FEDERATION OF CONTROLLERS MANAGEMENT USING PACKET CONTEXT

摘要

In a network control system, a method for managing traffic flow in a distributed controller environment includes stamping a packet to be forwarded between data forwarding units with flow control information based on an action set associated with a flow entry pushed by a logical controller. The packet is stamped by one or more of the data forwarding units. The flow control information is used to forward the packet between data forwarding units, thereby defining a datapath packet flow.
