As previously mentioned, the method for flexible networking provided by the present invention mainly includes: at first, two interfaces of routing device are connected to the outgoing interface and the incoming interface of described two layers of transparent transmission equipment respectively; Then, described routing device is carried out corresponding configuration, making needs in the described routing device data flow that two layers of transparent transmission handle after described two layers of transparent transmission equipment, returns described routing device again and normally transmits.Fig. 2 has provided the network structure of said method embodiment, with reference to Fig. 2 described method is described in detail below.
Need to prove that two layers of transparent transmission equipment 220 include but not limited to support fire compartment wall, IPS equipment, the traffic statistics of various two layers of transparent transmission to remember expense equipment etc. shown in Fig. 2; Routing device shown in Fig. 2 210 includes but not limited to router, three-tier switch, safety product etc.
As shown in Figure 2, the incoming interface 220#1 of described two layers of transparent transmission equipment 220 is connected to the Ethernet interface 210#A of described routing device 210, and the outgoing interface 220#2 of described two layers of transparent transmission equipment 220 is connected to the Ethernet interface 210#B of described routing device 210.With the cut-in method of connecting commonly used in the existing known technology, bypass shown in Figure 2 inserts deployment way and need not to revise the existing structure of network 200, thereby can not cause extra service disconnection.
Determine described two layers of transparent transmission equipment 220 bypass insert after the described network 200, by the routing device 210 that is connected with described two layers of transparent transmission equipment 220 in the described network 200 is carried out corresponding configuration, make the data that need in the described routing device 210 two layers of transparent transmission to handle export the incoming interface 220#1 of described two layers of transparent transmission equipment 220 to from its interface 210#A, and after handling, export the described routing device 210 interface 210#B to normally to transmit from the outgoing interface 220#2 of described two layers of transparent transmission equipment 220 by corresponding two layers of transparent transmission.
Particularly, above-mentioned corresponding configuration mainly includes: at first, next jumping of data that two layers of transparent transmission of described needs is handled at configuration PBR on the described routing device 210 sends on the virtual IP address, and the data that the send to described virtual IP address described two layers of transparent transmission equipment 220 of will flowing through; Simultaneously, match with described PBR, configuring static ARP on described routing device 210 is mapped to described virtual IP address on the MAC Address of the interface 210#B that connects described two layers of transparent transmission equipment, 220 outgoing interface 220#2.Like this, the data that two layers of transparent transmission of described needs are handled by after described two layers of transparent transmission equipment 220, will be returned described routing device 210 from described interface 210#B.
Wherein, described PBR will come into force prior to the routing table in the described routing device 210 as tactful route.Like this, to match the data that two layers of transparent transmission of described needs are handled by described PBR, and the data forwarding that two layers of transparent transmission of described needs are handled jumps on virtual IP address to next of appointment, and next of described appointment jumped on virtual IP address data and will be imported described two layers of transparent transmission equipment 220.
As for how guaranteeing that the data on the described virtual IP address will correctly be sent to described two layers of transparent transmission equipment 220, solution provided by the invention is, with the IP address configuration of interface 210#A in described virtual IP address and the described routing device 210 in the same network segment.Like this, because described virtual IP address and described interface 210#A are direct-connected route (being in the same network segment), the incoming interface 220#1 that adds described interface 210#A and described two layers of transparent transmission equipment 220 is direct-connected, thereby makes the data that are directed to described virtual IP address by described PBR directly to import described two layers of transparent transmission equipment 220 from described interface 210#A.
In general, the user also can handle needs according to network operation situation and practical business, enables described PBR on the part incoming interface selectively in described routing device 210.
In addition, the user also can set the data forwarding strategy when described two layers of transparent transmission equipment 220 break down flexibly preferably by next jumping backup capabilities of described PBR.Such as, next jumping of backup of described PBR is configured to point to empty (NULL) interface, make that described routing device 210 will abandon the data of two layers of transparent transmissions processing of described needs fully when described two layers of transparent transmission equipment 220 are unreachable; Perhaps, next does not jump into the row configuration to the backup of described PBR, makes when described two layers of transparent transmission equipment 220 break down, and described routing device 210 will normally be transmitted the data of two layers of transparent transmissions processing of described needs according to routing table wherein.
To introduce the data forwarding flow process of described network 200 simultaneously in detail with reference to Fig. 3 with the data instance of input of interface 210#C from described routing device 210 and interface 210#D output from described routing device 210 below.
As shown in Figure 3, after routing device 210 in the network 200 shown in Figure 2 receives data (step S1 shown in Figure 3) from its interface 210#C, described routing device 210 will at first carry out two layers of decapsulation to described data and handle (step S2 shown in Figure 3), PBR will preferentially have an effect to determine whether described data need two layers of transparent transmission to handle (step S3 shown in Figure 3) in the described subsequently routing device 210, otherwise (carrying out step S3N1 shown in Figure 3～S3N3), is then described data redirection to be flowed through to return after described two layers of transparent transmission equipment 220 to carry out normal data forwarding and (carry out step S3Y1 shown in Figure 3～S3Y6) again to carry out normal data forwarding according to routing table in the described routing device 210.
Wherein, relevant normal data forwarding (comprises that step S3N1 shown in Figure 3～S3N3), the existing known route technology document in this area has disclosed mostly, so do not repeat them here; And relevant data how to transmit two layers of transparent transmissions processing of described needs are described in detail as follows with reference to embodiment illustrated in fig. 3.

So far, described routing device 210 will export the data that two layers of transparent transmission of described needs are handled the incoming interface 220#1 (step S3Y3 shown in Figure 3) of described two layers of transparent transmission equipment 220 to from its interface 210#A, and be packaged with the MAC Address of described interface 210#B as its link layer destination address in the data that the described IPS of needs handles.
Subsequently, described two layers of transparent transmission equipment 220 receive the data that two layers of transparent transmission of described needs are handled from its incoming interface 220#1, and it are carried out corresponding two layers of transparent transmission handle (step S3Y4 shown in Figure 3).If described data have been passed through the processing of described two layers of transparent transmission equipment 220, then it will export the interface 210#B (step S3Y5 shown in Figure 3) of described routing device 210 from the outgoing interface 220#2 of described two layers of transparent transmission equipment 220 to.
So far, the flow through forwarding process of described two layers of transparent transmission equipment 220 of the data bypass handled of two layers of transparent transmission of described needs finishes.Subsequently, after described routing device 210 receives the data of passing through two layers of transparent transmissions processing from its interface 210#B, because the link layer destination address of data is the MAC Address of local interface 210#B, therefore will carry out two layers of decapsulation (step S3Y6 shown in Figure 3) to described data, and then it directly be delivered three layers of route and normally transmit and (carry out step S3N1 shown in Figure 3～S3N3).
Need to prove, Fig. 2, shown in Figure 3 and above-mentioned relevant introduction are the design of one-way flow by described two layers of transparent transmission equipment 220, handle if the described two layers of transparent transmission equipment 220 of all wishing to flow through toward regurgitation volume are carried out corresponding service, only need oppositely dispose again described PBR and described Static ARP and get final product.
