When employing adaptation layer fragmentation in 6LoWPAN, it may be beneficial for a forwarder not to have to reassemble each packet in its entirety before forwarding it. This has always been possible with the original fragmentation design of RFC4944. This method reduces the latency and increases end-to-end reliability in route-over forwarding. It is the companion to the virtual Reassembly Buffer which is a pure implementation technique.
