Embodiment
In order to improve provider backbone bridging (Provider Backbone Bridge, be called for short: message transmissions efficiency PBB), make BCB fast needed BEB object message to be sent to BEB, and the port of BCB side can be too not congested, the main thought of the scheme of embodiment of the present invention design can be referring to Fig. 2, by BEB, the message configuration information of self is sent to BCB, here said message configuration information is for limiting object message characteristic of correspondence that BEB will receive.
Be exemplified below: suppose to have configured on certain BEB a VSI (Virtual Switch Interface, virtual switch interface) example (this example comprises I-SID and the B-VLAN with one group of corresponding relation), port e1 binding in this VSI example and Fig. 2, this port e1 is the port of BEB for being connected with BCB, so just represent, BEB receives only when BCB transmits and meets the message of above-mentioned I-SID and B-VLAN at port e1, this message can be called to object message (being the message that BEB wants reception).BEB just can send to BCB by above-mentioned I-SID and B-VLAN, and this I-SID and B-VLAN just can be called message configuration information.
In BCB side, by the message configuration information transmitting according to BEB, from the mass data message receiving, to select and meet the message that message configuration information requires, this message is that BEB wants the object message receiving; This object message is sent to BEB by BCB.
Be exemplified below: BCB receives two messages, each message carries I-SID and B-VLAN, BCB is by these information and the message configuration information comparison that receives in advance BEB transmission so, the I-SID of one of them message and B-VLAN are all identical with I-SID and B-VLAN in message configuration information, BCB just confirms that this message is the object message that BEB will receive, and is sent to BEB by it by the port c1 in Fig. 2; And the B-VLAN of another message is identical with the B-VLAN in message configuration information, but both I-SID differences, and BCB can determine that this message is not the object message that BEB will receive accordingly, is abandoned.
Can pass through compared with the prior art as follows, the advantage of above-mentioned embodiment of the present invention scheme is described: suppose that BCB receives a large amount of data messages, taking three data messages as example, the I-SID of the first message is identical with the corresponding informance in above-mentioned message configuration information with B-VLAN, the I-SID of the second message is identical from message configuration information and B-VLAN is different, and the B-VLAN of the 3rd message is identical from message configuration information and I-SID is different.So, if carry out filtering packets according to of the prior art with B-VLAN, only by the BEB that sends to identical B-VLAN, will send to so BEB the first message and the 3rd message, abandon the second message; In this case, the port c1 of BCB may be more and congested due to message, and the message neither BEB wanted of the 3rd message; If but the scheme of the embodiment of the present invention, BCB will only send the first message to BEB, not only further reduce the message amount at port c1 place, alleviate congestion condition, and accurately the object message of BEB needs being sent to BEB, this all can improve message transmissions efficiency.
On the basis of the above-mentioned scheme thinking of introducing the embodiment of the present invention, following by introducing in detail the specific implementation of the embodiment of the present invention, in conjunction with Fig. 3, the method shown in Fig. 3 can comprise the steps:
301, BEB opens intelligent congestion prevention function.
Wherein, if BEB can carry out above-mentioned processing, such as the message configuration information of self is sent to BCB by BEB, to make BCB carry out accordingly packet filtering, so just this can be called to " the intelligent congestion prevention function of BEB ".In concrete enforcement, whether BEB can be opened to optional configuration of intelligent congestion prevention function setting, in the time that BEB does not configure intelligent congestion prevention function, BEB is identical with common BEB, can not send message configuration information to BCB; In the time that BEB configures intelligent congestion prevention function, can carry out the flow process of the embodiment of the present invention.The present embodiment follow-up is all to start described message handling process on the basis of above-mentioned intelligent congestion prevention function at BEB.
Certainly optional, BEB also can directly be arranged to have intelligent congestion prevention function.
302, BEB obtains the message configuration information of described BEB self.
