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. -Skip On Sat, 5 Aug 2000, Bill Sommerfeld wrote: > > I would add a third reason for heartbeats/keepalives.
