Cell Relay FAQ - Introduction

The Cell Relay FAQ is posted periodically in multiple parts as a Usenet
News FAQ under the title comp.dcom.cell-relay FAQ: ATM, SMDS, and related
technologies. This FAQ is also maintained as a collection of WEB pages
(http://cell-relay.indiana.edu/cell-relay/FAQ/ATM-FAQ/FAQ.html). The WEB
pages will generally be more current than the posted FAQ. In fact this FAQ
is maintained as WEB pages then posted as a traditional Usenet News FAQ
every few months.

This article is the third of eight articles which contain general
information and also answers to some Frequently Asked Questions (FAQ) which
are related to or have been seen in comp.dcom.cell-relay. This FAQ provides
information of general interest to both new and experienced readers. It is
posted to the Usenet comp.dcom.cell-relay, comp.answers, and news.answers
news groups every few months.

This FAQ reflects cell-relay traffic through August 1997.

If you have any additions, corrections, or suggestions for improvement to
this FAQ, please send them to carl@umd5.umd.edu.

I will accept suggestions for questions to be added to the FAQ, but please
be aware that I will be more receptive to questions that are accompanied by
answers. :-)

SUBJECT C1)

             What are some good getting started ATM references?

Generally it is impossible to pick up any communications related technical
journal, conference, or trade publication and not find something about ATM.
However here are a few suggestions.

For *beginning* reading there are all sorts of ATM primers on the web.
These freely available primers are the best place to start. Several
pointers can be found in subject C7 "ATM Tutorials" of this FAQ. You can
find others by doing a search on the WEB. Many communication vendors have
good tutorials on their WEB sites. For starters try:

http://www.cisco.com
http://www.trillium.com
http://www.3com.com

Another suggestion is to try the atmforum website and go through past
issues of "53 bytes", their newsletter.

There are several books recommend for *intermediate* reading. These are
good for an engineer's basic understanding of most issues. Others are
listed in subject C2 "General ATM References" of this FAQ.

"Asynchronous Transfer Mode", Martin De Prycker, Ellis Horwood, New York
1996, ISBN 0-13-178542-7.
     Very readable general description of the technology and optimization.
     This book is now in its third edition.

"ATM - solutions for enterprise internetworking", David Ginsburg,
Addison-Wesley, 1996, ISBN 0-201-87701-5.

"ISDN and Broadband ISDN with Frame Relay and ATM", William Stallings,
third edition, Prentice-Hall, 1995, ISBN 0-02-415513-6.
     Third edition of Stallings ISDN book which now contains coverage of
     ATM and frame relay. The book is intended to be both a professional
     reference and a textbook.

"Gigabit Networking", Craig Partridge, Addison-Wesley, Reading MA, 1993,
ISBN 0-201-56333-9.
     Very well written book. Craig is the Editor of "IEEE Network"
     magazine. Topics: fiber optics, cell networking, ATM, Gbps packet
     schemes, applications, host interface, higher protocols, bandwidth
     management and performance, distributed systems, etc.

For *advanced* reading I'd recommend you actually read the ATM
specifications as published by the ATM Forum, and the IETF RFC's that deal
with ATM: Traffic Management, UNI, MPOA, PNNI, etc. See subject C4 in the
FAQ for ways to obtain ATM Forum documents. See subject C9 in the FAQ for
ways to obtain IETF RFC's.

---------------------------------------------------------------------------
SUBJECT C2)

                           General ATM References

Quite a lot has been written about ATM in the 80's and 90's. Most of what
has been written before 1990 primarily deals with the application of ATM to
Broadband ISDN. That which is written from 1990 onward cover the explosion
of ATM development in the carrier environment as well as in enterprise
networks, LANs, wireless, etc.

Note that a subset of these references, grouped in beginner, intermediate,
and advance categories are listed in subject C1 "What are some good getting
started ATM References?".

Please be aware that because of the pace of ATM standardization, reference
books and conference proceedings rapidly become out-of-date. However, the
following references offer a good base of background information. I have
retained some of the older references in this list since they provide the
foundation on which other applications of ATM have been based and therefore
should not be over looked.