In the present embodiment, the message configuration information of BEB self, is the object message characteristic of correspondence that will receive for limiting BEB.This message configuration information can comprise: backbone network srvice instance mark I-SID and the corresponding BVLAN of object message.In conjunction with referring to Fig. 4, BEB can comprise multiple ports, for example port e1, port e2 and port e3, and e1 is the port for connecting BCB; BEB has configured a VSI example, this VSI example comprises B-VLAN and the I-SID with corresponding relation, BEB is by this VSI example and port e1 binding, carry the B-VLAN of above-mentioned VSI example and the message of I-SID for showing that this port e1 can only receive, the message that meets this condition is called the object message of BEB simultaneously.
In another embodiment, above-mentioned message configuration information can also comprise: the dispatching message parameter that the bridge MAC Address of BEB equipment and dissimilar message are corresponding, this dispatching message parameter is for representing dispatching priority and/or the weight index of dissimilar message.
Be exemplified below: the message of supposing to have three types, be clean culture to PBB message, the multicast of BEB or be broadcast to PBB message and the non-PBB message of BEB, can on BEB, configure the dispatching message parameter of this three types message, such as, the dispatching message parameter of the present embodiment can comprise that the weight (weighted value) using in sp (dispatching priority) and/or weighting loop scheduling algorithm (Weighted Round Robin is called for short WRR) scheduling is weight parameter; For example queue A is set to sp, queue B is set to 15, queue C is set to 1, if the bandwidth of the c1 port of BCB is total up to 100M so, A, B, these three kinds of messages of C have all sent the flow of 50M, so according to above-mentioned dispatching message parameter, should priority allocation to queue A50M, remaining 50M bandwidth, queue B and queue C dispatch according to the ratio of 15:1, be that queue B assigns to 47M left and right, queue C assigns to 3M left and right.
It should be noted that, the setting of the dispatching message parameter of three kinds of above-mentioned messages is only to enumerate a kind of optional mode, in concrete enforcement, can different scheduling parameter need to be set according to actual transmissions, such as in the time that " non-PBB message " is more important for BEB than " multicast or be broadcast to the PBB message of BEB ", also weight parameter that can " non-PBB message " is set to 15, the weight parameter of " multicast or be broadcast to the PBB message of BEB " is set to 1, and (this is for example certainly, in concrete enforcement, the numerical value of weight parameter can change according to actual conditions).In addition, arranging of dispatching message parameter can be to arrange under the overall situation, also can under port, arrange.In conjunction with Fig. 4, overall situation setting refers to, and all of the port of BEB (comprising e1, e2 and e3) all can be set to identical dispatching message parameter, while receiving message, is also according to embodiment setting recited above such as port e2; Refer to and arrange under port, such as only port e1 being arranged to above-mentioned scheduling arrangement, may be different from port e1 the arranging of dispatching message of port e2.
In yet another embodiment, above-mentioned message configuration information can also comprise: PBB pattern information, described PBB pattern information is used for representing that object message is PBB message or non-PBB message.
Be exemplified below: an option that can configure can be set on BEB equipment, and whether certain port that can configure BEB opens " PBB pattern "; If be set to PBB pattern, represent that this BEB, only as BEB equipment, receives only PBB message; If be configured to non-PBB pattern, represent that this BEB can receive PBB message and also can receive non-PBB message.
In this step, BEB will obtain above-mentioned message configuration information, obtain manner can be, on BEB, be provided with Link Layer Discovery Protocol (link layer discovery protocol, be called for short: LLDP) module, this LLDP module can be collected the message configuration information of local terminal BEB equipment, and these information are assembled into type/length/value (type/length/value, TLV) information, and by this TLV Information encapsulation in LLDP message.
303, message configuration information is sent to BCB by BEB.
In the present embodiment, LLDP message is sent to BCB by BEB, carries the message configuration information that above-mentioned BEB gathers in this LLDP message.In concrete enforcement, BEB can regularly send LLDP message, and in the time that message configuration information occurs to upgrade, BEB can be sent to BCB by the message configuration information after upgrading at once.
304, BCB, according to the message configuration information receiving, generates packet filtering strategy at port.
