Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of Proxy Method and equipment of aggregation port.
Background technology
As shown in Figure 1, for example, chip 1 on the network equipment (switch) A passes through three physical link polymerizations of aggregation group 1 with the chip 2 on network equipment B, the member of the aggregation group 1 of network equipment A comprises port one, port 2 and port 3, and the member of the aggregation group 1 of network equipment B comprises port 7, port 8 and port 9.Chip 3 on network equipment A passes through three physical link polymerizations of aggregation group 2 with the chip 4 on network equipment C, the member of the aggregation group 2 of network equipment A comprises port 4, port 5 and port 6, and the member of the aggregation group 2 of network equipment C comprises port one 0, port one 1 and port one 2.Further, maintenance port state table on each network equipment, this Port State Table is for recording the corresponding relation between port and port status.When port status is Forwarding (forwarding) state, port can be received and dispatched flow; When port status is Standby (preparation) state, port can receive flow, but cannot transmitted traffic; When port status is Down (fault) state, port cannot be received and dispatched flow.
For the traffic transport process of network equipment A and network equipment B, suppose that port one, port 2 and port 3 are all in Forwarding state, the aggregation group of aggregation group 1 correspondence of chip 1 is transmitted and is comprised port one, port 2 and port 3.Chip 1 is when receiving that object is the flow of aggregation group 1, flow is carried out to hash, and the aggregation group based on this aggregation group 1 correspondence of hash result queries transmits, the port (port one or port 2 or port 3) of transmitting middle correspondence in aggregation group by hash result sends to chip 2 by flow.
When the port status of the port 3 of network equipment A need to switch to Standby state by (Forwarding) state of forwarding, network equipment A sends handoff notification message to network equipment B, by network equipment B, the port status of port 9 is switched to Standby state, and to network equipment A, return and complete the notification message that Standby state switches after switching completes, like this, network equipment A is after receiving this notification message, port status by port 3 in Port State Table switches to Standby state by Forwarding state, afterwards, network equipment A can first upgrade the member of aggregation group 1 by all ports in Forwarding state in Port State Table, the member who is aggregation group 1 is port one and port 2, port 3 is no longer the member of aggregation group 1, but separate port, the flow of port blocked 3 again, not from port 3 transmitted traffics, also flow that can first port blocked 3, then upgrade the member of aggregation group 1.Subsequent network device A, after completing the switching of Standby state, switches to fault (Down) state by the port status of port 3 by Standby state.
It should be noted that, the processing procedure that above-mentioned network equipment B switches to the port status of port 9 Standby state is identical with the processing procedure that network equipment A switches to Standby state by the port status of port 3, does not repeat them here.
In above-mentioned processing procedure, network equipment A is when switching to Standby state by the port status of port 3, if first upgrade the member of aggregation group 1, the flow of port blocked 3 again, owing to blocking flow, need the regular hour, during this period of time, port 3 is separate port (not being the members of aggregation group 1), the member of aggregation group 1 only has port one and port 2, the object of receiving for chip 1 is the broadcast traffic of aggregation group 1, except flow being sent to chip 2 by port one or port 2, also can copy portion and send to chip 2 by port 3, occur that many parts of identical flows are to chip 2.Further, suppose that chip 1 receives the broadcast traffic from chip 2 from port one, also can flow be sent to chip 2 from port 3, there is loop in flow.
If the flow of first port blocked 3, upgrade again the member of aggregation group 1, so, before completing renewal operation, the member of aggregation group 1 is still port one, port 2 and port 3, for chip 1, receives that object is the flow of aggregation group 1, if needed after hash, by port 3, send, but port 3 has got clogged, cannot transmitted traffic, this just causes traffic loss.
Network equipment A switches to the port status of port 3 after Down state, if the port status of port 3 need to be switched to Forwarding state by Down state, the port status of port 3 is being switched to Standby state phase by Down state, the port 3 blocking before not opening, the port status of port 3 is being switched to Forwarding state phase by Standby state, just open the port 3 blocking before, so still have the situation of traffic loss.

