- Minutes of the Internet Accounting Working Group (ACCT)
-
- Internet Accounting Background
-
- The Wednesday session reviewed the Internet Accounting Background
- document which had recently moved to the status of RFC (1272). The
- major changes to this document since the July IETF were in the areas of
- security requirements and counting strategy.
-
- The security concerns for internet accounting were discussed and
- fundamental requirements were found to be data integrity and data
- confidentiality. It was recommended that, to the extent possible, SNMP
- security services should be used to satisfy these requirements.
-
- The counting strategy discussion revolves around how packets (datagram
- fragments) should be counted: on entry to a network or upon successful
- delivery. Since there are good arguments for both methods (depending on
- the intended use of the accounting information), the capability for both
- should be included in and internet accounting system.
-
- Working group participants offered comments, criticisms and suggestions
- that will be incorporated into either a new version of the RFC or follow
- on documents. Two new items were suggested: (1) it should be mentioned
- that, in addition to the uses already listed, internet accounting may
- also be used to monitor the correct operation of the network (i.e. it
- may reveal problems/anomalies); (2) among the values that an internet
- accounting system could report for a flow might be a binary value
- indicating whether a flow was active or not in the measured time period.
-
- Internet Accounting Architecture
-
- On Thursday the Working Group discussed the latest draft of the Internet
- Accounting architecture. Although this document has existed for several
- months now and has undergone 3 or 4 extensive revisions, it still needs
- work, both in form and content. An intensive session was spent going
- over the document section be section and paragraph by paragraph to
- refine both form and content. In particular the Working Group worked on
-
-
- o Tightening up the statement of scope that this document will
- address.
-
- o More carefully and clearly defining the IA model (and its
- difference from the OSI accounting model) and the interactions of
- its components.

-
-
-
-
- Numerous detailed (but important) changes were suggested and will be
- incorporated into the next version of the architecture document. Among
- them:
-
-
- o An explanation that we intend to develop a draft MIB and accounting
- control function definition, but not a complete protocol
- specification for accounting.
-
- o A clear statment about which packet processing layer accounting is
- done at, namely the IP layer.
-
- o The addition of a security section to the architecture document
- (and the role to be played by SNMP security services).
-
- o Definition of ``subscriber'', ``flow start time'' and other loosely
- used terms.
-
-
- The Working Group intends to conduct a dialog over the changes and a
- review of this document over the Internet in the next couple of months
- with a view of advancing it to the status of Internet Draft by the next
- IETF conference.
-
- General
-
- The Working Group has decided to combine the metering services document
- (formerly intended to be separate) with the architecture document and to
- announce our intention to produce a draft MIB document (separately)
- before the Working Group's effort is done.
-
- It was agreed that it is time once again to check what progress if any
- the OSI effort on accounting is making.
