Step 2, host node constructs the 3rd Fast-Hello messages respectively to preset the alternative source MAC of the second quantity, And each 3rd Fast-Hello messages are sent successively.
For example, when the value of default second quantity is 8, then host node can construct the 3rd with alternative source MAC 1 respectively Fast-Hello messages 1, the 3rd Fast-Hello messages 2 are constructed with alternative source MAC 2, constructed with alternative source MAC 3 3rd Fast-Hello messages 3, the 3rd Fast-Hello messages 4 are constructed with alternative source MAC 4, with alternative source MAC 5 The 3rd Fast-Hello messages 5 are constructed, the 3rd Fast-Hello messages 6 are constructed with alternative source MAC 6, with alternate source MAC Location 7 constructs the 3rd Fast-Hello messages 7, and the 3rd Fast-Hello messages 8 are constructed with alternative source MAC 8.Further, Host node sends the 3rd Fast-Hello messages 1, the 3rd Fast-Hello messages 2, the 3rd Fast-Hello messages 3, successively Three Fast-Hello messages 4, the 3rd Fast-Hello messages 5, the 3rd Fast-Hello messages 6, the 3rd Fast-Hello messages 7th, the 3rd Fast-Hello messages 8.
Based on the form of the Fast-Hello messages shown in above-mentioned table 1, for the 3rd Fast-Hello messages, its AGG_ The value of HASH_MODE fields is designated identification (such as 2).Reported for the 3rd Fast-Hello constructed with alternative source MAC 1 Text 1, its source MAC is alternative source MAC 1, for the 3rd Fast-Hello messages constructed with alternative source MAC 2 2, its source MAC is alternative source MAC 2, and by that analogy, the source MAC of other 3rd Fast-Hello messages is no longer Repeat in detail.It is identical with the value of prior art for the value of other fields, it will not be repeated here.
Step 3, transmission node is after the 3rd Fast-Hello messages are received, if this transmission node does not pass through polymeric chain Road receives the 3rd Fast-Hello messages, then directly forwards the 3rd Fast-Hello messages.If this transmission node passes through poly- Close link and receive the 3rd Fast-Hello messages, then this transmission node forwards the 3rd Fast-Hello messages, and obtain this The alternative source MAC carried in three Fast-Hello messages, and determine to receive the 3rd Fast-Hello on this transmission node The physical port of message.
When transmission node receives the 3rd Fast-Hello messages by aggregated links, when in the contingency table of transmission node When record has the corresponding relation between the alternative source MAC currently obtained and the physical port currently determined, if contingency table In physical port corresponding to the alternative source MAC be the physical port that currently determines, then do not update contingency table；If contingency table In physical port corresponding to the alternative source MAC be not the physical port currently determined, then by alternate source MAC in contingency table Physical port corresponding to address is updated to the physical port currently determined；It is alternative when not recording this in the contingency table of transmission node During corresponding relation between source MAC and the physical port currently determined, it is standby in the contingency table of this transmission node to record this The corresponding relation that source MAC is selected between the physical port that currently determines.Transmission node is by alternate source MAC in contingency table Physical port corresponding to location is updated to the physical port currently determined, or, it is standby in the contingency table of this transmission node to record this After the corresponding relation that source MAC is selected between the physical port that currently determines, transmission node also needs to send to host node Carry the 4th Fast-Hello reports of the MAC Address of the alternative source MAC, the physical port currently determined and this transmission node Text.
Based on the form of the Fast-Hello messages shown in above-mentioned table 1, for the 4th Fast-Hello messages, its AGG_ The value of HASH_MODE fields is designated identification (such as 2), the 3rd Fast-Hello that its source MAC receives with transmission node The source MAC carried in message is identical, i.e., corresponding alternative source MAC, and the value of its SYSTEM_MAC_ADDR field is The MAC Address of this transmission node, the value of its RCV_PORT field are the physical port (port of such as physical port currently determined Number).It is identical with the value of prior art for the value of other fields, it will not be repeated here.
As shown in figure 1, equipment B is after the 3rd Fast-Hello messages 1 are received, due to not received by aggregated links 3rd Fast-Hello messages 1, therefore equipment B obtains alternative source MAC 1, and profit from the 3rd Fast-Hello messages 1 Enter line link between multiple physical ports corresponding to aggregated links (port 3, port 4 and port 5) with alternative source MAC 1 Load balancing, it is assumed that link load sharing result is port 3, then forwards the 3rd Fast-Hello messages 1 by port 3.For The processing of other 3rd Fast-Hello messages, it is similar with the processing of the 3rd Fast-Hello messages 1, it will not be repeated here.
