Problems solved by technology

When business management is based on the actual physical topology structure, once the management scale of the controller increases or the topology becomes complex, the difficulty of business deployment increases and the speed of business failure recovery is slow, so the performance of the controller is weak

Embodiment Construction

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0039] The present invention provides a method for calculating a label forwarding path, refer to figure 1 , in an embodiment, the calculation method of the label forwarding path includes:

[0040] Step S100, receiving a path calculation request sent by the path calculation client PCC;

[0041] The embodiments of the present invention are applicable to controller service processing in a software defined network (Software Defined Network, SDN). When service processing is required, the head node in the specific service, as the Path Computation Client PCC (Path Computation Client), receives the service processing request sent by the SDN controller, and sends the request to the Path Computation Element PCE (Path Computation Element) in the SDN controller after receiving the service processing request sent by the SDN...

Abstract

The invention discloses a method for calculating a label forwarding path. The method for calculating a label forwarding path includes receiving a path calculation request sent by a path calculation client PCC; when the received path calculation request contains node information dedicated to service processing At the time, the service type in the node information is obtained, and according to the service type, the logical topology used by the service type is obtained from the mapping relationship table between the service type and the logical topology to calculate the label forwarding path. The invention also discloses a label forwarding path computing system. The invention reduces the difficulty of service deployment, improves the speed of service failure recovery, and thus improves the performance of the controller.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to a method and system for calculating a forwarding path of a label. Background technique [0002] In today's rapidly changing Internet environment, the flexibility and agility of the network are critical. When business management is performed based on the actual physical topology, once the management scale of the controller increases or the topology becomes complex, the difficulty of business deployment increases and the recovery speed of business failures is slow, so the performance of the controller is weak. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a method and system for calculating a label forwarding path, which aims to reduce the difficulty of service deployment, improve the speed of service failure recovery, and thus improve the performance of the controller. [0004] To achieve the above purpose, ...
