Abstract
Method and computing devices for enforcing packet order based on packet marking. Upon occurrence of a link failure, a first device reallocates traffic initially forwarded through the failed link to an alternative link and marks the reallocated traffic with a first flag. Upon recovery of the failed link, the reallocated traffic is forwarded again through the recovered link and marked with a second flag different from the first flag. A second device calculates a reference inter-packet time for received traffic marked with the first flag. For received traffic marked with the second flag, the second device calculates a current inter-packet time. The current inter-packet time is compared with the reference inter-packet time, to determine if the traffic marked with the second flag shall be forwarded immediately or if the forwarding shall be delayed.
