Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
The embodiment of the invention has proposed a kind of method for synchronous of Link State Protocol Data Unit, realizes reducing the LSP inundation for the TRILL network, saves the purpose of bandwidth resources; Application scenarios schematic diagram take Fig. 1 as the embodiment of the invention can comprise a plurality of RB equipment in this TRILL network.
As shown in Figure 3, the method for synchronous of this Link State Protocol Data Unit can may further comprise the steps:
In the embodiment of the invention, the LSP after the path that each the RB equipment in the TRILL network is directly set according to the TRILL shortest path in a network is upgraded synchronously specifically comprises:
More news one, situation two and situation three (corresponding situation is described in subsequent process) occur for LSP, RB equipment in the TRILL network is after obtaining shortest path tree, with from as the root node of shortest path tree, to shortest path tree that self directly links to each other on other RB equipment transmission renewal after LSP; And because each the RB equipment in the TRILL network all need to be with from as the root node of shortest path tree, send LSP after upgrading according to shortest path tree, thus can be so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize LSP synchronously.
More news four (corresponding situation is described in subsequent process) occurs for LSP, the LSP of RB equipment in the TRILL network after receiving the renewal that other RB equipment (take RB equipment 1 as example) sends, and after obtaining shortest path tree, with from as the root node of shortest path tree, the LSP after other RB equipment transmission renewal on outside the RB equipment 1 and the shortest path tree that self directly links to each other; And because each the RB equipment in the TRILL network all need to be with from as the root node of shortest path tree, send LSP after upgrading according to shortest path tree, thus can be so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize LSP synchronously.
In the embodiment of the invention, because the LSDB of ISIS is that whole network is carried out synchronous, therefore in the TRILL network, each RB equipment is based on SPF(Shortest Path First, SPF) shortest path tree that calculates of algorithm and LSDB is identical, for application scenarios shown in Figure 1, then directly set can be as shown in Figure 4 for the TRILL shortest path in a network.
Further, each RB equipment need to be according to the LSP after this shortest path tree transmission renewal after acquisition TRILL shortest path in a network is directly set; For shortest path tree shown in Figure 4, then send the path of the LSP after upgrading as shown in Figure 5; RB6 is when knowing that LSP occur to upgrade, and the LSP after will upgrading according to shortest path tree sends to RB1; During the LSP of RB1 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB7; During the LSP of RB7 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB2, RB3, RB4; During the LSP of RB4 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB8, RB9; During the LSP of RB9 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB5.
Again for example, for shortest path tree shown in Figure 4, RB7 is when knowing that LSP occur to upgrade, and the LSP after will upgrading according to shortest path tree sends to RB1, RB2, RB3, RB4; During the LSP of RB1 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB6; During the LSP of RB4 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB8, RB9; During the LSP of RB9 after receiving renewal, the LSP after will upgrading according to shortest path tree sends to RB5.
In sum, each RB equipment transmits LSP after the renewal by shortest path tree, can reduce the quantity of the LSP that transmits in the TRILL network, and save the bandwidth resources in the TRILL network; And since can timed sending between all neighbours of ISIS CSNP(Complete Sequence Numbers Protocol Data Unit, complete sequence number protocol element) message, thereby can guarantee that the whole network LSP's is consistent.
Concrete, in order to guarantee the consistent of the whole network LSP, DRB can periodically send CSNP(its comprise local all LSP summary info (as sender, sequence number, verification and, the residue time limit)), to guarantee that all LSDB are consistent on the link.Wherein, each RB equipment is by more local LSDB and the CSNP that receives; If this locality does not have certain LSP or certain LSP older (sequence number is larger among the CSNP that namely receives), then RB equipment is by PSNP(Partial Sequence Numbers Protocol Data Unit, partial sequence number protocol element is carried out LSP request or affirmation when asynchronous for LSDB) ask this LSP to DRB; If there is certain LSP this locality but does not have among the CSNP, perhaps local certain LSP upgrades (sequence number is less among the CSNP that namely receives), and then RB equipment is initiatively to DRB this LSP that floods.
In the embodiment of the invention, the process that LSP occurs to upgrade specifically includes but not limited to:
Situation one, when having new terminal equipment to join the TRILL network on the RB equipment or having terminal equipment to leave the TRILL network, this RB device learns LSP upgrades.Afterwards, this RB equipment need to obtain the TRILL shortest path in a network and directly set, LSP after will upgrading according to shortest path tree sends to other RB equipment, obtain the TRILL shortest path in a network during by the LSP of other RB equipment after receiving renewal and directly set, and send LSP after upgrading according to shortest path tree; Further because the LSP of each RB equipment after all need to send upgrading according to shortest path tree, thereby can be so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize LSP synchronously.
For example, new MAC(Media Access Control is arranged on RB6, medium access control) add fashionable, showing has new terminal equipment to join the TRILL network on the RB6, therefore RB6 knows that LSP upgrades, and the LSP that will directly set after will upgrading according to the TRILL shortest path in a network sends to RB1, concrete transmission path as shown in Figure 5, the subsequent transmission process does not repeat them here.
Situation two, when the link between RB equipment and other RB equipment disconnects, RB device learns LSP upgrades.Afterwards, RB equipment need to obtain the TRILL shortest path in a network and directly set, LSP after will upgrading according to shortest path tree sends to other RB equipment, obtain the TRILL shortest path in a network during by the LSP of other RB equipment after receiving renewal and directly set, and send LSP after upgrading according to shortest path tree; Further because the LSP of each RB equipment after all send upgrading according to shortest path tree, thereby can be so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize LSP synchronously.
