METHOD FOR APPLYING DYNAMIC UPDATES OF FORWARDING AND QOS RULES ON FLOW BASED NETWORK DEVICES

摘要

PURPOSE: A method for providing forwarding information and QoS(Quality of Service) information in a flow-based network device is provided to dynamically apply forwarding information and QoS processing information to a corresponding flow. CONSTITUTION: If an inputted packet is not a primary packet(S110), a forwarding engine unit obtains the serial information for the packet. The forwarding engine unit first and second information from a flow table within a network device based on the state information for a specific flow(S160). The forwarding engine unit judges based on a rout ID of the serial information whether or not the first and second information are updated(S170). If is judged whether or not the first and second information are updated, the forwarding engine unit updates the flow table(S190).