In conjunction with shown in Figure 5, BCB is receiving after the message configuration information of BEB transmission, can be according to this Information generation packet filtering strategy, this packet filtering strategy is for making BCB select the needed object message of BEB from the mass data message receiving accordingly.For example, this packet filtering strategy can be specifically that (Access Control List is called for short: ACL) form record with Access Control List (ACL).
Because ACL is the mode for packet filtering of commonly using, the present embodiment will no longer be enumerated the concrete list of ACL, the possible condition that arranges of simple declaration ACL: for example, can arrange " if I-SID and B-VLAN do not hit the information in message configuration information simultaneously; with message configuration information in I-SID and B-VLAN incomplete same, abandon this message ", can also configure " if message is non-PBB message; abandon this message " etc., no longer enumerate.In this step, BCB will generate acl rule according to message configuration information exactly, such as, if message configuration information is " PBB pattern is " 1 " (supposing that 1 represents to receive only PBB message; 0 represents to receive non-PBB message) ", BCB just can generate the acl rule of giving an example above and " if message is non-PBB message, abandon this message " so accordingly.
In addition, BCB generate packet filtering strategy can with port binding, such as referring to Fig. 5, suppose that BCB comprises three ports, port c1 is wherein the port for being connected with BEB, port c3 is the port for being connected with other equipment (may be also another BEB), so, can be by above-mentioned packet filtering strategy and port c1 binding, be equivalent to issue above-mentioned ACL to port c1, only have the message sending to port c1 just need to filter according to this ACL, and the message sending from port c3 can filter not according to this ACL.
305, BCB receives message.
In this step, the message that BCB receives is the message of the PBBN Internet Transmission from Fig. 1, can be that another BCB from this PBBN transmits.Its message receiving comprises multiple message types, such as PBB message and non-PBB message, unicast message or multicast message etc.
306, BCB, according to packet filtering policy filtering message, obtains object message.
In above-mentioned 305, BCB has received various data messages a large amount of and that type is more, in this step, the packet filtering policy filtering message that BCB has arranged basis, from above-mentioned a large amount of messages, select BEB and wish that the message receiving is object message, can, by other packet loss, also prevent packet congestion.
307, object message is sent to BEB by BCB.
It should be noted that, in this step, BCB, in the time that the object message of selecting to obtain is sent to BEB, can utilize above-mentioned packet filtering strategy; Such as, as above, packet filtering strategy generates according to message configuration information, that just may comprise the dispatching message parameter of dissimilar message, in the time that being sent to BEB, message can send according to this parameter so, than described above, parameter is set to the queue A priority scheduling of sp, and queue B and queue C dispatch according to the ratio of WRR dispatch weight parameter.
Concrete, BCB, by how to carry out selection and the transmission of object message according to packet filtering strategy, will illustrate separately in follow-up embodiment.
Further, BCB is after receiving the message configuration information of BEB transmission, if again do not receive the message configuration information that BEB sends in Preset Time, BCB removes the message configuration information of this reception.
To describe the message configuration information how BCB sends according to BEB below in detail, and carry out select target message and send object message, i.e. step 306 in Fig. 3 and 307.Specific as follows:
First, the packet filtering strategy that BCB lateral root generates according to message configuration information, can comprise as follows:
Rule one: for the message receiving, if do not hit I-SID and the B-VLAN in message configuration information simultaneously, show that this message does not belong to BEB, abandons this message;
Rule two: for the message receiving, according to " the PBB pattern " that arrange in message configuration information, if the value of PBB pattern is " 1 ", only allow PBB message to send to BEB, abandon all non-PBB messages; If the value of PBB pattern is " 0 ", allow PBB message and non-PBB message to pass through; The PBB pattern of the present embodiment hypothesis message configuration information setting is " 0 ";
Rule three: for the message receiving, according to the destination address in message, if this destination address is the bridge MAC of the BEB that arranges in message configuration information, be shown to be the message of clean culture to BEB; If this destination address is broadcast address or multicast address, be shown to be broadcast or the multicast message to BEB; And above-mentioned " clean culture is to the message of BEB ", " broadcast or multicast are to the message of BEB " and " non-PBB message " are arranged to different dispatching message parameters, transmit dissimilar message with different dispatching priorities.The dispatching message parameter of the present embodiment hypothesis message configuration information setting is " clean culture is sp to the parameter of the PBB message of BEB, and multicast or the parameter that is broadcast to the PBB message of BEB are 15, and the parameter of non-PBB message is 1 "; The meaning of described " dispatching priority " is above, configure different scheduling resources according to the dispatching message parameter of configuration for dissimilar message, such as what give an example above, if the bandwidth of the c1 port of BCB is total up to 100M, A, B, these three kinds of messages of C have all sent the flow of 50M, so should priority allocation to queue A50M, remaining 50M bandwidth, queue B and queue C dispatch according to the ratio of 15:1, and queue B assigns to 47M left and right, and queue C assigns to 3M left and right.
Then, suppose that the BCB side of the present embodiment will receive various types of message as above, and these messages may occur at the port c1 place of BCB side congested; BCB can carry out filtering packets according to following flow process, solves congested problem, and improves message transmissions efficiency, referring to Fig. 6, comprises following processing, but does not limit the execution sequence of each step:
601, BCB does not hit I-SID and B-VLAN I-SID and the B-VLAN in (hitting identical) message configuration information simultaneously, by this packet loss;
602, BCB, according to above-mentioned rule two, allows PBB message and non-PBB message all to pass through, and does not abandon; This PBB message is the message that hits I-SID and B-VLAN;
603, BCB obtains the destination address in message, and by by the bridge MAC comparison of the BEB in this destination address and message configuration information, determines type of message;
Concrete, for the message receiving, according to the destination address in message, if this destination address is the bridge MAC of the BEB that arranges in message configuration information, be shown to be the message of clean culture to BEB; If this destination address is broadcast address or multicast address, be shown to be broadcast or the multicast message to BEB.
604, BCB, by dissimilar message, is included into corresponding message queue waiting for transmission;
Concrete, BCB can be by clean culture the message to BEB, be included into queue A; Broadcast or multicast are included into queue B to the message of BEB; Non-PBB message is included into queue C.Referring to Fig. 7, show three kinds of above-mentioned message queues.
In one embodiment, dissimilar message being included into the mode of different queue, can be that the numerical value of certain identification field in message is arranged, and sorts out message with the change by this numerical value; Such as, can enter different queues according to the dot1p priority in the message change message of coupling ACL field.
605, the BCB dispatching message parameter corresponding according to dissimilar message, with different dispatching priorities by message transmissions to BEB.
Referring to Fig. 7, with the different length of the arrow line on message queue right side, represent the dispatching priority of this message queue, the priority of " clean culture is to the message of BEB " is the highest, will preferentially meet the scheduling resource demand of message of the type; The priority of " broadcast or multicast are to the message of BEB " is taken second place, and the priority of " non-PBB message " is minimum, distributes the scheduling resource of corresponding ratio according to the ratio setting of the scheduling parameter of corresponding the type message.This order of presentation is to arrange according to the dispatching message parameter of three kinds of settings of rule above.
The application scenarios of this dispatching message priority is such as being: when BCB occurs when congested, the message of assembling has comprised the message of above-mentioned three types, so congested is likely to cause message dropping, so should preferentially transmit message relatively important for BEB, and " clean culture is to the message of BEB " is most important, because this message is clearly to BEB, " broadcast or multicast are to the message of BEB " likely this message do not belong to BEB, therefore importance is taken second place, etc.BCB will give an example according to described above, be preferably " clean culture is to the message of BEB " allocation schedule resource, to make preferentially most important message to be passed to BEB, just can when congested, reduce important message because of congested possibility of losing, even if losing may be also only not too important message, the impact like this BEB being caused is less.
The message processing method of the embodiment of the present invention, be sent to BCB by the object message feature that self side will be received by BEB, make BCB select corresponding object message to transfer to BEB according to this characteristic information, so just can meet the message requirement of BEB side, fast by needed BEB message transmissions to BEB, thereby improved message transmissions efficiency; Also eliminated the bandwidth occupancy of useless message, the effective bandwidth of having saved BCB port simultaneously.