In the embodiment of the invention, when the link between RB equipment and other RB equipment disconnected, TRILL shortest path in a network directly tree can change; And before shortest path tree changed, each RB equipment can send according to the shortest path tree before changing the LSP after upgrading; After shortest path tree changed, each RB equipment can send according to the shortest path tree after changing the LSP after upgrading.
Concrete, the RB equipment in the TRILL network need to be according to the LSP after synchronous renewal the in path of link disconnection shortest path tree before before the link between this equipment and other RB equipment disconnects; And, after the link between this equipment and other RB equipment disconnects, the LSP after the path of the shortest path tree after need to disconnecting according to link is upgraded synchronously.
Situation three, when there being RB equipment to join the TRILL network, and when newly the RB equipment (such as RB10) of adding was for the neighbours of certain RB equipment (such as RB6) (being that RB equipment is set up neighborhood with the RB equipment that newly joins the TRILL network), then this RB6 knew that LSP upgrades.Afterwards, RB equipment need to obtain the TRILL shortest path in a network and directly set, LSP after will upgrading according to shortest path tree sends to other RB equipment, obtain the TRILL shortest path in a network during by the LSP of other RB equipment after receiving renewal and directly set, and send LSP after upgrading according to shortest path tree; Further because the LSP of each RB equipment after all send upgrading according to shortest path tree, thereby can be so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize LSP synchronously.
In the embodiment of the invention, when having RB equipment (RB10) to join the TRILL network, TRILL shortest path in a network directly tree can change; And before shortest path tree changes, LSP after the neighbours (RB6) of the RB equipment (RB10) that should newly add can upgrade according to the transmission of the shortest path tree before the variation, and receive that each the RB equipment of the LSP after the renewal can be according to the LSP that changes after shortest path tree before sends renewal; After shortest path tree changes, LSP after the neighbours (RB6) of the RB equipment (RB10) that should newly add can upgrade according to the transmission of the shortest path tree after the variation, and receive that each the RB equipment of the LSP after the renewal can be according to the LSP that changes after shortest path tree afterwards sends renewal.
Concrete, the RB equipment in the TRILL network before new RB equipment joins the TRILL network, the LSP after need to upgrading synchronously according to the path that new RB equipment joins the shortest path tree before the TRILL network; And, after new RB equipment joins the TRILL network, the LSP after need to upgrading synchronously according to the path that new RB equipment joins the shortest path tree after the TRILL network.
Situation four, when RB equipment is received from the LSP after the renewal of other RB equipment, then this RB device learns LSP upgrades.Afterwards, this RB equipment need to obtain the TRILL shortest path in a network and directly set, LSP after will upgrading according to shortest path tree sends to other RB equipment (send to this RB equipment the LSP after upgrading RB equipment except), obtain the TRILL shortest path in a network during by the LSP of other RB equipment after receiving renewal and directly set, and send LSP after upgrading according to shortest path tree; Because the LSP after each RB equipment all send to upgrade according to shortest path tree, thereby so that each the RB equipment in the TRILL network all receives the LSP after the renewal, realize that LSP is synchronous.
The technique scheme of the embodiment of the invention can also with the MESH GROUP(grid group of ISIS) use simultaneously, enabling on the RB equipment of MESH GROUP according to MESH GROUP path transmission LSP, do not enabling on the RB equipment of MESH GROUP according to shortest path tree transmission LSP.
Concrete, RB equipment is by judging whether self disposes MESH GROUP; When disposing MESH GROUP on the RB equipment, the LSP after this RB equipment will upgrade sends to the RB equipment among the MESH GROUP; When not disposing MESH GROUP on the RB equipment, the LSP after this RB equipment will upgrade according to shortest path tree sends to other RB equipment, namely carries out the technical scheme that the embodiment of the invention provides, and this process no longer repeats to give unnecessary details at this.
The schematic diagram of directly setting for TRILL shortest path in a network shown in Figure 4, suppose at RB1 and RB6 configuration MESH GROUP, in the MESH GROUP that RB1 disposes, comprise RB6, RB7, RB8, in the MESH GROUP that RB6 disposes, comprise RB1, RB2, RB3, RB4, RB5; Then concrete transmission path as shown in Figure 6; RB6 is when knowing that LSP occur to upgrade, owing to dispose MESH GROUP on the RB6, so the LSP of RB6 after will upgrading sends to RB1, RB2, RB3, RB4, RB5; During the LSP of RB1 after receiving renewal, owing to dispose MESH GROUP on the RB1, so the LSP of RB1 after will upgrading sends to RB7, RB8; In addition, because RB9 is in MESH GROUP, so RB9 need to be according to the LSP of shortest path after the tree transmission is upgraded, and namely during the LSP of RB4 after receiving renewal, the LSP after upgrading sent to RB9.
Based on the inventive concept same with said method, the invention allows for a kind of synchronizer of Link State Protocol Data Unit, be applied to comprise in the multilink transparent interconnection TRILL network of a plurality of routing bridge RB equipment, and described synchronizer is as the RB equipment in the described TRILL network, as shown in Figure 7, this RB equipment comprises:
