Embodiment 1

[0023] Referring to Fig. 2, the embodiment of the present invention discloses a method for improving the service recovery performance of a multi-layer network, which specifically includes the following steps:

[0024] Step 101: When a fault occurs in any part of the optical fiber, the corresponding service layer tunnel head node and client layer LSP head node will receive a fault notification, and the fault notification includes the node ID and port ID where the alarm occurred. At this time, the LSP at the client layer does not take any action, and waits for the head node of the tunnel at the service layer to first locate the location of the fault.

[0025] Step 102: The head node of the service layer tunnel that has received the fault notification traverses the path resource information of all service layer tunnels related to the node and port where the alarm occurs.

[0026] Step 103: According to the path resource information traversed by the first node of the service layer...

Embodiment 2

[0042] Referring to FIG. 4 , the embodiment of the present invention also provides a device for improving service recovery performance of a multi-layer network, including a judging module 201 and a fault recovery module 202 .

[0043] Judging module 201 is used for judging whether the end node of the service layer tunnel related to the fault fails after receiving the fault notification, and sends the judgment result to fault recovery module 202;

[0044] The failure recovery module 202 is used to receive the judgment result sent by the judgment module, if the end node of the service layer tunnel fails, then restore the client layer tunnel; if the end node of the service layer tunnel does not fail, then perform the service layer tunnel recovery.

[0045] The judging module 201 may specifically include an upstream node judging unit 201a, a waiting unit 201c, and a terminal node reachability judging unit 201b;

[0046] The upstream node judging unit 201a is used to judge whether...

Embodiment 3

[0052] The reason why the waiting unit in the fault judging module 201 waits for the routing of the fault status to be diffused is to confirm that the node fails only when all ports of the node have alarms. The waiting unit may also not be used, and as long as there is a port alarm, the step of judging whether the end node is reachable is directly carried out.

[0053] Referring to Fig. 5, the judging module 201 may specifically include an upstream node judging unit 201a and a terminal node reachability judging unit 201b.

[0054] The upstream node judging unit 201a is used to judge whether the port where the alarm occurs is the outgoing port of the upstream node of the end node of the tunnel, if yes, then send the judgment result to the end node reachability judging unit 202b, if not, then The end node of the service layer tunnel is not invalid.

[0055] The end node reachability judging unit 201b is configured to receive the judging result sent by the upstream node judging ...

Abstract

The invention discloses a method and device for improving the multiplayer network service recovery performance, belong to the network communication field, in order to overcome the defects of available technologies, such as the whole client service recovery time too long, can't meet with the requirements of network service, this method includes the following steps: after received the fault notification, determine whether the final node of service layer concerning with the fault is ineffective or not; if yes, then recover the tunnel of client layer; if no, then recover the tunnel of service layer. The device includes the decision module and fault recovery module. The invention may not only ensure the recovery efficiency of the whole network, but also ensure the optimum recovery performance of a single service under different conditions.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a device for improving the service recovery performance of a multi-layer network. Background technique [0002] With the development of network integration and network flattening, the boundaries between different types of networks are gradually blurred. A generalized multi-layer network under a unified control plane has become the goal pursued by people, and finally realizes flexibility and efficiency between different layers of networks. The hybrid scheduling of the network optimizes the management of network services and improves the survivability of the network. In the hybrid scheduling of multi-layer networks, the use of layered tunnel technology can effectively improve the efficiency of service scheduling, shield the impact of different layers of services, so that only the interfaces and policies between different layers of tunnels need to be paid attention ...
