3rd embodiment:
In conjunction with concrete application example the application done and further annotate explanation；As shown in Figure 4, in the present embodiment, multilink bundling method provided by the invention comprises the following steps:
S401: distribute convergence device for access device；
With reference to Fig. 3, in the present embodiment, convergence device is convergence router Router, concrete, distributes convergence router Router1 and Router2 for access device C1；
S402: access device respectively and arranges multilink bundling group between each convergence device；
In arranging multilink bundling group process, the access link arranging access device supports multilink bundling function, and the access side ports arranging two convergence routers supports multilink bundling, specifically includes:
After opening of device, access device and convergence router equipment are respectively created the multilink bundling group of oneself, and each multilink bundling group is tied up into plural PoS port, becomes the member port of this multilink bundling group；
Member Link between access device and convergence router opens the link setup based on HDLC (High-levelDataLinkControl) agreement and keep-alive; the port open HDLC encapsulation of both link ends; and send out link building messages mutually; what link building messages carried is the basic datas such as port-mark and the session label information of local terminal; after the other side receives link building messages; response link setup response message; link setup response message encloses port-mark and the session identification of local terminal; after link setup initiator has successfully received response, putting local terminal state is link setup state；
Keep-alive message is sent out in the member port timing entering link setup state mutually; keep-alive message is except carrying port basis data; also carrying the mark (such as group number etc.) of local terminal place multilink bundling group, load sharing mode, smallest link activates the information such as thresholding and port speed；After recipient receives keep-alive message, enclosing the port basis data of local terminal, the group number of local terminal place binding group, load sharing mode, smallest link activates the information such as thresholding and port speed, constitutes keep-alive response message and returns to initiator；Initiator receives response message, and whether the binding group configuration comparing two ends is identical, and as identical, then putting local terminal state is activated state；If link setup both sides have been enter into activated state, then this physical link activates；In order to avoid occurring that Link State shakes, the keep-alive interval that link both sides are arranged is identical；
Some link sequential activation in multilink bundling group, reach the activation amount threshold (minimum activation thresholding) of binding group, and the protocol status just putting binding group is activated state；According to load sharing mode, all activated link in binding group both participates in flow and forwards；
In actual applications, with reference to Fig. 3, this step includes:
Access device C1 selects two groups of PoS ports, PoS1, PoS2, PoS3 mono-group, dock with PoS11, PoS12, PoS13 port of convergence router Router1, another set port PoS4, PoS5, PoS6, dock with PoS14, PoS15, PoS16 port of convergence router Router2；PoS port at same veneer, it addition, the PoS8 that Router1 selects a road port PoS7 and Router2 docks, can not form HDLC isochronous communication channel；
Creating two bindings group Pg1 and Pg2, Pg1 on access device C1 and tie up inbound port PoS1, PoS2, PoS3, Pg2 ties up inbound port PoS4, PoS5, PoS6；Convergence router Router1 creates binding group Pg3, ties up inbound port PoS11, PoS12, PoS13；Convergence router Router2 creates binding group Pg4, ties up inbound port PoS14, PoS15, PoS16；Link between Pg1 and Pg3 constitutes the link between HDLC multilink bundling group BD1, Pg2 and a Pg4 and constitutes a HDLC multilink bundling group BD2；The binding group attribute that the configuration of multilink bundling group is identical, such as load sharing mode is set to packet-by-packet, and smallest link activates thresholding and is set to 3。
HDLC encapsulation is opened, namely at PoS1-PoS11, PoS2-PoS12 at the two ends of every physical link, PoS3-PoS13, PoS4-PoS14, PoS5-PoS15, encapsulating HDLC protocol on the port of PoS6-PoS16, PoS7-PoS8 link respectively, each link starts to send out mutually link building messages。