Problems solved by technology

[0003] However, the current PTN service opening may involve multiple systems, involving the configuration between L2 and L3 routers, which will increase the coordination time of service intercommunication, and the complexity of multiple domain configurations will also greatly increase
However, the SPTN system has not yet considered the solution for the intercommunication between SPTN domain and routing domain equipment.
These shortcomings lead to the need for manual configuration when the current PTN or SPTN system communicates with the router network, which leads to complex configuration, requires strong professional knowledge, and leads to long activation time

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 Image 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 Super Controller sends Domain Controller1, Domain Controller1, and Super Controller through the interface (such as Restconf, Restful, etc.). After the APP interacts with the path information, it sends it to the An L2 forwarding path is established on the forwarding 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 i...

Abstract

The invention discloses a path establishment method and system for cross-domain service interconnection, and a controller. The method comprises the steps of: establishing a forwarding path of a second-layer forwarding device, wherein the start 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 a third-layer forwarding device; establishing a forwarding path of the third-layer forwarding device, wherein the forwarding path of the third-layer forwarding device characterizes a path between forwarding devices at the border on the third layer; splicing 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; and after receiving a BGP (Border Gateway Protocol) message, determining a corresponding routing table based on the BGP message and the spliced forwarding path, and sending the routing table to the third-layer forwarding device, so that at least two pieces of user equipment establish an interconnection path via the corresponding second-layer forwarding device and third-layer forwarding device.

Description

technical field [0001] The invention relates to routing control technology in the field of network management, in particular to a method for establishing a path for cross-domain service intercommunication, a controller and a system. Background technique [0002] Packet Transport Network (PTN, Packet Transport Network) inherits the concept of traditional transport network and meets the development requirements of IP. PTN realizes the "separation of control and forwarding" - making the path of the network knowable, manageable and controllable through planning. The architecture of the PTN network can be logically divided into three levels: the forwarding plane, the control plane, and the management plane. The forwarding plane is based on MPLS-TP technology, and the management plane is the current network management system. The control plane of PTN is disassembled into two parts: the first part, which is also the most important control function, including protocols such as path...