Equipment C is after the 3rd Fast-Hello messages 1 are received, due to receiving the 3rd Fast- by aggregated links Hello packet 1, therefore equipment C obtains alternative source MAC 1 from the 3rd Fast-Hello messages 1, and utilize alternate source MAC Address 1 enters uplink iotaoad point between multiple physical ports corresponding to aggregated links (port 9, port 10 and port 11) Load, it is assumed that link load sharing result is port 9, then equipment C forwards the 3rd Fast-Hello messages 1 by port 9.In this base On plinth, equipment C also needs to obtain alternative source MAC (the i.e. alternative source MAC carried in the 3rd Fast-Hello messages 1 1), and determine to receive the physical port (i.e. port 6) of the 3rd Fast-Hello messages 1 on equipment C.Afterwards, if equipment C pass Record has the corresponding relation between alternative source MAC 1 and port 6 in connection table, then equipment C need not update contingency table；If The corresponding relation between alternative source MAC 1 and port 6 is not recorded in equipment C contingency table, then equipment C needs associating The corresponding relation between alternative source MAC 1 and port 6 is recorded in table, and is sent to host node (device A) and carries alternate source 4th Fast-Hello messages of the MAC Address (being assumed to be MAC-C) of MAC Address 1, port 6 and equipment C, i.e. the 4th Fast- The source MAC of hello packet is alternative source MAC 1, the SYSTEM_MAC_ADDR fields of the 4th Fast-Hello messages Value be MAC-C, the value of the RCV_PORT fields of the 4th Fast-Hello messages is port 6.For other 3rd Fast- The processing of hello packet, it is similar with the processing of the 3rd Fast-Hello messages 1, it will not be repeated here.
Equipment D processing is similar with equipment C processing, will not be repeated here.Equipment E is receiving the 3rd Fast-Hello After message 1, due to receiving the 3rd Fast-Hello messages 1 by aggregated links, therefore directly the 3rd is forwarded by port 19 Fast-Hello messages 1.On this basis, equipment E also needs to obtain the alternate source carried in the 3rd Fast-Hello messages 1 MAC Address (i.e. alternative source MAC 1), and determine to receive the physical port of the 3rd Fast-Hello messages 1 on equipment E (as held Mouth is 17).Afterwards, if record has the corresponding relation between alternative source MAC 1 and port 17 in equipment E contingency table, set Standby E need not update contingency table；If pair between alternative source MAC 1 and port 17 is not recorded in equipment E contingency table It should be related to, then equipment E needs to record corresponding relation between alternative source MAC 1 and port 17 in contingency table, and to main section Point (device A) sends the 4th of the MAC Address (being assumed to be MAC-E) for carrying alternative source MAC 1, port 17 and equipment E Fast-Hello messages, the i.e. source MAC of the 4th Fast-Hello messages are alternative source MAC 1, the 4th Fast-Hello The value of the SYSTEM_MAC_ADDR fields of message is MAC-E, the value of the RCV_PORT fields of the 4th Fast-Hello messages For port 17.Processing for other 3rd Fast-Hello messages, it is similar with the processing of the 3rd Fast-Hello messages 1, This is repeated no more.
Step 4, host node receives the 4th Fast-Hello messages from transmission node, based on the 4th Fast-Hello The MAC Address of the alternative source MAC, physical port and the transmission node that are carried in message, host node is in the alternative source MAC The MAC Address of lower record physical port and transmission node.For example, host node is with receiving the carrying alternate source MAC from equipment C After 4th Fast-Hello messages of location 1, port 6 and MAC-C, in alternative 1 time record port 6 of source MAC and MAC-C.
It should be noted that the 3rd Fast-Hello messages sent for host node, if this host node passes through polymerization Link receives the 3rd Fast-Hello messages, then host node is also required to carry in the 3rd Fast-Hello messages standby Select the physical port for receiving the 3rd Fast-Hello messages under source MAC on minute book host node and this host node MAC Address；In addition, if host node does not receive the 3rd Fast-Hello messages by aggregated links, host node is direct Abandon the 3rd Fast-Hello messages.