Concrete, for PoS1-PoS11 link, what carry in the link building messages that PoS1 sends is the basic datas such as port index and the session label of PoS1；PoS11 resolves after receiving this message, preserves counter-party information, and then bag, the port index of attachment PoS11 and session label are returned in assembling response；PoS1 receives after this link setup response returns bag, and putting local terminal state is link setup state；Opposite to each other, PoS11 also can initiate the link setup request of identical content to PoS1, once receive the response message of PoS1, PoS11 is just set to link setup state local terminal state；After entering link setup state; link setup both sides regularly send out keep-alive message mutually; to confirm that link can be used; PoS1 in the PoS11 keep-alive message sent except carrying the basic datas such as port index and the session label of PoS1; also adhere to the label of the port place binding group Pg1; the load sharing mode of Pg1, the smallest link of Pg1 activates the port speed information of thresholding and PoS1；After PoS11 receives this message, preserving client information and organize bag response, response message adheres to port index and session label, the label of the port place binding group Pg3 of PoS11, the load sharing mode of Pg3, the smallest link of Pg3 activates the port speed information of thresholding and PoS11；After PoS1 receives response message, compare both sides place binding group Pg1, the load sharing mode of Pg3 activates the whether identical of thresholding configuration with smallest link, and as identical, the state putting local terminal PoS1 is activated state；Opposite to each other, PoS11 also regularly can initiate the keep-alive message of identical content to PoS1, once receive response comparison success, just putting PoS11 port is activated state。Both sides' port has been enter into state of activation, and this link is with regard to successful activation, it is possible to participate in assignment of traffic and forwarding。Similarly, PoS2-PoS12, PoS3-PoS13, PoS4-PoS14; PoS5-PoS15, PoS6-PoS16 link each link setup keep-alive, link activation then participates in flow and forwards; if there being one end not activate, this link is just unavailable, and flow can be assigned to other active link。PoS7-PoS8 link is owing to being not engaged in multilink bundling; the binding group information carried in their keep-alive message is invalid value 0; as long as link both sides can be properly received the keep-alive response message of the other side, binding group information 0 therein is also considered as comparison success, can by state transition to activated state。
Three Member Links in binding group activate one by one, and active link number reaches the minimum activation thresholding 3 of binding group, just transfers the protocol status of binding group to activated state, proceeds by traffic distribution。Assume that the multilink bundling group of BD1 takes the lead in transferring activated state to, then BD1 is started traffic as current primary binding group and forward。In group, all activated member is all as active link, and performing data send, and Router1 becomes current work equipment。And after BD2 slightly becomes activated state late, becoming current reserve link binding group, Router2 also just becomes current stand-by equipment。
S403: interactive link binding group information between each convergence device, determines primary link binding group and standby link binding group according to multilink bundling group information；
This step is the masterslave switchover in order to realize main/slave link binding group, between convergence device Router1 and the convergence device Router2 at reserve link binding group place at active link binding group place, open active and standby negotiation functionality, by HDLC physical link, notice mutually the working condition of local terminal binding group。Carry out the equipment of active and standby negotiation according to whether the priority of the current standby binding group of active and standby election regulation analysis is higher than primary binding group, if, then standby binding group is set to current primary binding group, primary binding group is set to current standby binding group, and switches；Otherwise, continue according to active and standby election regulation timing report mutually, it is judged that whether the priority of current standby binding group is higher than primary binding group。Specific as follows:
Two convergence router equipment are separately turned on active and standby negotiation functionality, and select a road HDLC physical link logical as communication；
Two equipment timings send HDLC negotiation packet to the other side；Negotiation packet carries the attribute information of basic data and the local terminal binding group sending port, the attribute information of local terminal binding group is effective field that active and standby election regulation is required, including local terminal binding group group number, local terminal system priority, local terminal arrange smallest link activate thresholding, local terminal binding group bandwidth, local terminal binding group current activation state etc.；
Opposite end resolves after receiving negotiation packet, compares one by one according to the attribute information of the active and standby election regulation election field to parsing and local terminal binding group, it is determined that the height of priority, selects primary binding group。And in consulting response message, enclose attribute information and the election results of local terminal binding group；
