All,

I have update to the begin/end fragmentation protocol for Ethernet [1].  This update fixes an error in the sequence number reset algorithm.  There was a case when one node rebooted during the synchronization process and that reboot went undetected.  The draft also now has a state diagram for the reset mechanism.  Python code in github [2] implements the reset algorithm in simulation and may be referred to for an example of the reset algorithm.

This reset mechanism is not yet implemented in the CCNx code release.
