Can anyone recommend some of the better ethernet cards out there?
What I'm looking for is a high performance 16 bit ethernet card that
has the ability to buffer as many back-to-back packets as possible while
still forwarding to the CPU via the bus.  I've been doing a little testing
of the Western Digital 8013 Series cards and I'm noticing that it can
only handle five back-to-back packets.  A good test that I've been using
is "/usr/etc/spray -i -l 512 -c 32 host" from my Sparc2.  I decrement
count "-c" until I see that no packets are being dropped.  The Sparc2
can generate packets very fast with very little inter-packet delay.

Ethernet cards that can't handle at least 4 or 5 back-to-back packets
can cause problems with FTP writes from a Sparc2 towards a PC.  The sparc2
can generate all four packets to fill an initial TCP window so fast that
the card can miss the 2nd, 3rd, or 4th packets consistently and cause
the ftp session to hang and eventually time-out.  I just encountered this
problem with the D-Link pocket ethernet adaptor.  I haven't tested that
many other PC ethernet cards so I'm not sure how many elicit this sort
of behaviour.  I am wondering if there are cards/chips that can handle
anywhere from 8 to 16 back-to-back packets?

I've also been evaluating pocket ethernet adaptors. So far I've tested
the D-Link (DE600-TP) and the Xircom (PE2-10BT).  The Xircom can handle 5
back-to-back packets but seems to have a little slower transfer rate over
the parallel port than the D-Link adaptor.  I am getting a Solectek to
look at as well.  Has anyone else taken a close look at all the pocket
ethernet adaptors?  What about the ACCTON adaptor?  Does anyone know how
many back-to-back packets it can handle?  Are there any other POCKET
adaptors I don't know about?  This really isn't any sort of official
evaluation.  I wanted to purchase my own ethernet card and pocket
ethernet adaptor and just got interested in finding out which ones
could do the most?
				Thanks in advance,

Subject: Decnet/MOP across bridge?
Date: 9 Apr 92 13:15:10 MDT

I have an NCD X terminal on an ethernet segment that I wish to boot via Dec's
MOP protocol, from a VMS-based VAX on a different ethernet segment.  The two
segments are connected via a bridge (PCbridge).  Booting via MOP will not work
across the bridge.  A quick look at a PC ethernet monitor shows no ethernet
packets from the NCD terminal are getting across the bridge.  All works well
when I replace the bridge with a repeator (as expected).  My question is:

Why can't a MOP type packet pass across an ethernet bridge?

Also, after the NCD is booted, Decnet changes it's tune as to weather or not
the NCD is part of Decnet based network.  With the repeator, the NCD shows up
as a valid end node, but with the bridge the NCD is unreachable.  I suspect
that this problem will be answered when I find the answer to my first question.

I'll eventually fix the booting problem by getting a Sun Sparcstation on the
same segment as the NCD X terminal, and booting the terminal off the Sun via
TFTP.  However, I'd like to be able to use Decnet as the Decwindows transport
from the Vax on the other segment, across the bridge to the NCD.

Many thanks to anyone who can shed a little light and, as always, I'll
summarize if/when there is sufficient info.

I just received a demo for HP's JetDirect card.  This apparently is
an ethernet card that you plug into your HP laser printer, thereby
turning it into a device you can place directly on your LAN.

It looks pretty neat: faster speeds than parallel, and easy relocation
are two things that come to mind.

We're looking at getting one since we want to move our printer to the other
side of the office and can't string that long a parallel cable, and don't
want to go serial.

Anyone out there in netland have one of these things installed?  If so,
how well does it work?  What kind of speed enhancement (if any) did you
get?  Oh, and what kind of networkOS are you using?

Any information appreciated.  Thanks.

I have summarized the repeater rule in our internal Ethernet spec.

"No two nodes shall communicate through more than two repeaters."

You could have one-hundred repeaters per segment on your network, provided you
have no more than 1024 DTE's, just make sure that the path from one DTE to
another DTE goes through NO more than two repeaters.  

You can view fiber repeaters as one-half a repeater, the fiber is the IRL.  Or
if you have a DEMPR to thin wire or a Twisted pair repeater to twisted pair,
this would be one repeater.  

It is not how many repeaters you own, it is simply how many repeaters are in
the path of communication.

