Operational Requirements Area Report


Directors:

o  Scott Bradner <sob@newdev.harvard.edu>
o  Mike O'Dell <mo@uunet.uu.net>

Four Operational Requirements Working Groups met during the Dallas 
IETF meeting and there were five BOF sessions held.


BMWG AM Session, December 5, 1995

The BMWG met Tuesday morning to work on the device benchmarking 
agenda.  Jim McQuaid led the session.  The group discussed the status of 
the current I-D on network element benchmarking.  The recent changes 
and several small open issues were discussed and resolved.  The group 
feeling is to complete the current I-D as an informational RFC and to let 
new methodology documents add methods or definitions as needed in 
the future, rather than revise and supersede this document constantly.  
Initial discussions were held on Ethernet switch testing methods and 
the benchmarking of call setup in SVC networks.


BMWG PM Session, Dec 5, 1995

The BMWG met late Tuesday afternoon to work on the IPPM agenda.  
Guy Almes led the session.  After a brief review of history and status, 
discussion focused on four areas:

o  measures of delay,
o  measures of flow capacity,
o  (very brief) measures of availability, and,
o  the use of probe/transponder machines.

The formal session concluded with a talk by Steve Corbato.


CIDRD Working Group

The CIDRD Working Group met at the Dallas on Wednesday, 
December 6.  Tony Li gave a summary of the IPv4 address space 
allocations, with extrapolations giving an Ipv4 address space lifetime 
of 2018 +/- 8 years.  Fred Solensky presented a logistical analysis of the 
usage of the 128/2 and 192/3 address space projecting that 128/2 usage 
will stabilize at 62% of the total and that 192/3 usage will stabilize at 
90% by 2006.  Questions were raised whether this sort of projection is 
meaningful.  Bill Manning reported that 13% of the 0/1 space has been 
reclaimed during the past six months.  Erik-Jan reported on the size of 
the global routing table, which has grown approximately 10% in the 
past four months.  The routing table represents over 822,000,000 
potential addresses of which approximately 8,000,000 are believed to 
be active.  This represents a utilization efficiency of less than 1%.  The 
status of a number of CIDRD documents was considered and debated: 
Appeal to Return Unused Address Space (submit as BCP), RFC1597bis 
(final revisions, submit as BCP), Address Ownership (revise, further 
review), Class A Subnet Deployment Considerations (submit as 
Informational), Net 39 Experiment Report (revise, review, submit as 
Informational), CNAME Extensions to IN-ADDR (rehome to DNSIND 
Working Group).  Much discussion of Non-Local Aggregation occurred, 
Internet-Draft to be crafted.  Yakov Rekhter presented on the subject of 
Charging for Routing Advertsements.  Much discussion followed the 
presentation.


PIER BOF

The PIER BOF was held in two sessions.  The first covered the draft 
charter, which was updated to reflect a broader scope of working group 
interaction with other working groups and a clarification on the focus 
on IPv4.  A review of a series of documents that had already been 
discussed was concluded.  It was noted that most of the documents 
reflected cookbook approaches to renumbering small sites.  A wide 
ranging discussion on renumbering ensued Participants dicussed how it 
applies to Routing & Infrastructure, Firewalls, Multihomed sites, 
Servers, API's, and Tools.  A number of participants indicated that they 
were either currently involved in a renumbering project or were going to 
start one very soon.  There was agreement that a working group (or two) 
ought to be formed to address some of these issues.

The second session was used to generate milestones.  Six classes of 
documents were identified:

o  How to renumber small sites;
o  A Goal statement;
o  Where IP addresses are used in applications;
o  Tool catalog;
o  Case studies; and,
o  How renumbering affects my network presence.

Volunteers were "persuaded" to tackle at least one item for each group.  
It is expected that a majority of the work will be completed by Summer 
1996.



RADIUS BOF

The RADIUS BOF had 102 attendees.  Suggestions were made to have a 
NAS-Port-Type instead of the recently proposed NAS-Port-Id.  This 
will be followed up on the mailing list.  A few clarifications were 
suggested for Draft 01 of RADIUS and RADIUS accounting.  The 
attendees were very supportive of the idea of attempting to move the 
RADIUS draft to Proposed Standard in January, and if that wasn't 
possible in a relative timeframe, then to issue it as an Informational 
RFC in January.  Then, a continuing effort would be made on getting it 
placed on a Standards Track.  Members were very supportive of the 
idea of amending the charter to start work on a separate Internet-Draft 
concerning RADIUS extensions, as long as that wouldn't imperil the 
standards-track status of the current RADIUS draft.  The Working 
Group charter will be revised accordingly.  Interest was also expressed 
in holding a RADIUS Bake-Off in the Spring.


RPS Working Group

A mechanism to support Destination Preference Attribute was 
presented, along with the pros and cons of using AS-Macros or AS-
Expressions in specifying AS Peerings in policy terms.  Curtis 
Villamizar presented what needs to be specified to handle aggregation 
and different alternatives to achieve it.  There was no consensus at the 
meeting, but consensus should be reached on the mailing list.

There was a debate on the mailing list whether the rpsl as path 
regular expressions should be character (like Cisco) or integer (like 
gated) based. The rpsl syntax was presented and compared to both Cisco 
and gated syntaxes.  Several ISP representatives who actually use 
Cisco routers suggested to stick with integer based expressions.  There 
was a unanimous agreement.

Deborah Estrin's work on multi-cast policies was presented.  Tony Bates 
suggested that it be published as an informational RFC.  Extensions needed to 
support and take full advantage of SDRP were suggested.  David 
Kessens' work on Real Time Database mirroring was presented.  Jerry 
Scharf presented his intentions to implement a database format 
independent transport mechanism.

RTFM BOF

Fifty seven people attended the BOF.  Four presenters covered the 
following topics: the need for flow measurement from ISP and large 
customer perspectives; and, existing implementations of the Meter MIB 
experiences with the existing measurement tools.  Consensus was that a 
standard way of collecting flow data is highly desirable and that a 
traffic measurement working group be formed to review existing 
proposals and produce a standards track document set.  A discussion list 
will be established: <rtfm@auckland.ac.nz>.  In addition, 
draft charter was prepared.

RWhois WG

Scott Williamson presented the working group with a summary of the 
current status of the implementation.  The working group then 
discussed what is required in making RWhois operational based on the 
current experiences and to develop planned steps to make it robust.  The 
Working Group then discussed changes to the initial version of the 
protocol and ways of entering authentication within rwhois for updates 
and new records.  Then followed a discussion about reducing flat spaces 
using DNS.  The Working Group concluded with a call for volunteers to 
help develop RWhois.

STDGUIDE BOF

The draft of the guide was presented at the meeting and discussed.  A 
new version incorporating input from the meeting will be prepared by 
the authors and sent out on the mailing list.
