- Minutes of the Remote LAN Monitoring Working Group (RMONMIB)
-
-
- Monday
-
- The RMONMIB Working Group met twice at the Toronto IETF. Due to some
- scheduling conflicts for the formal presentations, the initial meeting
- focused on general issues for the next version of RMON and a status
- review of the current RMON draft.
-
- The charter was discussed. No changes were suggested, but the group did
- note the short period in which a new RMON must be completed. It was
- recommended that the working group hold interim meetings focused on
- various issues to be considered for a new RMON. Also formal proposals
- would be solicited for new features. Possible dates for an interim
- meeting would be forthcoming.
-
- The Monday meeting concluded with a discussion of the current RMON draft
- (17 June 1994). A Last Call was held within the working group and the
- draft was forwarded to the area director with a recommendation that the
- draft become a Draft Standard. Members of the Network Management Area
- Directorate have reviewed the draft and have suggested changes (textual
- only). As a result of the July interoperability testing, some issues
- were raised. For those issues that do actually pertain to RMON, textual
- changes will be made at the direction of the Network Management Area
- Directorate.

- Tuesday
-
- The Tuesday RMON session was devoted to presentations on various topics
- for the new RMON. Copies of these presentations are available via
- anonymous FTP from jarthur.cs.hmc.edu in the pub/rmon/toronto directory.
-
- Nevil Brownlee presented an overview of the accounting MIB and its
- architecture. He has implemented the MIB on a number of platforms
- (freely available implementation). Rules are used to describe the
- traffic patterns of interest. Nevil has some data on performance issues
- related to agent processing.
-
- Sonia Panchen made a presentation of Statistical Sampling for network
- traffic monitoring. Hewlett-Packard has released a product, EASE, that
- demonstrates a practical implementation of sampling for traffic
- monitoring.
-
- Venkat Rangan presented MIB structures to include network address
- information in the RMON structure and to handle variable length headers
- in the filter area. These modifications were part of the RMON
- extensions implemented by Hewlett-Packard.
-
- Timon Sloane and Karl Auerbach presented possible MIB extensions to
- allow for a packet generation capability in RMON and possible changes to
- the existing filter mechanism. Karl also described his stack machine
- for filter processing.
-
- Steve Waldbusser presented his list of pressing issues for a new RMON:
- new filter language, network layer host and matrix, protocol type
- distribution, trap destination, serial line configuration, issues of
- static versus extensible and repeater/bridge ports. Discussion
- indicated little interest in serial line configuration, but the other
- issues remain of interest to the group.
-
-
- o Filter language:
- - needs to handle variable length fields
- - simple to implement
- - hopefully already defined
- - efficient encoding
-
- o Berkeley packet filter:
- - three to four generations of refinement
- - implementations available
- - space-efficient encoding
