METHOD, APPARATUS AND SYSTEM FOR ESTABLISHING OPTICAL BYPASS

摘要

Provided are a method, an apparatus and a system for establishing an optical bypass. The method includes: a route controller sending an optical bypass establishment request carrying information about an ingress node, an egress node and a required bandwidth to an optical transmission controller; and setting a second flow forwarding entry corresponding to the optical bypass for the ingress node and the egress node and sending the set second flow forwarding entry to the ingress node and the egress node when receiving an establishment success notification sent by the optical transmission controller, the establishment success notification being used for indicating that the optical transmission controller has allocated the optical bypass according to the optical bypass establishment request, set a first flow forwarding entry corresponding the bypass for each optical transmission device in the optical bypass, and sent the set first flow forwarding entry to a corresponding optical transmission device.

1. A method for establishing an optical bypass, comprising:
sending, by a routing controller, an optical bypass establishment request to an optical transmission controller, wherein the optical bypass establishment request carries information about an ingress node, an egress node and a required bandwidth; and responsive to receiving an establishment success notification sent by the optical transmission controller, setting, by the routing controller, a second stream forward entry corresponding to the optical bypass for the ingress node and the egress node, and sending, by the routing controller, the set second stream forward entry to the ingress node and the egress node, wherein the establishment success notification indicates that the optical transmission controller has allocated 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 sent the set first stream forward entry to the corresponding optical transmission device.