Embodiment
For problems of the prior art, the embodiment of the present invention provides a kind of Proxy Method of aggregation port, be applied in the application scenarios that carries out link aggregation by many physical links, between first network equipment and second network equipment, by many physical links, carry out link aggregation.The application scenarios schematic diagram that the Fig. 1 of take is the embodiment of the present invention, when the chip 1 of network equipment A passes through three physical link polymerizations of aggregation group 1 with the chip of network equipment B 2, first network equipment is network equipment A, second network equipment is network equipment B.When the chip 3 of network equipment A passes through three physical link polymerizations of aggregation group 2 with the chip of network equipment C 4, first network equipment is network equipment A, and second network equipment is network equipment C.
Under above-mentioned application scenarios, as shown in Figure 2, the Proxy Method of this aggregation port comprises the following steps:
Step 201, first network equipment is when receiving the notification message of the Standby state that the completes switching that second network equipment sends, and the aggregation port that the aggregation port with having completed the switching of Standby state on second network equipment is connected is defined as first by proxy port.
In the embodiment of the present invention, the port status that has completed the aggregation port of Standby state switching on second network equipment is while switching to Standby state by Forwarding state, this notification message is that second network equipment is after receiving the handoff notification message sending when first network equipment need to be switched to Standby state by the port status of proxy port by Forwarding state by first, the aggregation port being connected by proxy port with first is defined as to second by proxy port, arbitrary other aggregation port in being transmitted by aggregation group corresponding to the aggregation group at proxy port place second is defined as second agent's port, and second during corresponding aggregation group is transmitted is updated to and sends after second agent's port by proxy port.
Further, the port status that has completed the aggregation port of Standby state switching on second network equipment is while switching to Standby state by forwarding Forwarding state, first network equipment in aggregation group is transmitted first by proxy port, be updated to first agent's port after, block first by proxy port.In this case, notification message in above-mentioned steps 201 is that second network equipment is after receiving the handoff notification message sending when first network equipment need to be switched to Standby state by the port status of proxy port by Forwarding state by first, the aggregation port being connected by proxy port with first is defined as to second by proxy port, arbitrary other aggregation port in being transmitted by aggregation group corresponding to the aggregation group at proxy port place second is defined as second agent's port, and second during corresponding aggregation group is transmitted is updated to second agent's port by proxy port, and obstruction second is sent after proxy port.
Further, the port status that has completed the aggregation port of Standby state switching on second network equipment is while switching to Standby state by Down state, first network equipment in aggregation group is transmitted first by proxy port, be updated to first agent's port after, open first by proxy port.
In this case, notification message in above-mentioned steps 201 is that second network equipment is after receiving the handoff notification message sending when first network equipment need to be switched to Standby state by the port status of proxy port by Down state by first, the aggregation port being connected by proxy port with first is defined as to second by proxy port, arbitrary other aggregation port in being transmitted by aggregation group corresponding to the aggregation group at proxy port place second is defined as second agent's port, and second during corresponding aggregation group is transmitted is updated to second agent's port by proxy port, and opening second is sent after proxy port.
Step 202, first network equipment arbitrary other aggregation port in being transmitted by aggregation group corresponding to the aggregation group at proxy port place first is defined as first agent's port.
As shown in Figure 1, suppose that first is port 3 by proxy port, first network equipment is from the aggregation group of aggregation group 1 correspondence at port 3 places is transmitted, and selecting other port (as port one or port 2) outside port 3 is first agent's port.
In the embodiment of the present invention, first network equipment arbitrary other aggregation port in being transmitted by aggregation group corresponding to the aggregation group at proxy port place first is defined as first agent's port, specifically comprise: first network equipment according to first by the BasePtr of the aggregation group at proxy port place (base pointer) and aggregation group number of members, inquire about local aggregation group and transmit, obtain first and transmitted by aggregation group corresponding to the aggregation group at proxy port place; In all of the port of first network equipment from corresponding aggregation group is transmitted, select arbitrary except first by other aggregation port proxy port as first agent's port.
Wherein, BasePtr points to aggregation group first port in aggregation group is transmitted, and aggregation group number of members represents from the port of BasePtr sensing, the port number that aggregation group is corresponding.
