Re: Heartbeats Straw Poll




Check out draft-ietf-ipsra-reqmts-01.txt.  Section 2.4 has the following
statements:

2.4 Accounting

   Accounting is used here to refer to the collection and reporting of
   connection status information by the IRAS. For remote access, the
   following accounting information is useful:

     o connection start time
     o connection end time
     o incoming octets (with respect to the IRAS)
     o outgoing octets (with respect to the IRAS)

   Note that the requirement for a connection-end-time attribute implies
   the need for a connection keep-alive mechanism of some sort so that
   the IRAS can accurately determine this quantity in cases where the
   IRAC does not explicitly terminate the connection. Also note that the
   keep-alive mechanism in this case is always directed from the IRAC to the
   IRAS.
