摘要
A method is performed by a network device acting as a switch in a Software Defined Networking (SDN) network, where the switch is coupled to a controller in the SDN network. The method implements variable buffer timeout output actions. The method includes generating a flow entry that includes a packet matching criteria and an output action that specifies a buffer timeout value, receiving a packet for forwarding, determining whether the packet matches the packet matching criteria of the flow entry, and storing the packet in a buffer of the switch in response to determining that the packet matches the packet matching criteria of the flow entry, the buffer to temporarily store the packet while the controller determines processing for the packet. The method further includes associating the buffered packet with the buffer timeout value specified in the flow entry and transmitting a portion of the packet to the controller.
