PACKET MIS-ORDERING PREVENTION IN SOURCE ROUTING HITLESS REROUTE USING INTER-PACKET DELAY AND PRECOMPENSATION

摘要

A method implemented by a network element (NE), comprising forwarding one or more initial packets in a packet flow from a source to a destination along an initial route having an initial route packet delay, obtaining an updated route having an updated route packet delay less than the initial route packet delay, and delaying transmission of a subsequent packet over the updated route by an amount of time determined in accordance with the initial route packet delay, the updated route packet delay and an inter-packet delay associated with the packet flow.
