Method, apparatus and system for establishing optical bypass

A method for establishing an optical bypass, comprising:

• receiving, by an optical transmission controller, an optical bypass establishment request sent by a routing controller;
• allocating, by the optical transmission controller, an optical bypass based on the optical bypass establishment request;
• and
• setting, by the optical transmission controller, a first stream forward entry corresponding to the optical bypass for each optical transmission device in the optical bypass and sending the set first stream forward entry to the corresponding optical transmission device;
• and sending, by the optical transmission controller, an establishment success notification to the routing controller.

An optical transmission controller, comprising:

• a receiving module, configured to receive an optical bypass establishment request sent by a routing controller;
• an allocation module, configured to allocate an optical bypass based on the optical bypass establishment request;
• and
• a sending module, configured to set a first stream forward entry corresponding to the optical bypass for each optical transmission device in the optical bypass, and send the set first stream forward entry to a corresponding optical transmission device;
• and send an establishment success notification to the routing controller.

A system for establishing an optical bypass, comprising a routing controller, an optical transmission controller, a routing device and an optical transmission device, wherein

• the routing controller is configured to:
• send an optical bypass establishment request to the optical transmission controller, wherein the optical bypass establishment request carries information about an ingress node, an egress node and a required bandwidth;
• and
• in response to receiving an establishment success notification sent by the optical transmission controller, set a second stream forward entry corresponding to the optical bypass for the ingress node and the egress node, and send the set second stream forward entry to the ingress node and the egress node;
• and
• the optical transmission controller is configured to:
• receive the optical bypass establishment request sent by the routing controller;
• allocate the optical bypass based on the optical bypass establishment request;
• set a first stream forward entry corresponding to the optical bypass for each optical transmission device in the optical bypass, and send the set first stream forward entry to the corresponding optical transmission device;
• and
• send the establishment success notification to the routing controller.
