     1== Prior version of protocol ==

     3=== Drawbacks ===
     4
     5* Somewhat limited flow control, using ACK withholding at chunk granularity. Problematic under simultaneous transfers of multiple large chunks.
     6* No congestion control. In particular, if receiving capacity is temporarily affected, the sender didn't back off, but also paid heavy penalties due to lost control packets - incurred timeout events.
     7* Did not support partial chunk transfers. If sender knows that receiver cannot handle chunks at the size they were received, sending smaller chopped up chunks should be supported.
     8* Did not support reboots/memory losses. Numbering used to uniquely identify chunks were reset after restarts with no way to tell the other node that it was reset.