General:
     "Issues and Challenges in ATM Networks", Communications of the ACM,
     February 1995, VOL. 38, NO. 2
          Surveys ATM concepts and networks, security issues, traffic
          management, TCP/IP over ATM, etc.
     "Data Communications Special Guide", IEEE Spectrum, 8/91, p.22.
          Hi-level overview of high-speed lans, wans, bisdn, atm, with
          glossary and bibliography.
     IEEE Communications Magazine, April 1992, VOL. 30, NO. 4
          This is a special issue with six articles on gigabit networks
          technology.
     Rainer Handel and Manfred Huber. "Integrated Broadband Networks: An
     Introduction to ATM-Based Networks". Addison-Wesley, 1991. ISBN
     0-201-54444-X.
     "Buyer's Guide for ATM Switches," Network World, October 9, 1995,
     p.47.
          Offers a general overview of what to look for in an ATM switch
          and lists products (with features and prices) from 23 vendors.
          The full text of the article (maybe a more up to date) may be

SUBJECT C3)

                      ATM information on the Internet

A) Here's a list of sites that that seem to cater to the
ATM/broadband/real-time continuous-media crowd:

wuarchive.wustl.edu          Research, ATM Hardware, Jon Turner papers
ftp.tele.fi                  Standards drafts (see below)
cell-relay.indiana.edu       cell-relay archives, etc. (see below)
info.bellcore.com            Standards drafts, etc (see below)
ftp.com21.com                ip over atm work and related ATM Forum
                             contributions can be found in ftp/pub/ip-atm

B) Best of all (thanks to the Information Janitorial Staff :-) is the
archive site for this list: the cell-relay retreat! This is a fairly
specialized WEB site in that you'll find only information on cell-relay or
broadband technologies (ATM/DQDB/SONET, etc.) including research papers,
standards, product information, mailing list archives, and events such as
conferences, workshops, etc. If this is what you're looking for, you're in
the right place!
If you have ftp access, ftp to cell-relay.indiana.edu as user anonymous and
look in /pub/cell-relay for:

archive           Archives for the cell-relay newsgroup
bib               cell-relay bibliography
conferences       Upcoming conferences and call for papers related to
                  cell-relay
docs              cell-relay research papers and standards
vendors           Vendor promotional materials
publications      Popular Books, Publications, Sources
FAQ               Containing this FAQ and other related FAQs of interest.

C) Additionally, there are some draft standards, RFCs, technical papers,
etc. on ATM available at ftp.tele.fi in the directory called /atm The
collection includes draft AAL5 CCITT standards. This is a general good
place to look.

D) Similarly, at thumper.bellcore.com in the /pub/smq/ directory has some
circa 1993 related ITU docs.

E) Most ATM equipment vendors have WEB pages where they provide access to
internally generated white papers on ATM and their own equipment. One of
these is FORE at http://www.fore.com/atm-edu/

F) A lot of good papers, documents, and forum contributions may be found at
Raj Jain's WEB pages at: http://www.cis.ohio-state.edu/~jain

G) See also question subject A6 in this FAQ for pointers to *other* ATM
related FAQ's.

H) And don't forget to check the ATM Forum at: http://www.atmforum.com

---------------------------------------------------------------------------
SUBJECT C4)

          How can I get the ATM Forum's Interface Specifications?

SUBJECT C6)

                 Internet drafts from IETF working groups.

Early versions of the FAQ attempted to list current IETF drafts which are
related to ATM. However the Internet Drafts change like sand running
through your fingers. I recommend using the IETF URL listed below to surf
the ID's yourself. Alternatively you can login via anonomyous FTP and
search for key IETF working groups. Try *ROLC*, or *ATM*, or *ATOM*, or
*IPATM*, or *ION*, etc.

Internet Drafts are draft documents valid for a maximum of six months.
Internet Drafts may be updated, replaced, or obsoleted by other documents
at any time. It is not appropriate to use Internet Drafts as reference
material or to cite them other than as a "working draft" or "work in
progress". Please check the lid-abstracts.txt listing contained in the
internet-drafts shadow directories on nic.ddn.mil, nic.nordu.net,
ds.internic.net, or munnari.oz.au to learn the current status of any
Internet Draft.

Useful URL:

http://ds.internic.net/ds/dspg0intdoc.html

Internet-Drafts are available by anonymous FTP. Internet-Drafts directories
are located (as officially designated by the IETF folks) at:

   * Africa Address: ftp.is.co.za (196.4.160.2)
   * Europe Address: nic.nordu.net (192.36.148.17)
   * Europe Address: ftp.nis.garr.it (192.12.192.10)

"The Asynchronous Transfer Mode: A Tutorial" by Jean-Yves Le Boudec
     Computer Networks and ISDN, Vol 24, No 4, May 1992, pp 279-309

Access the ATM Forum on the World Wide Web at http://www.atmforum.com and
then browse through the online info. The tutorial has some basic intro to
ATM.

