Problems solved by technology

However, this method not only requires the intervention of planners, but also requires other configurations. On the one hand, this increases the labor cost, and on the other hand, the efficiency of path separation is not high, which reduces the transmission performance of the system.

Embodiment 1

[0022] Embodiment 1: Embodiment 1 of the present invention provides a method for path separation, such as figure 2 Shown is a schematic flow diagram of the provided method comprising:

[0023] 21: The head node of the current tunnel receives the path information sent by the head node of the associated tunnel.

[0024] There are at least two associated tunnels between the source node and the destination node. For example, when there are two active and standby tunnels between the source node and the target node, the active tunnel and the standby tunnel can be referred to as associated tunnels. Likewise, when there are more than two tunnels between the source node and the target node, the two or more tunnels may be called associated tunnels.

[0025] Select one of the associated tunnels as the current tunnel. When it is necessary to separate the path of the current tunnel from other associated tunnels, the head node of the current tunnel can receive the path sent by the head no...

Embodiment 2

[0042] Embodiment 2: This embodiment 2 is described with specific examples, or with the appended image 3 For example, in the figure, for the convenience of description, the current tunnel is set as tunnel A, and the associated tunnel is set as tunnel B:

[0043] When tunnel A and tunnel B need to separate paths, the head node 1 of tunnel B will send the path information of tunnel B to head node 2; if tunnel B does not establish a path at this time, the carried path information will be empty. In the specific implementation process, the path information can be carried in the private protocol message, and the information sent through the private protocol message also includes: the address of the router where the A tunnel is located, the name of the A tunnel, the address of the router where the B tunnel is located, and the name of the B tunnel Wait.

[0044] Head node 2 receives the path information of tunnel B sent by head node 1. If tunnel A has not established a path, it can ...

Embodiment 3

[0051] Embodiment 3: In this embodiment 3, the scene when the route is changed is used for illustration, or the attached image 3 For example, in the figure, for the convenience of description, the current tunnel is set as tunnel A, and the associated tunnel is set as tunnel B:

[0052] When tunnel A needs to change the path information due to re-optimization or rerouting, the head node 2 uses the path information of tunnel B as an excluded path for path calculation. After the path calculation is successful, tunnel A is established according to the new path information, so that When changing, the path separation of tunnel A and tunnel B can also be realized.

[0053] In addition, after the calculated path is used as the path of the tunnel A, the new path information of the tunnel A may also be sent to the head node 1 of the tunnel B. In the specific implementation process, it can be sent through a private protocol message. The specific information that the private protocol me...

Abstract

The embodiment of the invention provides a method, a device and a system for splitting a path. The method comprises the following steps: firstly, a first node of the current tunnel receiving path information sent by a first node of a tunnel correlated with the current tunnel; and then using the path of the correlated tunnel as an excluded path to calculate the path, and using the calculated path as the path of the current tunnel. Therefore, the method, the device and the system can achieve path splitting between the current tunnel and the correlated tunnel and save labor cost because the process needs no intervention of labor, and improve splitting efficiency of the path, so as to promote transmission performance of the system.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method, device and system for path separation. Background technique [0002] Currently, in the process of data transmission, the security of data transmission is generally protected by means of active and standby tunnels. Such as figure 1 Shown is the transmission diagram of the non-head node association protection of the traffic engineering TE tunnel. In the figure: the source node S sends data to two independent provider edge equipment (PE), namely the head node 1 and the head node 2 above; then the first node 1 and the first node 2 respectively establish independent TE tunnels to reach the same target node. [0003] In order to obtain more effective protection between the primary and secondary tunnels of the first node 1 and the first node 2, and prevent simultaneous failure of the primary and secondary tunnels, it is necessary to separate the paths of the prim...
