Abstract
A method and system is provided for re-routing a flow of packets in a packet-switched network at a rerouting time. In one embodiment, the method comprises accepting packets in a switch, routing the flow of the packets to a first destination via the switch according to a switch flow rule, receiving an updated switch flow rule from a controller before the rerouting time, the updated switch flow rule defining the rerouted flow of packets, and rerouting the flow of packets according to the updated switch flow rule at a rerouting time indicated by a packet of the accepted packets.
