Operational Requirements Area

Area Summary reported by Scott Bradner/Harvard and
Mike O'Dell/UUNET
Meetings of five Operational Requirements Area working groups and four
BOFs were held during the IETF meeting in Danvers, Massachusetts.
IP Provider Metrics BOF (IPPM)
The primary topic for the BOF was the formation of a working group,
although many of the areas where new technology might be needed were
introduced. It was the consensus of the attendees that the work is
important and belongs in a working group. It should focus on the
delivery and routing of datagrams (and not related services, such as NOC
characteristics). There is an apparent overlap with the BMWG Working
Group, but the common view was that the work would be stronger in a more
narrowly focused effort.
Some requirements for metrics and a wish list of useful metrics were
drafted. Some existing performance tools were briefly surveyed. Matt
presented a bulk transfer performance tool, ``treno,'' which he is
working on. Bill Manning lead an extensive discussion on metrics that
might be applied to routing.
Protocol Testing BOF (PROTTEST)
The session began with a discussion of goals; they included definitions
and methodology for testing of protocols, and guidelines for testability
of specifications and protocols. The discussion soon focused on
testability, with the idea of producing a set of informational
guidelines for RFC authors to assist in creating testable (and
implementable) specifications. It was decided to proceed by chartering
a working group, with the goal of producing an Informational RFC. Art
Mellor volunteered to be chair, and Peter Desnoyers to be document
editor. A charter will be drafted and discussed on the mailing list,
stdguide@midnight.com.
Remote Authentication Dial-In User Service BOF (RADIUS)
The RADIUS BOF had 42 attendees. There was considerable interest in
forming a working group to 1) create a standards track RFC documenting
the RADIUS protocol, and 2) create an Experimental RFC documenting
RADIUS Accounting as it exists now. Carl Rigney has the action item to
send out the minutes, a charter proposal and a proposed schedule to the
RADIUS mailing list and Operations Area co-Directors by 17 April, and
has volunteered to edit both documents. Several people expressed
interest in exploring the position of working group chair and are
talking to Carl and Mike O'Dell, Operations Area co-Director.
Routing Policy System BOF (RPS)
Daniel Karrenberg presented RIPE-181 to form the motivation and the
background for the working group. Cengiz Alaettinoglu presented RPSL
technical details (proposed details). Daniel presented the proposed
distributed registry model. Cengiz and Daniel presented the available
tools that operate on policy data in the registries. Curtis Villamizar
presented his results from specifying AS690 policies and made various
suggestions. The attendees interacted a lot and made many suggestions.
A consensus was reached that the work should be done as an IETF effort
in a working group.
CIDR Deployment Working Group (CIDRD)
Presentations on IPv4 address space usage and routing table size were
made. The latest projection on address space utilization gives 2018 +/-
8 years. The routing table size is approximately 25,000 routes, up
significantly from a year ago, but still showing dramatic reductions
from the old exponential growth curve.
An experiment will be run to see if the routing system is working with
subnets of class A address space. This will allow us to make use of the
reserved class A space, which is a substantial portion of the remaining
address space.
A talk on ``address ownership'' was given. Address ownership is
incompatible with hierarchical routing. A version of this talk will be
published as an RFC.
The working group agreed that RFCs 1597 and 1627 should be revised,
combined, and issued as a Proposed Standard.
The working group is also going to start a document to describe possible
filtering of very long prefixes to prevent insane exceptions from being
entered into backbone routing.
Guidelines and Recommendations for Security Incident Processing Working
Group (GRIP)
The GRIP Working Group met twice during this IETF. During the two
meetings, the content of a framework template for security incident
response teams was agreed on. This template will be included as an
appendix in the document that is being created (Guidelines and
Recommendations for Security Incident Response Teams). The group then
used the template to define an outline for the document itself. After
settling on the outline, the material in the current draft was reviewed
and the group defined the content they wanted to see in each of the
sections of the document. All in all, the two meetings were very
productive and the group expects to have a new draft out by 1 May. The
group further plans to have a second draft out by 1 June with the goal
of issuing a Last Call by the next IETF. The group is planning to meet
at the Stockholm IETF.
Network Status Reports Working Group (NETSTAT)
Summary not submitted.
Operational Statistics Working Group (OPSTAT)
An update on the status of 1404 was given. The 1404 draft is currently
out as an Internet-Draft. Minor changes are required before sending it
to the RFC Editor as an Informational RFC. The client-server draft has
incorporated all the changes submitted on the mailing list. Minor
changes were discussed and consensus was reached on incorporating them.
Work is progressing on the SNMP User's guide very slowly but hopefully
will pick up soon.
N. Brownlee discussed traffic studies that had been done at his site and
the statistical analysis of said traffic. They discovered that the
traffic had a self-similar nature. Simulations were performed utilizing
distributions with finite mean and infinite variance, but more work
needs to be done to determine the characteristics of the traffic in more
detail.
RWhois Operational Development Working Group (RWHOIS)
A meeting of the RWhois Working Group was held on 5 April. The status
of the RWhois release was discussed with an anticipated delivery of 1.0
BETA1 the following week. The issues of integrating an authentication
mechanism for registration was discussed. It was recommended to look at
the work done in the CAT Working Group in the Security Area. The group
also discussed the requirements of an RWhois registration server
including the minimum attributes, distributed record locking, and
secondary server requirements.
