This is a reminder, sent out once a month, about your
lists.bell-labs.com mailing list memberships.  It includes your
subscription info and how to use it to change it or unsubscribe from a
list.

You can visit the URLs to change your membership status or
configuration, including unsubscribing, setting digest-style delivery
or disabling delivery altogether (e.g., for a vacation), and so on.

In addition to the URL interfaces, you can also use email to make such
changes.  For more info, send a message to the '-request' address of
the list (for example, iptel-request@lists.bell-labs.com) containing
just the word 'help' in the message body, and an email message will be
sent to you with instructions.

If you have questions, problems, comments, etc, send them to
mailman-owner@lists.bell-labs.com.  Thanks!

Special Session: ABR to the Internet
====================================

THE 5TH WORLD MULTICONFERENCE ON SYSTEMICS, CYBERNETICS AND INFORMATICS
SCI'2001
July, 22-25, 2001

Orlando, Florida(USA)
Sheraton World

http://www.iiis.org/sci/


THE "ABR TO THE INTERNET" SESSION:
ATM's "Available Bit Rate" (ABR) service provides a dramatically reduced
cell loss ratio by means of a signaling mechanism called "Explicit Rate
Feedback"; information from the network is provided to end nodes in order to
facilitate adaptation.
On the contrary, adaptive Internet applications rely on mechanisms that
probe the network in order to avoid congestions; packet loss must be
experienced before it can be avoided on a long term basis. Developers of
commercial applications seem to avoid adaptation because they don't see
enough QoS benefit.


SCOPE:
As a first step, we have seen ECN enhance adaptation on the Internet.
We are looking for papers that represent the next step.

Topics of interest include, but are not limited to, the following questions:
* What data should be provided to end nodes?
* Which QoS could be achieved?
* Where should the signaling take place? (end2end, edge2edge, core, ...)
* How do we deal with path changes?
* Can the signaling be incorporated with DiffServ, MPLS, ...?
* What about fairness issues and TCP-friendliness?


SUBMISSION OF PAPERS:
Prospective authors are invited to submit an extended abstract (about 1.5 to
2 pages) to Michael Welzl (michael@tk.uni-linz.ac.at) in postscript, PDF or
Word 97 format.
English is the official language of SCI 2001, thus all papers must be
submitted and presented in English.


EVALUATION PROCESS:
Papers will be evaluated for originality, significance, clarity, and
soundness.  Each paper will be refereed by several researchers in the
topical area.


THE CONFERENCE:
SCI 2001 is an international forum for scientists and engineers, researchers
and consultants, theoreticians and practitioners in the fields of Systemics,
Cybernetics and Informatics. It is a forum for focused disciplinary
research, as well as for multi, inter and transdiciplinary studies and
projects. One of its aims is to relate disciplines fostering analogical
thinking and, hence, producing input to the logical thinking.

Invited Sessions with high quality papers might be selected for multiple
author book publications. Two books are being published now as result of
good invited sessions.


IMPORTANT DATES:
18. 01.  Submission of extended abstracts (1.5 - 2 pages)
16. 02.  Notification of acceptance
13. 04.  full papers due

All accepted papers are expected to be presented at the conference.


OTHER INFORMATION:
It is planned to hold a BOF session on "ABR to the Internet" at a future
IETF meeting; authors are invited to join this collaborative effort which
may eventually be a realization of this session's topic. Further information
on the BOF can be found at http://www.tk.uni-linz.ac.at/~michael/ptp

Hi all,

Should every script submitted to a CPL server contain a doctype
declaration  and if yes, should this exactly be:  <!DOCTYPE cpl PUBLIC
"-//IETF//DTD RFCxxxx CPL 1.0//EN" "cpl.dtd"> ?

Thanks in advance
David

In XML the document type declaration is optional and although all the
examples in the internet draft contain an external reference they could
just as easily contain the full DTD !! Our implementation doesn't require
the document declaration as it uses an internal representation of the DTD
anyway and won't accept generic XML (it's meaningless out of context).

Well, I'd prefer it be there in any case, since it lends context to CPL
scripts. 

ALso, note that the format of the declaration would not be RFCxxxx; this
will be replaced by the ultimate RFC number assigned to CPL.

Folks,

A reminder that the working group last call for TRIP:

http://www.ietf.org/internet-drafts/draft-ietf-iptel-trip-04.txt

has expired. We received a few comments (IANA considerations needs more
detail, and a change in the naming of the hexadecimal routing numbers to
exclude F), and these will be incorporated into the next draft, due out in
about a week. I wanted to give people the opportunity to use that week to
get their comments in. So, please do so NOW.

Thanks,
Jonathan R.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Telephony Working Group of the IETF.

	Title		: Authentication Attribute for TRIP
	Author(s)	: J. Rosenberg, H. Salama
	Filename	: draft-ietf-iptel-trip-authen-00.txt
	Pages		: 5
	Date		: 15-Jan-01
	
This document defines a new TRIP attribute, the Authentication
attribute. The Authentication attribute carries signatures for one,
or more, of the attributes carried in the same UPDATE message. The
purpose of these signatures is to guarantee the integrity of the data
being advertised across multiple TRIP hops.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-iptel-trip-authen-00.txt

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-iptel-trip-authen-00.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-iptel-trip-authen-00.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

A quick note. This draft is  just a place holder for the authentication attribute
which was removed from the TRIP protocol draft before the San Diego meeting.

Sorry this is so late

The text for lookup and the DTD conflict, the DTD says

<!ELEMENT lookup ( success,notfound?,failure? ) >

yet the text implies that success should be optional too and its absence
result in the default action being taken.

Sorry again for sending yet another late observation.

The algorithm in appendix A fails to account for durations that are
"negative" i.e. start with the character '-'. The simplest solution would
be to disallow them, however, the changes to the algorithm are simple
(!?). 

Step 1b If duration is negative, make it positive and subtract it from
dtstart.

I think this will work
