Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, below described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under performing creative labour prerequisite, all belong to the scope of protection of the invention.
First the present invention provides a kind of method for configuring route as shown in Figure 1, the static L3VPN network of this collocation method based on shown in Fig. 2 and Fig. 3 and the networking schematic diagram of hollow subnet thereof.Refer to shown in Fig. 2 and Fig. 3, this static state L3VPN network comprises (the Serving Gateway by SGW, gateway) and NE3, NE6 composition core layer network, the convergence-level network being formed by NE3, NE6 and NE2, NE5, and the access layer network being formed by NE1, NE4 and eNodeB1 (Evolved NodeB, base station 1), eNodeB2.Wherein, NE1, NE2, NE3, NE4, NE5, NE6 are as basic element---the access node (NetElement in static L3VPN network, claim again network element node, node), in practical application scene, show as each communicating terminal, for networking provides the physical support of data message transmission, and can the certain communications function of complete independently.Particularly:
Respectively corresponding and eNodeB1, eNodeB2 communication connection of NE1, NE4, therefore in networking as two layers of access node, the two role in networking accesses for L2.NE2, NE5 correspondence converge two layers of access node NE1, NE4, therefore in networking as three layers of access node, the two role in networking is L3 access.NE3, NE6 correspondence converge three layers of access node NE2, NE5, therefore in networking as core convergent access node, the two role in networking converges for L3.
Should understand, the access node that above-mentioned static L3VPN network and hollow subnet thereof comprise only for explanation for example, the present invention can be provided with any number of different access nodes by networking according to the network planning characteristic in practical application scene, is not limited to be divided into NE1, the NE2, NE3, NE4, NE5, the NE6 that given an example above.Accordingly, the candidate's route calculating also can be adjusted according to practical application, comprises at least two candidate's routes.
Fig. 1 is the flow chart that the present invention is based on the method for configuring route of the first embodiment of static L3VPN network shown in Fig. 2 and Fig. 3.Incorporated by reference to Fig. 1～Fig. 3, the method for configuring route of the present embodiment comprises the step S11 of route calculation stages, step S12 and the step S13 in routing forwarding stage that route priority is determined the stage, particularly:
Step S11: according to the destination address of destination node, calculate at least two candidate's routes that arrive destination node from present node.
The object that above-mentioned networking communicates is that network traffics are transferred to eNodeB1 and/or eNodeB2 from SGW, therefore need on NE3 or NE6, configure route, arrives the transmission path of eNodeB1 and/or eNodeB2 in order to planning network flow.For example,
For NE3 to eNodeB1, present node is NE3, and destination node is eNodeB1 (NE1), and destination address is 10.0.8.33, and NE3 need to learn the route of NE2, NE5.That is to say, the routing diffusion that transfers to eNodeB1 that NE2, NE5 need to learn its node self to is to NE3 (also comprising other nodes direct-connected with it), so that whole e-learning is to destination address (the IP address of eNodeB1,10.0.8.33), with after this NE2, NE5 establish a communications link by L2 access node NE1 and eNodeB1, so that eNodeB1 is by convergence-level network insertion core layer network, communicate thereby obtain network traffics.
Therefore, calculating at NE3 the static routing generating is: destination address is the IP address of base station eNodeB 1, and down hop when routing forwarding is node NE2; Destination address is the IP address of base station eNodeB 1, and down hop when routing forwarding is node NE5.That is to say, network traffics have generated two paths from NE3 to eNodeB1, and a paths is to be forwarded to eNodeB1 by NE2, and another paths is to be forwarded to eNodeB1 by NE5.
Because the route priority of two routes that generate in above-mentioned computational process is identical; cannot distinguish that in two routes, which which forwards as Protection path; therefore first need to determine the route priority of at least two routes with identical object IP address; effectively forward route to choose the route that route priority is the highest as reality; the principle of technical solution of the present invention is route priority definite to be married again into the determining of the device role to access node, i.e. step S12.
Step S12: according to the device role of the next-hop node of present node at least two candidate's routes, determine the route priority of at least two candidate's routes.
In the present invention, the device role of next-hop node comprises host node and from node.Based on this, the present embodiment determines that next-hop node is that candidate's route of host node has the first priority, determines that next-hop node is to have the second priority from candidate's route of node, and the first priority is higher than the second priority.In conjunction with Fig. 2 and Fig. 3, that is to say:
In the time of networking planning in advance, selecting NE2 is that host node and NE5 are from node, for NE3 to eNodeB1, when next-hop node is that NE2 is while being host node, the route priority of the candidate's route that comprises NE3 to NE2 is the highest, for preferably forwarding route, accordingly now, the priority of the candidate's route that comprises NE3 to NE5 is minimum, is alternative forwarding route.
Wherein, in the time that networking is planned, for the device role of next-hop node, this next-hop node of how to confirm is host node or from node, the present embodiment is not limited, and those skilled in the art can arrange according to actual conditions actual needs.For example, according to the load flow of next-hop node, next-hop node be labeled as to host node or from node, that is, the next-hop node of load flow maximum be labeled as to host node, other next-hop node is labeled as from node.
Step S13: select candidate's route that route priority is the highest as preferential forwarding route, and candidate's route of selecting other is as forwarding route for subsequent use.
In conjunction with Fig. 2 and Fig. 3, that is to say, select target address is that the IP address of base station eNodeB 1 and down hop are that candidate's route of node NE2 is carried out routing forwarding.
Based on above-mentioned known, because the quantity of access node in L3VPN network is far smaller than the quantity of candidate's route, therefore while configuration, being compared to prior art workload reduces greatly, operating efficiency is able to remarkable height and configuration error rate is low, determine host node according to device role simultaneously and from node, require also not harsh to configuration personnel's professional skill.
