Embodiment
The embodiment of the present invention provides a kind of pseudo-linear flow rate control method and relevant device, to avoid forming loop between the VPLS sub-network of different classification in HVPLS network.
The present invention program is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the embodiment of a part of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
Below by specific embodiment, be described in detail respectively.
Please refer to Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of pseudo-linear flow rate control method.
Embodiment of the present invention method is applied to HVPLS network, and described HVPLS network comprises the first VPLS network and the second VPLS network.The inside of the first VPLS network and the second VPLS network is full connection, that is: setting up between any two network nodes in described first VPLS network has Hub PW; Set up between any two network nodes in described second VPLS network and have Hub PW.At least two Spoke PW (accessing pseudo-line) are adopted to connect between first VPLS network and the second VPLS network, wherein, set up between at least one network node respectively and in described second VPLS network of two network nodes in described first VPLS network and access pseudo-line Spoke PW.Described two network nodes comprise first network node and second network node.Said network node can be specifically PE equipment.
In some embodiments of the invention, said HVPLS network can be as shown in Figure 1.In Fig. 1, first VPLS network on the right comprises four NPE (Network Provider PE, network core PE), and use NPE1 respectively, NPE2, NPE3, NPE4 represent, setting up between any two NPE has Hub PW.Wherein, NPE1, NPE2 play switch (Switch), for being connected with the second VPLS network, also can be described as SPE (Switch PE), representing respectively in figure with S/NPE1 and S/NPE2.Optionally, S/NPE1 and S/NPE2 is connected to CE (Custom Edge, customer edge) equipment, and such as, S/NPE1 and CE1 connects, and S/NPE1 and CE2 connects.
In Fig. 1, second VPLS network on the left side comprises four common PE equipment, and use PE1 respectively, PE2, PE3, PE4 represent, setting up between any two PE has Hub PW.
Spoke PW is adopted to connect between first VPLS network and the second VPLS network.Concrete, PE3 and PE4 respectively dual homed is connected to S/NPE1 and S/NPE2 of the first VPLS network, and setting up between PE3 and PE4 and S/NPE1 and S/NPE2 has four Spoke PW.
As Fig. 1, S/NPE1 and S/NPE2 are connected respectively by Spoke PW and PE1, and in prior art, Spoke PW and Hub PW does not observe horizontal segmentation principle, can unrestrictedly intercommunication, therefore, may form loop between S/NPE1 and S/NPE2 and PE1.Such as, PE3 is transmitted to the message of S/NPE1 by Spoke PW, and can be transmitted to S/NPE2 by S/NPE1 by Hub PW, this message can be transmitted to PE3 by Spoke PW by S/NPE2 again.In like manner, also loop may be formed between S/NPE1 and S/NPE2 and PE2.For solving this problem, embodiments provide a kind of pseudo-linear flow rate control method.
Please refer to Fig. 2 a, the pseudo-linear flow rate control method of the one that the embodiment of the present invention provides can comprise:
110, the pre-configured multiple isolation group of first network node, wherein, isolation group described in each comprises at least one Hub PW, and each Hub PW can only belong to an isolation group; And, needing the relation that is associated between the isolation group of intercommunication and Spoke PW.
The embodiment of the present invention, by controlling the flow of PW, avoids the formation of loop.For realizing flow control, can configure multiple isolation group in advance on first network node such as S/NPE1 or S/NPE2, each isolation group comprises at least one Hub PW, and each Hub PW can only belong to an isolation group.The meaning of isolation group is, the Hub PW in isolation group, and acquiescence and Spoke PW isolate, and can not mutually forward.
In the embodiment of the present invention, the isolation group of intercommunication and the relation that is associated between Spoke PW can also needed.After the relation that is associated, the Spoke PW intercommunication that the Hub PW in isolation group can and be associated with this isolation group, and can not with other Spoke PW intercommunication.Article one, Spoke PW can have incidence relation with one or more isolation group.
The isolation group of above-mentioned configuration and incidence relation etc. are stored in advance in S/NPE1 or S/NPE2 as configuration data.
When 120, receiving the first message by a Spoke PW, judge whether to there is the isolation group be associated with a described Spoke PW, if existed, the identifier of the described isolation group be associated is added in the heading of described first message.
Wherein, a Spoke PW can be any one the Spoke PW in described Spoke PW.
Spoke PW processing module is equipped with in S/NPE1 or S/NPE2, and Hub PW processing module.
When S/NPE1 receives the first message by a Spoke PW, when Spoke PW1 such as by being connected with PE3 receives the first message from PE3, Spoke PW processing module can pass through query configuration data, judge whether to there is the isolation group be associated with Spoke PW1, the isolation group be associated can have one or more.If there is the isolation group be associated with Spoke PW1, then the identifier of the isolation group this be associated adds in the first message, if there is multiple isolation group be associated, is then all added in the first message by the identifier of multiple isolation group be associated.If there is no the isolation group be associated with Spoke PW1, then do not need to carry out more processing to the first message.The first message after the process of Spoke PW processing module, is passed to Hub PW processing module.
When 130, forwarding described first message to a Hub PW, confirm the identifier whether having isolation group in the heading of described first message.
Wherein, a Hub PW can be any one the Hub PW in described Hub PW.
Hub PW processing module is used for the message transmission of Spoke PW processing module come, and is forwarded to destination network node by Hub PW.When Hub PW processing module receive that Spoke PW processing module is sent, need the first message being forwarded to Hub PW time, first confirm whether the heading of the first message has the identifier of isolation group.To carry out corresponding flow control according to isolation group.
If have identifier in the heading of 140 described first messages, judge whether a described Hub PW belongs to isolation group corresponding to described identifier, if belong to, then give a described Hub PW by described first message repeating, if do not belong to, then abandon described first message;
If there is no identifier in the heading of described first message, judge whether a described Hub PW has affiliated isolation group, if do not have, then give a described Hub PW by described first message repeating, if having, then abandon described first message.
Visible, if there is the identifier of at least one isolation group in the heading of the first message, then, give the Hub PW included by this at least one isolation group by the first message repeating.Such as, suppose that the first isolation group comprises the Hub PW3 between S/NPE1 and NPE3, and the first isolation group and Spoke PW1 have incidence relation, then the identifier of the first isolation group can be carried in the heading of the first message, so, first message by Hub PW processing module by the Hub PW3 between S/NPE1 and NPE3, can be transmitted to NPE3.
Again such as, second isolation group comprises the Hub PW between S/NPE1 and S/NPE2, and the second isolation group and Spoke PW1 do not have incidence relation, then the identifier of the second isolation group can not be carried in the heading of the first message, so the first message can not be transmitted to Hub PW between S/NPE1 and S/NPE2 by Hub PW processing module.So just can avoid forming loop between S/NPE1 and S/NPE2 and PE3.
If do not comprise the identifier of any isolation group in the heading of the first message, then the first message repeating can be given the Hub PW not belonging to any isolation group by Hub PW processing module.Such as, the Hub PW4 between S/NPE1 and NPE4, if do not belong to any isolation group, and does not comprise the identifier of any isolation group in the first message, then, the first message as in prior art, can be forwarded to the Hub PW between S/NPE1 and NPE4.
Above, the flow control from Spoke PW to Hub PW direction is illustrated.
Embodiment of the present invention method, can also comprise the flow control from Hub PW to Spoke PW direction.Concrete, as shown in Figure 2 b, said method can also comprise:
When 150, receiving the second message by a Hub PW, the identifier of a described Hub PW is added in the heading of described second message.
When S/NPE1 receives the second message by Hub PW, Hub PW3 such as by being connected with NPE3 receives the second message from NPE3, or, when receiving the second message from S/NPE2 by the Hub PW1 be connected with S/NPE1, Hub PW processing module processes the second message, adds the identifier of Hub PW3 or Hub PW1 in the heading of the second message.Then, the second message is passed to SpokePW processing module.
When 160, forwarding described second message to a Spoke PW, confirm whether a described Spoke PW has the isolation group of existing association.
Spoke PW processing module is used for the message transmission of Hub PW processing module come, and is forwarded to destination network node by Spoke PW.When Spoke PW processing module needs to forward the second message to Spoke PW, first obtain the identifier of the Hub PW carried from the heading of the second message.
If 170 described Spoke PW have the isolation group be associated, judge a described Hub PW whether belong to described in the isolation group that is associated, if belong to, described second message is transmitted to a described Spoke PW, noly not belong to, then abandon described second message;
If the isolation group that a described Spoke PW is not associated, judge whether a described Hub PW has affiliated isolation group, if do not have, then described second message is transmitted to a described Spoke PW, if having, then abandons described second message.
The Hub PW carried for the second message is Hub PW3.Suppose that Spoke PW1 between PE3 and S/NPE1 and the first isolation group have incidence relation, and Hub PW3 belongs to the first isolation group, then, the second message is transmitted to Spoke PW1 by Spoke PW processing module, and the second message arrives at PE3 by Spoke PW1.
The Hub PW carried for the second message is Hub PW1.Suppose that a Spoke PW and the second isolation group belonging to Hub PW1 do not have incidence relation, then, Spoke PW processing module directly can abandon this second message.
The Hub PW carried for the second message is Hub PW4 (the Hub PW between S/NPE1 and NPE4), suppose that Hub PW4 does not belong to any isolation group, then, Spoke PW processing module can as in prior art, second message is transmitted to all Spoke PW, such as, is transmitted to the Spoke PW1 between PE3, meanwhile, the Spoke PW3 between PE4 is also transmitted to.
Above, the flow control from Hub PW to Spoke PW direction is also illustrated.
