Bill, me thinks you may have an unfair knowledge advantage
over many of the members of the newsgroup! :) Sometimes, its nice
to know a network specialist! :)

Last night I was talking to a guy with a full digital circuit using
a USR Robotics at 128K with a terminal adapter and the best lantency
and ping times he could get were 120ms.  Of course the occasional
slam of traffic might give him a spurt of 2000ms ping but we should
be able to handle that at BRISTOL in a tight corner.. RIGHT.  This
person has the optimal setup full digital and it cost him about
$500 with a monthly maintenance fee of around $100.00.  This full
ISDN technology is still not good enough to prevent warping.  What
technological solution did you have in mind.  I think you have to
remember that most of the people that will attach to TEN will be
using analog circuits.  Whenever you are involved in A/D and D/A
conversion you lose lots and lots of latency.  The Best Analog
circuits seem to be around 150ms.  The Best ISDN circuits are
around 60ms.  Neither of these are good enough to prevent warping.
And 90% of the people that do HAWAII now cant afford ISDN digital.

So why dont you tell us what this TEN technology is that will make
everything ok.  

I for one want to know what we are about to get in the next 12 months
as none of my peers seem to know about it..

So far all we have is a lot of talk about how great its going to
be.  Maybe you can get him to say how and what.  

If he's think ISDN digital its isnt gonna work and can you
afford $100 a month to race....

Don Wilshe

I 100% agree with you... But it will take alot more than
CONCENTRIC and a ATM network to pull this off.

Well, as Chuck's thoughts seem to indicate he thinks the internet will
work... not. I don't agree that we can do this over the internet in its
current state... it just ain't gonna happen... the internet as we know it
today is bombarded with traffic that has no "latency issues" associated
with it.

My thoughts seem to go forward with private national networks. The
technology includes T3 and ATM backbones breaking down into T1 connections
to the point-of-presence (POP). There is one already out there... from
Concentric Networks... it supposedly can GAURANTEE low latency on EVERY
packet. I'm not connected at all with these people, I'm just a regular ol'
user like the rest of ya.

Search on Concentric to get their press release on the subject. There's
also more than just them making these national networks.

Don,

SATAN has been around for a few years now, and has been implemented
many times by both administrators and hackers both.  

My point?

A.  An Internet provider does not need a firewall to have adequate
security.
        A firewall merely provides a "shield" so that other machines on the
        "internal" network at the provider cannot be hit from the outside.

B.  Many providers already have firewalls installed and in place.  You may
        not be aware if your provider has a firewall or not, it is usually
        invisible to the user, and access times can vary by computer and
        software being run.

C.  You refer to the "internet".  The internet is no longer a single
entity, nor
        run by any single parent.  Some providers may choose to use firewalls,
        but since a firewall is going to add the cost of a computer and software,
        plus rerouting the network throught the firewall, many providers may
        choose alternate security methods.  Having a firewall does not preclude
        a sucessful attack from a hacker, either.  It merely provides a shield for
        the internal network.  A good comparison is a house.  If you have a house
        with 40 doors, that are all locked and have security alarms, is it more
        protected than a house with one door that was left open?  You bet it is...

I don't think you will have to worry about this.  Not to mention, the
advent of adding
major bandwidth to the internet over the next couple of years should
preclude any
slowdown.

Cheers!

Speed of light: 3 * 10^8 m/s

Equatorial radius of earth: 6378 km
Circumference of earth: 40074 km

Time for an electron to circumnavigate earth:  .13358 s.

That's 134 ms.

The latency is mostly in the routers, not in the travel
time.   There is still a lot of catching up technology has to
do before we run into physical constants.  So, let's look forward
to the international races in a few years!

Don't bother with satellites, though.  The altitude of a geostationary
satellite is 4.23 x 10^7 m.  The calculation of latency is left as an
exercise for the reader.

because they were affilieated with the Concentric Network....Now if YOU
think the ConNet is the way to go, and Papy thinks the same way....WHY IS
EVERYBODY ELSE SCREAMING ABOUT SLOW NET PLAY??

Absoultely. I signed up for Concentric here in Phoenix and
the connection was horrible. They gave me some song and
dance about upgrading the Phoenix POP but did not know
dates, details, etc. I told them to cancel the account.

Then you have a closed mind. What is the speed of light based on? That
relationship may never change but the underlying parameters could easily
change.

In 1899, the head of the US Patent office recommended closing the Patent
Office because everything of any use had already been invented.

You havent given me anything tangible yet other than alot of
double talk and will lets say I think we have lost you..

Later and never again..

Thank god we have Pete Reston that can explain things in
simple english.  Chuck, do you ever get any repeats jobs
as a consultant...
