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.
