If the application is running CTP, does the base node not automatically 
identify a unique packet?? As TEP-123 says that together origin, seqno and 
collect_id fields denote a unique *origin packet* THEN why do we need to put 
such a unique number in the payload??


Cheers,

Typically this is done by putting such unique number (eg. counter
value) in your payload.