Organization: Communications Research Laboratory, McMaster Univ

What are the available options for a low-cost LAN to allow MACs and MS-DOS
PCs to share files and printers when there are only 2-5 stations on the LAN?
I am aware of TOPS but have heard that it consumes excessive memory on the PC
and has compatibility problems with Windows 3. Are the Windows problems just a
side effect of the memory usage which could be overcome by lots of RAM and
memory management software (e.g. QEMM) on a 386?

Are there any other solutions which price out at say, less than $500 per
station over the full 2-5 station range (NetWare with a dedicated server is
therefore right out!)?

Suggestions and advice are appreciated and I will summarize to the net if
requested.

Thanks in advance for the assistance.

Do the X terminals have 10BaseT tranceivers on them?  If they do, then
you could get a small (4 ports or less) 10BaseT MAU for around $500 and
hook two of the pairs to that.  If they don't have twisted pair
tranceivers, externals that plug into AUI ports are around $100-$200
depending on the source.  There are also repeaters that have twisted
pair and whatever kind and number or ports you need. Be careful that
you don't exceed the repeater limit (MAU's count as repeaters).

One possible solution would be to use PCBridge, KarlRoute, or other
bridge with whatever you need for the X terminals on one side and
10BaseT on the other.  PCBridge and KarlRoute are free, and just need a
dedicated MS-DOS machine with two or more ethernet cards.  Such a
machine would be about $600 (2x$150+$300) if bought new.  A bridge
won't count against the repeater limit either since it creates a
completely seperate ethernet.

I assume that the wire already installed actually is 10BaseT compliant
and already has ethernet on it.

Don't buy a bridge. Buy a router. Preferably a HP 27286A TR. Routes both
IPX and IP as fast as any bridge can forward and it does the job right.

Watch out I'm gonna plug my company's products, but hey this guy asked....

Actually 3Com makes a beast that is just up your ally. It is called the
PairTamer (part# 3C584) basically it is a precision balun that extends
10Base2 (yes I meant to say 10Base2/thinnet not 10BaseT) over TP wiring.
What you would do is this:

   10Base2               TP wiring               10Base2
  ----------PairTamer==================PairTamer---------------


Using this scheme you can have up to 30 10Base2 nodes at the remote
end of the link. By the way the PairTamer only uses a single pair (you'll
have 2 pairs left over).

You can call 800-NET-3COM (or 408 764-5000) and ask for more info. Ask for
the data sheet on the the PairTamer since it contains the graphs that show
distance limitations etc. The distance limits are a function of the lengths
of the 10Base2 you have. The shorter the 10Base2 the longer TP run you can
have. Additionally 22 guage TP can run farther than 24 or 26 guage. There are
some nice graphs in the data sheet that outline all of this.

You can also ask for the names and numbers of dealers in your area or for
the names/numbers of distributors. The list price for the PairTamer is
$150.00 for 2 (makes sense since they are only useful in pairs).
If you decide to go this route shop around a bit and you should be able
to buy them under list price.

Date: 15 Apr 92 01:54:57 GMT
Organization: Monash University, Melb., Australia.

I have a problem with Windows that somone may be able to shed some light on.

We run a small 10base5 Lan using 10NET software which Windows recognises as
an IBM PC LAN equivelant.

When I try to print to a remote printer on the Lan using a Windows
application (eg. Lotus 123 for Windows) it talks directly to the local
printer port (LPT1:) even though the local LPT1 has been logically re-assigned 
as LPT1 on another PC on the Lan.

As near as I can figure out, Windows expects to see the printer as a device
on the Lan in it's own right whereas 10NET treats a PC as a NAMED device on
the Lan but the printer is just attached, it doesn't have a unique name
that Windows can recognise.

My question is am I able to get around this problem? How does an IBM PC LAN
solve this problem (assuming it's a relevant comparison)?

You might want to take a look at the Milan Technologies MicroTwist II
transceiver if you're using 10BT.  It has one 10BT input and two DB15
AUI outputs.  I've been using one of these for about a year now and
it works great.  As long as your X-Terminals have an AUI input, this
will work fine.  You could also take a look at the Shiva Hublet product.
It takes one 10BT input and creates 4 10BT outputs.  Does anyone know
of a similar product that will split one 10BT input into 6 10BT outputs?