Step 5, maintenance port is distinguished for each alternative source MAC based on the relevant information recorded in step 4, host node Chained list.Wherein, by the MAC Address for recording each node for thering are the 3rd Fast-Hello messages to pass through and each section in the chained list of port The physical port of the 3rd Fast-Hello messages is received on point.
In the embodiment of the present invention, for step 2, host node is after first the 3rd Fast-Hello message is sent, also Source MAC screening timers can be started.When host node receives the 4th Fast-Hello messages every time, refresh source MAC screening timings Device.Based on this, after source MAC screens timer expiry, then host node distinguishes maintenance port chained list for each alternative source MAC. Wherein, the time-out time of source MAC screenings timer can arbitrarily be set according to practical experience, such as be arranged to 24*Fast-Hello The transmission cycle of message.
Step 6, host node utilize each alternatively alternate source of the port chained list corresponding to source MAC from default second quantity The source MAC of default first quantity is selected in MAC Address.
Specifically, default first quantity port chained list is divided into a port chained list group, port chained list group by host node In port chained list it is incomplete same；For each port chained list group, host node determines to preset the corresponding to the port chained list group The collision probability that the alternative source MAC of one quantity is received by the same physical port on same node, and host node selection punching The alternative source MAC of the first quantity is preset corresponding to the minimum port chained list group of prominent probability, for default first number selected The source MAC of amount.
For example, it is assumed that the alternative corresponding ports chained list 1 of source MAC 1, the alternative corresponding ports chained list 2 of source MAC 2, alternatively The corresponding ports chained list 3 of source MAC 3, the alternative corresponding ports chained list 4 of source MAC 4, the alternative corresponding ports chain of source MAC 5 Table 5, the alternative corresponding ports chained list 6 of source MAC 6, the alternative corresponding ports chained list 7 of source MAC 7, alternative source MAC 8 are right Answer port chained list 8.Then：Port chained list 1, port chained list 2 and port chained list 3 are divided into port chained list group 1 by host node, by port Chained list 1, port chained list 2 and port chained list 4 are divided into port chained list group 2, by port chained list 1, port chained list 2 and port chained list 5 It is divided into port chained list group 3 ..., by that analogy, host node can divide the individual port chained list groups of C (8,3), i.e. 56 ports altogether Chained list group.
For port chained list group 1, host node determines alternative source MAC 1, alternative source MAC 2, alternative source MAC 3 collision probabilities received by the same physical port on same node.Wherein, if alternative source MAC 1, alternate source MAC 3rd Fast-Hello messages corresponding to location 2, alternative source MAC 3 are received by the port 6 on equipment C, then collision probability is 1.If the 3rd Fast-Hello messages corresponding to alternative source MAC 1, alternative source MAC 2, alternative source MAC 3 are equal Received by the port 6 on equipment C, and received by the port 12 on equipment D, then collision probability is 2, by that analogy.For end Mouth chained list group 2, host node determines alternative source MAC 1, alternative source MAC 2, alternative source MAC 4 by same node The collision probability that receives of same physical port...., by that analogy, host node can determine the conflict of 56 port chained list groups Probability.Collision probability based on 56 port chained list groups, it is assumed that the minimum port chained list group of collision probability is port chained list group 2, Then host node can be with alternative source MAC 1, alternative source MAC 2, alternative source MAC 4 corresponding to selection port chained list group 2 For three source MACs selected in step 202.
Further, in order to determine corresponding to the chained list group of port preset the first quantity alternative source MAC by same section The collision probability that same physical port on point receives, in a kind of specific implementation of the embodiment of the present invention, including but not It is limited by following steps and determines corresponding collision probability：
Step 61, the MAC recorded in each port chained list is counted for all of the port chained list in the chained list group of port, host node Address and physical port.Such as port chained list 1, port chained list 2 and the port chained list 3 in port chained list group 1, host node statistics The MAC Address and physical port recorded in each port chained list.