Additionally there are reasonable tutorials available from several
commercial communications companies. Specifically:

  1. "Asynchronous Transfer Mode: Bandwidth for the Future", Jim Lane,
     Telco Systems, 1992. To order a free copy simply call 1-800-447-2537
  2. "Broadband Testing Technologies", (a HP Seminar Handbook), Hewlett-
     Packard Company, February 1993, Document number 5091-6902E Call your
     local HP sales office and or contact the HP IDACOM Test division. The
     inside cover claims this document costs $10.
  3. "Understanding ATM Networks", Bay Networks (SynOptics), part number
     893-687-A. You can order it from SynOptics Press or a Bay Networks
     sales office.

Additionally, Ameritech and the other Bell companies publish a pamphlet
called "ATM Today" anad another called "SMDS Today". You can call (800)
TEAM-DATA for copies.

ATM Forum Ambassador Program
     ATM Forum has an ambassador program whereby they provide informative
     speakers to the networking community regarding various aspects of ATM.
     Ambassadors represent the ATM Forum and present ATM technology in a
     non vendor specific manner. Ambassadors can discuss firsthand current
     activities in the ATM Forum. Topics include:

        o Why ATM
        o Introduction to ATM
        o Intermediate ATM
        o ATM in the public WAN
        o Signalling 3.0
        o Traffic Management 3.0
        o B-ICI
        o Network Management
        o LAN Emulation

Contact the ATM Forum for more information.

Last but not least, Derek Hill has gathered together some on-line
references in the teaching archive of his WWW server. It's designed for his
students, not for ATM experts!

http://www-ipg.umds.ac.uk/ (main server)
http://www-ipg.umds.ac.uk/~dlgh/teaching/atmref.html (ATM references)

Let him know (D.Hill@umds.ac.uk) if you have any comments or suggestions.

SUBJECT C10)

                         ATM and Related Acronyms.

The cell-relay archives contain an ever growing list of acronyms which tend
to appear in postings, RFCs, standards and other text related to the
cell-relay topic area. This list is at
http://cell-relay.indiana.edu/cell-relay/FAQ/ATM-Acronyms.html

Here are a few five dollar words which sometime arise in this topic area.

   * Plesiochronous: Signals which are arbitrarily close in frequency to
     some defined precision. They are not sourced from the same clock and
     so, over the long term, will be skewed from each other. Their relative
     closeness of allows a switch to cross connect, switch, or in some way
     processs them. That same inaccuracy of timing will force a switch,
     over time, to repeat or delete frames (called frame slips) in order to
     handle buffer underflow or overflow.
   * Synchronous: Signals that are sourced from the same timing reference.
     These have the same frequency. (Contrast with Plesiochronous signals.)
     Typically for synchronous data interfaces there will be a separate
     clock signal and the data need not be clocked at a uniform rate.
   * Asynchronous: Signals that are sourced from independent clocks. These
     signals generally have no relation to each other and so have different
     frequencies and phase relationships. (Contrast with Plesiochronous
     signals.)
   * Isochronous: Signals which are dependant on some uniform timing or
     carry their own timing information embedded as part of the signal. So
     isochronous data signals can be thought of as being "self-clocked".
     That is there is no spatially separate clock signal. A receiver would
     extract the uniform bit-rate clock from the actual data stream. Thus
     the two ends of a connection would run on the same clock, extracting
     data at a fixed (smooth) rate. (Contrast with Synchronous signals.)

SUBJECT C11)

  Literature and papers on the self-similar (fractal) property of traffic?

The volume of literature on self-similar data traffic is huge. Here are
some of the best and each of these has lots of other references. [1] is one
of the most important networking papers of the decade and launched this new
examination of data traffic performance. [2], from the same authors, is an
informal discussion of the importance of self-similar traffic modeling. [3]
provides a solid analysis of TCP-based self-similar traffic and includes a
number of useful appendices on underlying mathematical concepts of general
interest in self-similar traffic modeling. [4] focuses on the impact of
self-similarity on queuing performance and provides a good overview of the
issues and modeling techniques involved.

[1] Leland, W.; Taqqu, M.; Willinger, W.; and Wilson, D. "On the
Self-Similar Nature of Ethernet Traffic (Extended Version)." IEEE/ACM
Transactions on Networking, February 1994.

[2] Willinger, W.; Wilson, D.; Wilson, D.; and Taqqu, M. "Self-Similar
Traffic Modeling for High-Speed Networks." ConneXions, November 1994.

[3] Paxson, V., and Floyd, S. "Wide Area Traffic: The Failure of Poisson
Modeling." IEEE/ACM Transactions on Networking, June 1995.

