I have been trying to follow the 100mbit Ethernet work from a distance
and I am hoping that more information will come out about the three
proposals after the 802.3 meeting.  For those that haven't heard,
there are three groups making proposals.  They are according to 
Network World (Nov. 9,,1992):
Group 1:
    Sun
    3Com
    SynOptics
    LAN Media
Group 2:
    HP
    AT&T
Gruop 3: (not really a group :-))
    Grand Junction

There is also a fourth offering already shipping from MicroAccess,
Inc.  There are differences between the offerings but the details
are supposed to be made public at the meeting. From this and other
articles I have gathered that the Group 1 proposal and MircoAccess'
offering is done by adding additional wire pairs.  The Group 2
proposal uses the same wiring spec as 10BaseT (how I don't know).
Grand Junction has declined to comment on their proposal.

They also have some pricing mentioned.  The MicroAccess product,
OptiLAN Fast-Ethernet, a 16 bit card sells for $699.  HP is quoted
in the article saying that they expect their offering to be about
one to two times the cost of current 10BaseT offerings.

(BTW, I know my company is owned by AT&T but I have attempted here
to be informative and not make a sales/position pitch.  As for AT&T's
offering, I only know that AT&T Microelectronics is involved.)

What sort of benchmark test results have been published for ethernet systems?
I'm mostly interested in IPX, TCP/IP, and EtherTalk. I'm also especially
interested in "real-world" numbers, such as how long does it take to transfer a
certain sized file from a server disk to a local workstation disk. I know this
is frought with non-network variables (type of OS, disk access, cpu speed,
etc.) but I'm trying to understand what "real-world" times one might reasonably
expect to get from various systems.

(When I say "real-world", I am specifically NOT referring to published specs
about burst bit per second rates that include network protocol overhead.)

For instance, if you were transferring a file from one Sparc to another using
TCP/IP, on the same segment, with no other network traffic, should a 10MByte
file take about 15 seconds or more like a minute? Faster? Slower? How about the
same size file, from a Novell server to a Novell client (using 486/50s for
both)?

Or is this type of question totally unanswerable, without knowing every detail
of the hardware & software involved? I'm not looking for exact numbers, but
reasonable ballpark figures or rules-of-thumb. Thanks for any hints.

Are you loading the TCPIP.NLM on the file server and binding IP addresses
to both ethernet cards?  You need to do this in order for the Novell server
to route IP packets from one segment to the other.  I am assuming from your
description that the Novell server is the only connectivity between the two
ethernet segments?

That's not going to work for 10baseT. 3Com did use a system like that which
they sold under the name "pairtamer". It worked, but 10baseT xcvrs are
actually cheaper than these passive glorified baluns. 10baseT uses separate
pairs for TX and RX - whereas 3com was using only one pair, so you could use a
balun.

Well... We pay something like $300 for good, programmable ethernet NIC's. And
we pay well under $100 for a 10baseT-AUI xcvr. Not as neat as getting a new
card, but if there's nothing more than that to be gained.. Save the bucks for
a new mouse or something!

General answer for number of segments is about 12 segments that are

I'm running numerous 3C501's on my Banyan LAN -- they seem to perform
quite well, although I've never benchmarked them in any way other than
by "feel".  I know for a fact that I'm getting much better than 1

I don't understand why they're not -- did you get documentation & check
the jumpers?  If not, e-mail me the jumper settings & I'll tell you how
they're set up.

Any card that meets the 10Base2 Ethernet standard -- I've currently got
a mix of 3c501's, 3c503's, 3c503-16's & WD8003E's.  One advantage of the
3Com equipment is that as long as it's all 3Com gear on the segment, you
can go 1000' instead of 600.

You might consider checking out Little Big LAN from Information Modes
(800-628-7992).  Their latest release has now has Ethernet support (as
well as Arcnet, parallel port, serial port, or any mix of these).  Best
of all, it only costs $75 and you can install it on as many nodes as
you want (no per/node charges).  It is a peer-to-peer based lan and is
an excellent value for the price.