Concrete, first network equipment disposes aggregation group table, BasePtr corresponding to aggregation group and aggregation group and aggregation group number of members in this aggregation group table, have been recorded, and the BasePtr of aggregation group points to aggregation group and in aggregation group, transmits first port of middle correspondence, the port that the aggregation group number of members of aggregation group represents to point to from BasePtr, the port number that aggregation group is corresponding.Based on aggregation group table, first network equipment can inquire first by aggregation group corresponding to proxy port in aggregation group table, and determines BasePtr and the aggregation group number of members of this aggregation group.First network equipment is according to BasePtr and aggregation group number of members, in aggregation group is transmitted, find first by all of the port in aggregation group corresponding to proxy port, and from all of the port, select first by other port outside proxy port as first agent's port.
Under the application scenarios shown in Fig. 1, the member of the aggregation group 1 of network equipment A comprises port one, port 2 and port 3, and the member of aggregation group 2 comprises port 4, port 5 and port 6.Based on this, a kind of example of aggregation group table can be as shown in table 1, and a kind of example that aggregation group is transmitted can be as shown in table 2.Suppose that first is port 3 by proxy port, the aggregation group table based on shown in table 1 and the aggregation group shown in table 2 are transmitted, and whether the member of network equipment A inquiry aggregation group 1 comprises port 3, if comprised, determine that the aggregation group of port 3 correspondences is aggregation group 1; If do not comprised, whether the member of network equipment A inquiry aggregation group 2 comprises port 3, by that analogy.When whether the member of network equipment A inquiry aggregation group 1 comprises port 3, network equipment A is from first port (port one) of the BasePtr sensing of aggregation group 1, judge 3 ports that aggregation group starts from port one in transmitting and whether comprise port 3, because port 3 is the 3rd ports that start from port one during aggregation group is transmitted, therefore the member of aggregation group 1 comprises port 3, and the aggregation group of port 3 correspondences is aggregation group 1.Afterwards, network equipment A determines that first port that the BasePtr of aggregation group 1 points to is the port one during aggregation group is transmitted, and the aggregation group number of members of definite aggregation group 1 is 3, therefore, network equipment A is according to BasePtr and aggregation group number of members, in aggregation group is transmitted from first port start to search successively first by other port outside proxy port (port 3) as first agent's port, due to first port-for-port 1, this port one is first by other port outside proxy port, therefore search procedure finishes, network equipment A directly selects port one as first agent's port.

Certainly, in actual applications, be not limited to the mode of above-mentioned definite first agent's port, for example, the aggregation group table on first network equipment shown in allocation list 3, has recorded the corresponding relation between all of the port in aggregation group and aggregation group in this aggregation group table.Based on this aggregation group table, first network equipment can directly inquire first by aggregation group corresponding to proxy port in aggregation group table, and from the corresponding all of the port of aggregation group inquiring, select first by other port outside proxy port as first agent's port.The mode of determining first agent's port for other, repeats no more in the embodiment of the present invention.
Table 3
| Aggregation group | All of the port in aggregation group |
| Aggregation group 1 | Port one, port 2 and port 3 |
| Aggregation group 2 | Port 4, port 5 and port 6 |
Step 203, first network equipment first during aggregation group is transmitted is updated to first agent's port by proxy port, and when receiving that object is the flow of aggregation group, according to the aggregation group after renewal corresponding to this aggregation group, transmits flow is forwarded.
As shown in Figure 1, suppose that first is port 3 by proxy port, network equipment A selects port one as first agent's port.Based on this, for the aggregation group 1 of port 3 correspondences, in this aggregation group 1, still safeguard that first by proxy port, the member of aggregation group 1 still comprises port one, port 2 and port 3.Aggregation group for aggregation group 1 correspondence is transmitted, and will use first agent's port to upgrade first by proxy port, and the aggregation group of aggregation group 1 correspondence is transmitted port one, port 2 and the port 3 of middle record, will be updated to port one, port 2 and port one.