Assuming that the port chained list 1 that host node, which is alternative source MAC 1, to be safeguarded is as shown in table 2, tieed up for alternative source MAC 2 The port chained list 2 of shield is as shown in table 3, and the port chained list 3 for alternative source MAC 3-dimensional shield is as shown in table 4, for alternate source MAC The port chained list 4 that location 4 is safeguarded is as shown in table 5, and the port chained list 5 safeguarded for alternative source MAC 5 is as shown in table 6, is alternate source The port chained list 6 that MAC Address 6 is safeguarded is as shown in table 7, and the port chained list 7 safeguarded for alternative source MAC 7 is as shown in table 8, is The port chained list 8 that alternative source MAC 8 is safeguarded is as shown in table 9.Based on each port chained list, host node can count each port The MAC Address and physical port recorded in chained list.

Table 9
Alternative source MAC 8 MAC-C, port 7；MAC-D, port 13；MAC-E, port 18
Step 62, if alternative source MAC is corresponding in respective port chained list corresponding to each port chained list difference MAC Address and physical port are identicals, then host node needs to add 1 to the collision probability of port chained list group.Wherein, each port chain The initial value of the collision probability of table group can be 0.
For port chained list group 1, the MAC that is recorded in host node statistics port chained list 1, port chained list 2 and port chained list 3 Location and physical port.Based on this, alternative corresponding ports 6 on MAC-C of source MAC 1, alternative source MAC 2 is on MAC-C Corresponding ports 7, alternative corresponding ports 8 on MAC-C of source MAC 3, therefore each alternative physics of the source MAC on MAC-C Port is different, therefore does not add 1 to the collision probability of port chained list group 1；Alternative corresponding ports 12 on MAC-D of source MAC 1, Alternative corresponding ports 13 on MAC-D of source MAC 2, alternative corresponding ports 14 on MAC-D of source MAC 3, therefore it is each standby Select physical port of the source MAC on MAC-D different, therefore 1 is not added to the collision probability of port chained list group 1；Alternate source MAC Corresponding ports 17 on MAC-E of address 1, alternative corresponding ports 18 on MAC-E of source MAC 2, alternative source MAC 3 exist The upper corresponding ports 17 of MAC-E, therefore physical port of each alternative source MAC on MAC-E is different, therefore not to port chained list The collision probability of group 1 adds 1.
Step 63, host node calculates the collision probability of each port chained list group.Wherein, carried out to each port chained list group After the processing of step 62, host node can calculate the collision probability of each port chained list group.
In the embodiment of the present invention, if the port chained list group of collision probability minimum is 1, step 64 is performed；If punching The minimum port chained list group of prominent probability is multiple, then performs step 65.
Step 64, host node determines that the port chained list group (i.e. the minimum port chained list group of collision probability) is by same node On the minimum port chained list group of the collision probability that receives of same physical port.
For example, if the collision probability that host node calculates exit port chained list group 1 is minimum, it is determined that the port chained list group 1 is The port chained list group of the collision probability minimum received by the same physical port on same node.
Step 65, for all of the port in multiple port chained list groups (i.e. the minimum multiple port chained list groups of collision probability) Chained list, host node count the MAC Address and physical port recorded in each port chained list.
For example, it is minimum that if host node, which calculates exit port chained list group 1 and the collision probability of port chained list group 2, lead Node needs to count port chained list 1 in port chained list group 1, the MAC Address and thing that are recorded in port chained list 2 and port chained list 3 Port is managed, and counts the MAC Address and thing recorded in the port chained list 1 in port chained list group 2, port chained list 2 and port chained list 4 Manage port.
Step 66, for any two port chained list in all of the port chained list, if two port chained lists are right respectively The alternative source MAC answered corresponding MAC Address and physical port in two port chained lists are identicals, then host node needs 1 is added to the collision probability of port chained list group.
