Byte counting in draft-winter-radext-fancyaccounting-00

[Peter Deacon <peterd@iea-software.com>]

There is sometimes confusion (For me anyway) regarding what counters 
actually count.  Traditionally Input/Output octets are protocol agnostic 
and just count low layer bits shuffled between interfaces.

Lets say we run IPv6 over PPP or Ethernet do the byte counts apply only to 
the higher layer IP frames and not a lower layer ethernet or PPP frame?

Alternately if there was a traffic class for even higher layer messages such 
as HTTP..does it count the HTTP layer only or the IP header and possibly 
ethernet/PPP header?

I don't really have an opinion on the behavior only that it would be best 
if all implementations stand a good chance of counting the same way.

regards,
Peter
