration informations is crossed, and according to the relationship of comparing result and preset condition, so as to which script is in same a pile
The service port of an interchanger in folded retains, and the service port of other interchangers is closed, so as to avoid information
The confusion of transmission guarantees correctly to be forwarded according to the routing that FSPF (shortest path is preferred) generates.
Further, by the comparison of the configuration information of distinct device, and according to the relationship of comparing result and preset condition,
The equipment that stacking splitting occurs is performed corresponding processing, so that the confusion for avoiding information from transmitting, guarantees according to shortest path
The routing that diameter preferably generates correctly is forwarded.