Local terminal receives the negotiation response message of opposite end transmission and resolves, the election field returned opposite end according to active and standby election regulation and the election field of local terminal compare, confirm that local terminal is main and election results field is 0 if comparing, represent that the activestandby state of this negotiation is identical with current active and standby binding group duty, keep active and standby binding group state constant, continue to carry out flow forwarding in primary binding group, periodically perform above-mentioned steps；If comparing confirmation local terminal to resolve to 1 for standby and election results field; then perform pretection switch; active and standby binding group carries out pretection switch; standby binding group is set to current primary binding group; primary binding group is set to current standby binding group; primary binding group after switching carries out flow forwarding, periodically performs above-mentioned steps；If the election results that the result that local terminal confirms and opposite end return are also inconsistent, namely compare and confirm that local terminal is main and election results field is 1, or comparing confirmation local terminal is 0 for standby and election results field, then again send active and standby negotiation packet, if continuous three negotiation results all have objection, then perform Forced Switch；
When having Member Link to break down in primary binding group, primary binding group receives fault notification event, recalculates the election field of local terminal, carries out active and standby negotiation；
The active and standby election regulation used in negotiations process is mainly included in following five according to priority by high and low: (1) judges whether the state of activation field of active and standby binding group is all activated state, if not, then in active and standby binding group, the priority of the multilink bundling group being active is higher than the priority of the multilink bundling group being in unactivated state；(2) the active link total bandwidth of active and standby binding group is compared, if unequal, then in active and standby binding group, the priority of the binding group that the priority of the binding group that active link total bandwidth is higher is relatively low higher than active link total bandwidth；(3) system priority of active and standby binding group is compared, if unequal, then in active and standby binding group, the priority of the binding group that the priority of the binding group that system priority is higher is relatively low higher than system priority；(4) compare the number of the member port being active in active and standby binding group, if unequal, then, in active and standby binding group, activate the priority of the more binding group of member port number higher than the priority activating the relatively low binding group of member port number；(5) above strategy all can not differentiate height, then the priority of active and standby binding group is equal, and current primary binding group is decided to be primary binding group。
In actual applications, with reference to Fig. 3, this step includes:
Router1, Router2 open active and standby negotiation, and after PoS7-PoS8 passage keep-alive activates, PoS7 gets started and regularly sends negotiation packet。Negotiation packet, except the port basis data carrying PoS7, also encloses the label of local terminal binding group Pg3, local terminal system priority, and the smallest link of Pg3 activates thresholding, the link total bandwidth of Pg3, the current activation state of Pg3；
PoS8 receives the PoS7 negotiation packet sent and resolves, and according to active and standby election regulation, the respective field of the election field of the opposite end BD1 parsed He this equipment BD2 is compared one by one, compares state of activation, and two ends are activated state；Relatively binding group bandwidth, it has been found that three the active link bandwidth summations of BD1, three active link bandwidth more than BD2 and, thereby confirm that current active link binding group BD1 election is active link binding group, BD2 is reserve link binding group；It is 0 that PoS8 arranges election results field, and together organizes bag together with the basic data of the port and the election field of BD2, returns to PoS7 and holds consultation response。PoS7 receives the response message that opposite end sends, resolve the election field of opposite end, make comparisons with the election field of local terminal, confirm local terminal BD1 three active link bandwidth summations, three active link bandwidth more than opposite end BD2 and, it is thus determined that local terminal is consult active link binding group out, this result is consistent with the election results field 0 that the opposite end parsed provides, confirm that result is effective, namely BD1 is active link binding group, BD2 is reserve link binding group, the main/slave link binding group duty keeping current is constant, proceeds flow and forwards。Intervalometer is held consultation to transmission negotiation packet again；
Link building messages, keep-alive message and the negotiation packet form used in the present invention; the information field to standard HDLC message format is adopted to be extended; be extended for the combination of Protocolcode+PdutyPe+Data, concrete structure as it is shown in figure 5, wherein it should be understood that
Address, this field fills out 0x8F；
Control, this field fills out 0x00；
Protocolcode, this field fills out 0x8035；
