IN-NETWORK MESSAGE PROCESSING METHOD, IN-NETWORK MESSAGE FORWARDING EQUIPMENT AND IN-NETWORK MESSAGE PROCESSING SYSTEM

摘要

The present invention discloses a method for processing a packet in a network, a forwarding device, and a packet processing system. The method includes: separately creating, by a forwarding device, a corresponding virtual device on the forwarding device for each controller according to an instruction of a resource manager; creating a flow table in the corresponding virtual device according to a flow table creation message from the controller; storing a correspondence between a first identifier of a to-be-created flow table that is carried in the flow table creation message and a second identifier of the flow table that is created on the forwarding device according to the flow table creation message; receiving a flow entry creation message from the controller, where the flow entry creation message carries a to-be-created flow entry and the first identifier of the flow table that is to store the flow entry; obtaining, according to the correspondence, the second identifier corresponding to the first identifier, and storing the flow entry in the flow table corresponding to the obtained second identifier; and receiving a data packet, and processing the data packet according to the flow entry in the flow table corresponding to the second identifier. By means of embodiments of the present invention, network efficiency can be improved.
