Description
Technical field
The present invention relates to the link aggregation technical field, be specifically related to the polymerization sublink and recover processing method, system and equipment.
Background technology
In Ethernet exchange field, the link aggregation technology has a very wide range of applications.Link aggregation refers to many physical links is bound into a logical links (being also referred to as aggregation group) to create the more interface of high bandwidth.The data traffic that is forwarded to aggregation group can go up load balancing at each member's physical link (being also referred to as sublink), can obtain being equivalent to the effective bandwidth of each sublink bandwidth sum like this.
Except high bandwidth can be provided, the link aggregation technology also has an important function, just provides the high reliability of network.Play a part mutual backup between each sublink in the aggregation group, certain sublink breaks down after (down), and load balancing is to other sublink again for flow, and the flow of whole aggregation group is transmitted and can't be interrupted; After this sublink is recovered normally (up) again, can participate in the load balancing of aggregation group flow again.
Fig. 1-1-Fig. 1-4 has provided the processing scheme of the polymerization sublink recovery process of prior art one.
As Figure 1-1, four port P1～P4 of device A form aggregation group, and four port P5～P8 of equipment B form aggregation group.When initial, the link between P1 and the P5 is in fault (down) state, and other three links are in normally (up) state and are forwarding (forwarding) state.Like this, aggregation group reality only comprises three ports of P2～P4 on the exchange chip of device A, and aggregation group reality only comprises three ports of P6～P8 on the exchange chip of equipment B.Upstream data fails to be convened for lack of a quorum load balancing to three ports of P6～P8; Similarly, downlink data fails to be convened for lack of a quorum load balancing to three ports of P2～P4.
Sometime, connect the link-recovery between P1 and the P5, promptly be in the up state, then P1 on device A, B and P5 can add aggregation group separately, and flow is carried out load balancing.
Here be that example is come the processing procedure of a port from down to up of devices illustrated to aggregation group with the device A, specifically comprise the steps 01～03:
01: shown in Fig. 1-2, when port P1 became up by down, the state of P1 was earlier for abandoning (discarding).This be because: for preventing the generation of double-layer loop, when port became up by down, initial condition was necessary for discarding.
02: as Figure 1-3, device A finds that the state of P1 is up, then P1 is added the aggregation group on the exchange chip, actual four ports of P1～P4 that comprise of the aggregation group on the exchange chip like this, and downlink traffic carries out load balancing by four ports of P1～P4.But,, can be abandoned by exchange chip so be forwarded to the flow of this port because P1 state at this moment is discarding.
03: after P1 added aggregation group, device A was arranged to forwarding with the state of P1, and P1 begins normal converting flow.
Through after the above-mentioned steps 01～03, device A is finished the recovery processing procedure of port P1.Equipment B is identical with device A to the recovery processing procedure of port P5.When device A and B finish when recovering to handle, link P1-P5 enters into normal data forward state.The system mode of this moment is shown in Fig. 1-4.
From said process as can be seen, in the polymerization sublink recovery process, the uplink and downlink flow certainly exists the packet loss problem, and main cause has two:
The first, step 02 is finished and step 03 also imperfect tense can packet loss.Because P1 added aggregation group and flow was carried out load balancing this moment, and the state of P1 still is discarding at this moment, can be abandoned by chip so be forwarded to the flow of P1, as Figure 1-3.
The second, device A and B always have successively in time to the processing of link-recovery, handle when an end and finish, but when the other end is not also finished dealing with, just may be dropped after the flow that sends from an equipment arrives another equipment.The system mode of this moment is shown in Fig. 1-5: P1 can be abandoned by P5 to the downlink traffic that P5 sends.
Application number provides another kind of polymerization sublink to recover processing scheme for 200810211996.5 patent application, and is specific as follows:
Have aggregated links between device A and the equipment B, wherein the port of a polymerization sublink on device A is a, and the port on equipment B is b, this polymerization sublink down, and sometime, port a becomes up, then:
When device A found that the state of port a is up, then device A sent a port status renewal message by port a to the port b of equipment B.And this moment, the port b of equipment B may be in the up state and known by equipment B, also may be in other state, then:
One, if port b has been in the up state and has been known by equipment B, then port b can receive the port status renewal message that device A is sent, thereby confirms that port a has been in the up state, and then equipment B is replied response message by port b to port a.After port a receives described response message, confirm that port b also is in the up state.
Through said process, port a, b can confirm that the other side's port all is in the up state, then device A, B report the port status change information to console module simultaneously, and console module carries out computing according to this port status change information, and upgrading port a, b is the Selected state.
Two, if port b is not in the state of described " be in the up state and known by equipment B ", then equipment B can't receive that the port status that equipment a sends upgrades message, therefore can not send response message to device A yet, at this moment, port a enters wait state, and the port status that waiting facilities B initiatively sends upgrades message.
After this, when the port b of equipment B enters the up state and has been known by equipment B, equipment B is initiatively passed through port b and is upgraded message to port a transmit port state, because port a this moment has been in the up state and has been known by device A, then port a can receive that the port status that port b sends upgrades message, and replys response message to port b.
Through said process, port a, b can confirm that the other side's port all is in the up state, then device A, B report the port status change information to console module simultaneously, and console module carries out computing according to this port status change information, and upgrading port a, b is the Selected state.