Novell can/will provide this upon request. You are not the first with

Hi.  I'm trying to figure out ways to get a Microsoft Mail post office to talk

SLIP is Serial Line IP.  A SLIP connection provides a way of
establishing an IP connection over a serial line, typically a modem
connection.  SLIP support is provided by terminal servers and routers
at the LAN end, and various companies provide SLIP client software for
PCs and Macintoshes and workstations.

You may want to consider using PPP (Point-to-Point Protocol) instead.
It provides some improvements over SLIP.  First, it is a
protocol-independant connection.  The improvement I find most useful
in the IP world is that the PPP protocol will negotiate the IP address
used by the remote side.  This allows an administrator to assign a
pool of addresses to be used for casual users, while locking in
addresses assigned to regular users.

Also look for CSLIP, which is SLIP using header compression.  This can
make a big difference for small packet applications like telnet with
remote echo.

A quite reasonable overview of ATM may be found in Fred Goldstein's book,
"ISDN in Perspective" (Addison-Wesley), in Chapter 8, "Broadband ISDN".

My only gripe with it as a "stand-alone" ATM reference (that is, reading
*only* Chapter 8) is that there is a lengthy section on the SONET Physical
Layer during which he uses a lot of SONET-internal terms (e.g., "path
overhead") without ever referring you back to the end of Chapter 3 where
the terms were defined (in a concise SONET tutorial, including a picture
of a SONET frame). A miniscule nit, perhaps, but irritating.

Oh, also, the book came out just as AAL5 was being proposed, and thus it
underestimates the impact that AAL5 is having. (It's barely mentioned at
the end of the the AAL4 section.) And in the speculation about the future
of B-ISDN (ATM) in Chapter 9, "ISDN in Practice", it makes no mention of
the increasing pressure from computer manufacturers and network component
vendors (e.g. the ATM Forum and others) to deploy ATM as *the* next-gener-
ation LAN... NOW!  One is left with the impression that ATM deployment will
come along in the telcos' own sweet time.

By the way, the rest of the book, on ISDN BRI & PRI, is nice, too.

	I admittedly don't have much to compare it to, but I've been
disappointed with HP's OpenView Hub Manager for DOS Windows. We went this
route because we were going heavily into EtherTwist and wanted something
which would absolutely support our hardware without costing an arm and a leg.
Aside from its aesthetic shortcomings, I don't care for the separate Draw,
Admin and Run utilities (I'd expect better integration). It provides only
limited functionality when dealing with anything beyond the basic HP hubs.

	We were also disappointed by the Dealer Only support in the absence
of support contracts. Since our (government) procurement office gave the
contract to a small-time dealer who's provided no support (when I could
reach anyone there), we're effectively left in the lurch. Heck, even
Compaq and Apple now provide direct vendor support gratis!

	Had we the opportunity to do it over again, we might have chosen
the David Systems software (priced similarly to HP's Hub Manager) and
chosen another vendor for the bulk of our ports.

The LANtastic setup will be much cheaper, probably.  I've worked w/ both, and
either would serve.  If you expect much expansion over what you mentioned, you
might as well go for the novell solution.  If not, then LANtastic would be
fine.

No, the stations on the LANtastic system do not have to be the same.  I've done
an installation for a company about the size you're talking about, and all you 
need is a mahine that can take the network card.  When setting up LANtastic
you do not have to make all of the machines available to every other one.  You
can set up only 1 machine as a server, and then you have essentially a novell
type setup, with the exception that the server is not dedicated, and can be
used as a workstation as well.  Setting up novell, unless you're talking about
novell lite, will requre a dedicated file server.  While its popular these  days
to try and get the biggest fastest machine available for a server, it really
isn't needed for a network of your size, no matter what they tell you.  You
could get by w/ novell 2.x for a 286 machine as the server, and performance
would probably be adequate for your # of users.

Drop me a line if you need any more info.
