Embodiment 1
[0044] An embodiment of the present invention provides a method for establishing a path for cross-domain service intercommunication, which is applied to the first controller, such as figure 1 shown, including:
[0045] Step 101: Establish a forwarding path of the second-layer forwarding device; wherein, the starting node of the forwarding path of the second-layer forwarding device is the second-layer forwarding device, and the destination node is a border node of the third-layer forwarding device;
[0046] Step 102: Establish a forwarding path of the third-layer forwarding device; wherein, the forwarding path of the third-layer forwarding device represents a path between the third-layer forwarding devices located at the boundary;
[0047] Step 103: Concatenate the forwarding path of the second-layer forwarding device and the forwarding path of the third-layer forwarding device to obtain a spliced forwarding path.
[0048] Further, in this embodiment, after step 103 is complet...
example 1
[0059] Among them, the dynamic establishment of the forwarding path method, the specific process, such as Figure 4 shown, including:
[0060] Step 401: Establishing an L2 forwarding path;
[0061] Specifically, the user equipment 1 initiates an address resolution protocol (ARP, Address Resolution Protocol) request for the L3 forwarding equipment 1 via the L2 forwarding equipment; after the L2 forwarding equipment 1 receives the ARP request, it analyzes the main control board and uploads it to the Domain Controller1; Domain Controller1 checks the destination IP address of the ARP request, and indexes it to L3 forwarding device 1; and, Domain Controller1 establishes an L2 forwarding path; wherein, the starting node of the L2 forwarding path is L2 forwarding device 1, and the destination node is L3 Forwarding device 1.
[0062] Step 402: establishing an L3 forwarding path;
[0063] Specifically, the Super Controller automatically selects the L3 boundary point (the device conn...
example 2
[0073] Example 2: statically establish forwarding path, such as Figure 6 shown, including:
[0074] Step 601: Establishing an L2 forwarding path: manually input the starting point and end point in the APP to establish the L2 forwarding path, select the starting node as the L2 forwarding device 1 and the destination node as the L3 forwarding device 1 on the APP. Send it to the Super Controller through the interface (such as Restconf, Restful, etc.), and the SuperController sends Domain Controller1, Domain Controller1, and Super Controller through the interface (such as Restconf, Restful, etc.). An L2 forwarding path is established on the device.
[0075] Step 602: Establish L3 forwarding path: Manually input L3 boundary points in APP to establish L3 forwarding path, for example, select L3 boundary points as L3 forwarding device 1, L3 forwarding device 2, and L3 forwarding device 6 on APP. Send it to the Super Controller through the interface (such as Restconf, Restful, etc.)...