The shortcoming of above-mentioned application is: since the state of a ports having for " Selected " after, the flow that is forwarded on this port just can not lost, and console module is when being provided with the Selected state of port a, b, be provided with and have priority on the time, so just may produce the packet loss phenomenon.For example: if port a is set to the Selected state earlier, and be set to the Selected state behind the port b, then the flow that is forwarded on the port b of port a just might be lost.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 2 recovers process chart for the polymerization sublink that the embodiment of the invention provides, as shown in Figure 2, in the present embodiment, has aggregated links between set device A and the B, wherein the port of a polymerization sublink on device A, B is respectively port a, b, and its concrete steps are as follows:
Step 201: be in the port of up state for each, be defined as follows state respectively at sending direction and receive direction:
Sending direction: send (Tx discarding) state that abandons, send (Tx forwarding) state of forwarding;
Receive direction: receive (Rx discarding) state that abandons, receive (Rx forwarding) state of forwarding.
Wherein, Tx discarding represents that the sending direction of port is in the discarding state, though that is: port is in the up state, this moment, this port also was not allowed to outside converting flow;
Tx forwarding represents that the sending direction of port is in the forwarding state, that is: port is in the up state, and is allowed to outside converting flow;
Rx discarding represents that the receive direction of port is in the discarding state, though that is: port is in the up state, is not allowed to receive flow, and the flow that promptly is transmitted to this port this moment can be dropped;
Rx forwarding represents that the receive direction of port is in the forwarding state, that is: port is in the up state, and is allowed to receive flow, and the flow that promptly is transmitted to this port can not be dropped.
Be in the port of up state for each, at sending direction and respectively corresponding state of receive direction of this port.For sending direction, this state is Tx discarding or Tx forwarding; For receive direction, this state is Rx discarding or Rx forwarding.
Step 202: preestablish the flow that the polymerization sublink port that is in Tx discarding state is not shared aggregation group.
Step 203: device A finds that the state of a port a of polymerization sublink becomes up by down, and then the state of the sending direction of the port a state that is set to Tx discarding, receive direction is set to Rx discarding, and port a is added aggregation group.
As long as the port up of the polymerization sublink of this equipment of device discovery, the state that the state of the sending direction of this port will be set to Tx discarding, receive direction earlier is set to Rxdiscarding earlier.
In this step, though port a has added aggregation group, because the state of its sending direction is Tx discarding, therefore, port a does not share the flow of aggregation group.
Step 204: device A finds that port a has been ready to converting flow, the state of the sending direction of port a need have been become Tx forwarding, then to the port b of equipment B transmit port status poll message.
Step 205: the port b of equipment B receives the port status query message, judges whether the state of the receive direction of port b is Rx forwarding, if, execution in step 207; Otherwise, execution in step 206.
For a polymerization sublink port, behind this port up, if this port place this port of device discovery has performed the preparation that receives flow, then equipment can become Rx forwarding by Rx discarding with the state of the receive direction of this port.
Step 206: equipment B continues wait, when the receive direction of port b is in Rx forwarding state, and execution in step 207.
Step 207: equipment B is returned response message by port b to port a, and device A is received response message, and the state of the sending direction of port a is changed to Tx forwarding, and beginning is to port b converting flow.
When the state of port became Tx forwarding, this port began to share the flow of aggregation group.
In the reality, in order not allow the device A response message of waiting facilities B indefinitely, can do following processing: default first-class is treated duration, if wait for that default device A is not received the response message that equipment B is sent in the duration, then device A repeats to equipment B transmit port status poll message, if repeat not receive the response message that equipment B is sent yet behind the preset times transmit port status poll message, then device A changes to Tx forwarding with the state of port a automatically.
Need to prove, when device A is passed through port a to the port b of equipment B transmit port status poll message, the port b of equipment B may also not be in the up state yet, at this moment, this message can not arrive equipment B, and then device A is found not receive the response message that equipment B is sent default the wait in the duration, can repeat to equipment B transmit port status poll message, if pre-determined number is not received the response message that device A is sent continuously, then device A changes to Tx forwarding with the state of port a automatically.
By said process as can be seen: for the port at polymerization sublink two ends, when the state of polymerization sublink port was Tx discarding, this port was not shared the flow of aggregation group; After having only the receive direction of having confirmed Peer-Port to be in Rx forwarding state, the state of the sending direction of local terminal port just can be set to Tx forwarding, that is: only after having confirmed that Peer-Port has performed the preparation that receives flow, the local terminal port just begins to share the flow of aggregation group, like this, the other side's port has begun the phenomenon of transmitted traffic with regard to having avoided side's polymerization sublink port also not perform the preparation that receives flow, has eliminated the generation of packet loss phenomenon fully.
When equipment B found that the state of the port b of polymerization sublink becomes up by down, the processing procedure immediate reasoning when its processing procedure can find that the state of the port a of polymerization sublink becomes up by down by the said equipment A obtained, and does not repeat them here.
Fig. 3-1-Fig. 3-5 is the schematic diagram of the polymerization sublink recovery processing procedure of the application embodiment of the invention, and is specific as follows:
Fig. 3-1 is identical with Fig. 1-1.
When the link-recovery between P1 and the P5, be example with the device A, processing procedure is as follows:
01: shown in Fig. 3-2, device A finds that the state of P1 becomes up by down, and then the initial condition of P1 is set to: Tx discarding, Rx discarding.
02: shown in Fig. 3-3, device A finds that P1 is a polymerization sublink port, P1 is added aggregation group on the exchange chip, actual four ports of P1～P4 that comprise of aggregation group on the exchange chip like this, because the state of P1 sending direction is Tx discarding, therefore P1 does not share the flow of aggregation group, but is shared by P2～P4.
03: to P5 transmit port status poll message, P5 sends response message adding after aggregation group and equipment B be arranged to Rx forwarding with the state of P5 receive direction to P1 to device A by P1.
04: as shown in Figure 3-4, device A is arranged to Tx forwarding with the state of P1 sending direction after receiving response message from P5 from P1, and the flow of aggregation group just can normally have been shared P1.