For port chained list group 1, for port chained list 1 and port chained list 2, alternative source MAC 1 is corresponding on MAC-C Port 6, alternative corresponding ports 7 on MAC-C of source MAC 2, therefore each alternative physical port of the source MAC on MAC-C Difference, 1 is not added to the collision probability of port chained list group 1；Alternative corresponding ports 12 on MAC-D of source MAC 1, alternate source MAC Corresponding ports 13 on MAC-D of address 2, therefore physical port of each alternative source MAC on MAC-D is different, not to port The collision probability of chained list group 1 adds 1；Alternative corresponding ports 17 on MAC-E of source MAC 1, alternative source MAC 2 is in MAC-E Upper corresponding ports 18, therefore physical port of each alternative source MAC on MAC-E is different, not to the conflict of port chained list group 1 Probability adds 1.For port chained list 1 and port chained list 3, alternative corresponding ports 6 on MAC-C of source MAC 1, alternate source MAC Corresponding ports 8 on MAC-C of location 3, therefore physical port of each alternative source MAC on MAC-C is different, not to port chained list The collision probability of group 1 adds 1；Alternative corresponding ports 12 on MAC-D of source MAC 1, alternative source MAC 3 are right on MAC-D Port 14 is answered, therefore physical port of each alternative source MAC on MAC-D is different, not to the collision probability of port chained list group 1 Add 1；Alternative corresponding ports 17 on MAC-E of source MAC 1, alternative corresponding ports 17 on MAC-E of source MAC 3, therefore Each alternative physical port of the source MAC on MAC-E is identical, it is necessary to add 1 to the collision probability of port chained list group 1.For end Mouth chained list 2 and port chained list 3, alternative corresponding ports 7 on MAC-C of source MAC 2, alternative source MAC 3 are right on MAC-C Port 8 is answered, therefore physical port of each alternative source MAC on MAC-C is different, not to the collision probability of port chained list group 1 Add 1；Alternative corresponding ports 13 on MAC-D of source MAC 2, alternative corresponding ports 14 on MAC-D of source MAC 3, therefore Physical port of each alternative source MAC on MAC-D is different, does not add 1 to the collision probability of port chained list group 1；Alternate source MAC Corresponding ports 18 on MAC-E of address 2, alternative corresponding ports 17 on MAC-E of source MAC 3, therefore each alternate source MAC Physical port of the location on MAC-E is different, does not add 1 to the collision probability of port chained list group 1.Based on above-mentioned processing, port chained list The collision probability of group 1 is 1.
Step 67, host node calculate multiple port chained list groups (the collision probability minimum calculated in step 63 it is multiple Port chained list group) in each port chained list group collision probability.Wherein, to the minimum multiple port chained list groups of collision probability In each port chained list group carry out step 66 processing after, host node can calculate the collision probability of each port chained list group. If the minimum port chained list group of collision probability is 1, step 68 is performed；If the minimum port chained list group of collision probability is It is multiple, then perform step 69.
Step 68, host node determines port chained list group (the port chained list of the collision probability minimum determined in step 67 Group) it is the minimum port chained list group of the collision probability received by the same physical port on same node.For example, step 67 is fallen into a trap The collision probability for calculating port chained list group 1 is minimum, it is determined that the port chained list group 1 is by the same physical port on same node The port chained list group of the collision probability minimum received.
Step 69, port chained list group (the multiple conflicts that in step 67 determine of the host node from multiple collision probabilities minimum The minimum port chained list group of probability) in any selection a port chained list group (such as：Selection port chained list group mark is minimum or maximum Port chained list group), and determine the port chained list group of the selection for the conflict that is received by the same physical port on same node The minimum port chained list group of probability.
In the embodiment of the present invention, when the aggregated links of transmission node changes, transmission node sends the to host node Four Fast-Hello messages, host node after the 4th Fast-Hello messages are received, if current chosen complete default first The source MAC of quantity, then host node needs to reselect the source MAC of default first quantity, and utilizes what is reselected Source MAC performs subsequent step.And/or when the aggregated links of host node changes, if current chosen complete pre- If the source MAC of the first quantity, then host node needs to reselect the source MAC of default first quantity, and using again The source MAC of selection performs subsequent step.And/or after host node detects that link breaks down, if currently selected The source MAC of default first quantity is selected, then host node needs to reselect the source MAC of default first quantity, and profit Subsequent step is performed with the source MAC reselected.
In the embodiment of the present invention, the information recorded in the contingency table of transmission node is removed if desired, then host node is being sent out When sending Fast-Hello messages, the RCV_PORT fields of Fast-Hello messages can also be arranged to 0xFFFF.Based on this, respectively Transmission node is after Fast-Hello messages are received, if it find that the value of RCV_PORT fields is 0xFFFF, then empties this The information recorded in ground contingency table.
In summary, host node and each transmission node can carry out link load sharing using source MAC, so that Three continuous Fast-hello messages are forwarded on the different links of aggregated links, reduce the probability of RRPP error detections, And the problems such as can avoiding causing detection concussion and temporary loop.