[4] Erramilli, A.; Narayan, O.; and Willinger, W. "Experimental Queueing
Analysis with Long-Range Dependent Packet Traffic." IEEE/ACM Transactions
on Networking, April 1996.

The first paper listed above [1] was originally published in sigcomm93 as a
shorter paper. This and the longer version was the work which started the
whole self-similar perspective. The original sigcomm93 version can be found
online at: ftp://ftp.bellcore.com/pub/world/wel/

The updated longer version [1] appeared in IEEE/ACM Trans. on Networking
(and won IEEE's highest award for a research paper). It is on-line as
ftp://ftp.bellcore.com/pub/wel/

The author asks that you read the README:

ftp://ftp.bellcore.com/pub/world/wel/

This is also available in Adobe Acrobat for Mac/Windows folks (also Sun
Solaris and 4.1.3). It is be available as a link on:

http://cell-relay.indiana.edu/cell-relay/docs/TechReports.html

At SIGCOMM '94, Mark Garrett and others showed that MPEG is self-similar
ftp://ftp.bellcore.com/pub/dvw/

There have been several more papers (generally in ACM SIGCOMM proceedings)
show WAN traffic is self-similar and beginning to explore reasons why
traffic might be self-similar.

browser, try using a normal FTP application and log on with a user name of

SUBJECT C12)

                  How can I get copies of ITU-T documents?

You can buy these on paper from the ITU:

ITU
Place des Nations
CH-1211 Geneva 20
Switzerland.

The fax number of the sales office is +41 22 730 5194. They also have an
online publications services which is available by subscription. See their
FAQ at http://www.itu.int/publications for more information. Through their
service you can get documents at http://www.itu.ch/itudoc/itu-t/rec/q.html.
If you are not a subscriber you can send mail to sales@itu.ch to order a
paper copy.

It is also possible to get access to ITU documents available for
downloading on the Web without a subscription. You can pay for a single
document with a credit card. Refer to http://www.itu.int/publications for
more details.

They are also available commercially from at least 3 sources in the US:

   * Information Gatekeepers in Boston, MA (1-800-323-1088)
   * Phillips Publishing (1-800-OMNICOM)
   * Global Engineering Documents (1-800-854-7179)

Phillips usually has documents in stock & has fast delivery.

General online access is limited. Some postings suggested telnet to:
     ties.itu.ch / 156.106.4.75 or
     chi.itu.ch / 156.106.4.16

Some postings suggested the IMTC web site at http://www.imtc.org/. They
have most of the relevant H series and T series drafts available online,
plus some useful overview/tutorial stuff.

Others suggest using gopher because that is what they are using. For gopher
you'll need to use info.itu.ch if you want to use a local gopher client.
Click on the link in the last sentence to connect to info.itu.ch. ties and
chi will refuse connections to port 70.

Some can be accessed on http://www.itu.ch/ (ITU World Wide Web site). You
can also get copies of ITU documents using their auto-answering mailbox.
Send mail to itudoc@itu.ch with:

GET ITU-4313

in the message body to get information how to get the documents, including
I.363, that you want.

Alternatively, send e-mail to itudoc@itu.ch with the single line HELP in
the body of the message. That will get you information on the ITU's
automatic mail server. Essentially you send a message to the above address
with:

GET ITU-nnnn in the body, where nnnn is the document identifier number that
you get by asking for ITU-1100, which is the index to the ITU I. series,
including I.363.

ITU-4313 also has directions how to use gopher:
     Name=3DInternational Telecommunications Union (ITU)
     Host=3Dinfo.itu.ch
     Port=3D70

For a while there were many ITU documents available electronically. However
sometime in 1995 the ITU has taken these off line and they are no longer
readily available. If you have access to a cdrom (and an pc/mac) there is a
"Standard's" cdrom from Infomagic available for $30.00. This provides all
of the ITU documents which had been online as well as IETF documents. The
ITU documents include those published since 1988 (when they became
available electronically) through this summer. A few are missing (i.e.
X.741). Almost all of these recomendations are in postscript format, so you
will also need a viewer (ghostscript and ghost view are on the disks).

InfoMagic may be contacted at:

  Tel: +1-520-526-9565
  Fax: +1-520-526-9573
  E-mail: info@infomagic.com
  Web: www@infomagic.com

  InfoMagic
  11950 N. Highway 89
   Flagstaff, Ax 86004

Finally, don't forget to try the various Internet hosts on which ITU drafts
and other goodies may be found. A good place to start is ftp.tele.fi or
info.bellcore.com, check subject C3 of this FAQ for additional information.