In the embodiment of the present invention, when the aggregation group 1 of flow by the first chip sends to the second chip, the first chip will be transmitted the port repeat flow of middle record by the aggregation group of aggregation group 1 correspondence.When the aggregation group of aggregation group 1 correspondence is transmitted the port-for-port 1, port 2 of middle record and port 3, flow carries out flow load sharing between port one, port 2 and the port 3 of the first chip, as carried out flow load sharing by hash algorithm, and the first chip based on flow load sharing result (port one, port 2 or port 3) to the second chip transmitted traffic.When the aggregation group of aggregation group 1 correspondence is transmitted the port-for-port 1, port 2 of middle record and port one, flow carries out flow load sharing between port one, port 2 and the port one of the first chip, as carried out flow load sharing by hash algorithm, and the first chip based on flow load sharing result (port one, port 2 or port one) to the second chip transmitted traffic.
In the embodiment of the present invention, second network equipment is determined the mode of second agent's port, determines that the mode of first agent's port is similar with first network equipment, does not repeat them here.Second network equipment is updated to the process of transmitted traffic after second agent's port by second by proxy port, and by first, by proxy port, to be updated to after first agent's port the process of transmitted traffic similar with first network equipment, do not repeat them here.
Below in conjunction with following two kinds of situations, the agent process of aggregation port is further detailed.
Situation one, the port status of aggregation port is switched to Down state by Forwarding state.
In the time the port status of port 3 (being aggregation port) need to being switched to Down state by Forwarding state, network equipment A sends and the port status of port 3 need to be switched to the handoff notification message of Standby state by Forwarding state to network equipment B.
Network equipment B is when receiving this handoff notification message, the aggregation port being connected with port 3 (being port 9) is defined as to second by proxy port, arbitrary other aggregation port during the aggregation group corresponding to aggregation group at port 9 places transmitted is (as port 7 or port 8, suppose to select port 7) be defined as second agent's port, the port 9 during corresponding aggregation group is transmitted is updated to port 7.Concrete, network equipment B is when receiving handoff notification message, port status by port 9 in Port State Table is revised as Standby state, and at the interior maintenance port 7 of aggregation group 1, port 8 and port 9 (i.e. all port and ports in Forwarding state in Standby state in the interior maintenance port state table of aggregation group 1), by the port 7 of aggregation group 1 interior maintenance, port 8 and port 9 are updated to the aggregation group of aggregation group 1 correspondence and transmit, and the port of aggregation group being transmitted to middle record is by port 7, port 8 and port 9 are updated to port 7, port 8 and port 7.
Network equipment B sends and has completed the notification message that Standby state switches (being that network equipment B has switched to port status Standby state) to network equipment A.
Network equipment A is when receiving this notification message, the aggregation port (port 3) that aggregation port (port 9) with having completed the switching of Standby state on network equipment B is connected is defined as first by proxy port, arbitrary other aggregation port during the aggregation group corresponding to aggregation group at port 3 places transmitted is (as port one or port 2, suppose to select port one) be defined as first agent's port, the port 3 during corresponding aggregation group is transmitted is updated to port one.Concrete, network equipment A is when receiving notification message, port status by port 3 in Port State Table is revised as Standby state, and at the interior maintenance port 1 of aggregation group 1, port 2 and port 3 (i.e. all port and ports in Forwarding state in Standby state in the interior maintenance port state table of aggregation group 1), by the port one of aggregation group 1 interior maintenance, port 2 and port 3 are updated to the aggregation group of aggregation group 1 correspondence and transmit, and the port that aggregation group is transmitted to middle record is by port one, port 2 and port 3 are updated to port one, port 2 and port one.
In specific implementation, network equipment B is when switching to Standby state by the port status of port 9 by Forwarding state, and network equipment B can port blocked 9, also port blocked 9 not.When port blocked 9, network equipment B is not from port 9 transmitted traffics.Wherein, network equipment B is when port blocked 9, and port blocked 9 is carried out after need to the aggregation group of aggregation group 1 correspondence being transmitted at network equipment B and being updated to port 7, port 8 and port 7 by port 7, port 8 and port 9.Network equipment A is when switching to Standby state by the port status of port 3 by Forwarding state, and network equipment A can port blocked 3, also port blocked 3 not, and when port blocked 3, network equipment A is not from port 3 transmitted traffics.Wherein, network equipment A is when port blocked 3, and port blocked is carried out after need to the aggregation group of aggregation group 1 correspondence being transmitted at network equipment A and being updated to port one, port 2 and port one by port one, port 2 and port 3.
