Abstract
A method and apparatus for maintaining packet order integrity in a switching engine wherein inbound packets are forwarded to different ones of parallel processing elements for switching. Order preservation for packets relating to the same conversation is guaranteed by checking for each inbound packet whether a previous packet from the same source is pending at a processing element and, if the check reveals that such a packet is pending, forwarding the inbound packet to the same processing element as the previous packet.