Network equipment A, the port status of port 3 is switched to after Standby state, further switches to Down state by the port status of port 3 by Standby state.Network equipment B, the port status of port 9 is switched to after Standby state, further switches to Down state by the port status of port 9 by Standby state.The above-mentioned process that port status is switched to Down state by Standby state similarly to the prior art, does not repeat them here.
In above-mentioned processing procedure, when the port status of port 3 is switched to Standby state, if first the aggregation group of aggregation group 1 correspondence is transmitted and is updated to port one, port 2 and port one, through after a while, (be assumed to be 5 seconds) and just can complete the process of the flow of port blocked 3.During this period of time, the member of aggregation group 1 comprises port one, port 2 and port 3, and the aggregation group of aggregation group 1 correspondence is transmitted as port one, port 2 and port one.The broadcast traffic of receiving for chip 1, because port 3 is not separate port, therefore the first chip can not send to the second chip by flow from port 3.By flow is carried out to hash, and the aggregation group based on hash result queries aggregation group 1 correspondence transmits, and by hash result (port one or port 2), flow sent to the second chip.Therefore, the first chip only can send a flow to the second chip, there will not be the situation that sends many parts of flows.Suppose that the first chip receives the broadcast traffic from the second chip from port one, due to port 3, are members of aggregation group 1, port 3 is not separate port, therefore, the first chip can not send to the second chip by flow from port 3, and flow there will not be loop.
Situation two, the port status of aggregation port is switched to Forwarding state by Down state.
In the time the port status of port 3 (being aggregation port) need to being switched to Forwarding state by Down state, network equipment A sends and the port status of port 3 need to be switched to the handoff notification message of Standby state by Down state to network equipment B.
Network equipment B is when receiving this handoff notification message, the aggregation port being connected with port 3 (being port 9) is defined as to second by proxy port, arbitrary other aggregation port during the aggregation group corresponding to aggregation group at port 9 places transmitted is (as port 7 or port 8, suppose to select port 7) be defined as second agent's port, port 9 during corresponding aggregation group is transmitted is updated to port 7, opens port 9.Concrete, network equipment B is when receiving handoff notification message, port status by port 9 in Port State Table is revised as Standby state, and at the interior maintenance port 7 of aggregation group 1, port 8 and port 9 (i.e. all port and ports in Forwarding state in Standby state in the interior maintenance port state table of aggregation group 1), by the port 7 of aggregation group 1 interior maintenance, port 8 and port 9 are updated to the aggregation group of aggregation group 1 correspondence and transmit, and the port of aggregation group being transmitted to middle record is by port 7, port 8 and port 9 are updated to port 7, port 8 and port 7.
Network equipment B sends and has completed the notification message that Standby state switches (being that network equipment B has switched to port status Standby state) to network equipment A.
Network equipment A is when receiving this notification message, the aggregation port (port 3) that aggregation port (port 9) with having completed the switching of Standby state on network equipment B is connected is defined as first by proxy port, arbitrary other aggregation port during the aggregation group corresponding to aggregation group at port 3 places transmitted is (as port one or port 2, suppose to select port one) be defined as first agent's port, port 3 during corresponding aggregation group is transmitted is updated to port one, opens port 3.Concrete, network equipment A is when receiving notification message, port status by port 3 in Port State Table is revised as Standby state, and at the interior maintenance port 1 of aggregation group 1, port 2 and port 3 (i.e. all port and ports in Forwarding state in Standby state in the interior maintenance port state table of aggregation group 1), by the port one of aggregation group 1 interior maintenance, port 2 and port 3 are updated to the aggregation group of aggregation group 1 correspondence and transmit, and the port that aggregation group is transmitted to middle record is by port one, port 2 and port 3 are updated to port one, port 2 and port one.
