 I can see a advantage to having the whole network on the same software
problems are solved faster and  up time can be at 99%+   numbers are the way
of the future  years ago we tried that but the software of those days  didnt
work  but sure the techonology woud today and how hard would it be to get a
routing system based n ip address's .
 the only sad thing i see is a migration away from bbs systems over the
years  the users went away so did the bbs systems , Maybe one day it will
return god  I miss the late night keyboard sesions to all aparts of the
world  but those days are gone forever .
    Get a system working and lets all get on the same wagon  and make it
work .
   I no longer get active because of health problems  but
 one day I may return to the air in this remote west central florida area
still got all my junk ,
  personally I dont care how they do it up north! This isn;t the north! but
thats my 2 cents worh and I am sticking to it

Bill,
I will let you decide on how you want to handle this, but this is the
same crap that Bud got from the people who changed the node at
Cocoa and Melbourne to Flexnet, we have a state full of FPAC or
even X1J and they moved two sites in the middle of nothing to Flex.

Bud wanted to know if there was a way to go through the Flex stuff
in order to link two FPAC switches, I do not think that Flex will trans-
port the 01 PID of ROSE/FPAC. more below...

Of all of the solutions at least ours is based on ITU protocols (X.25 and
X.121) and will transport all of the rest. I can not say so for the rest of
them and those that do are a real pain in the but to do.

Now he is getting in to the old "They don't do it that way up naawth"
syndrom, to which my retort is go back up nawth if you do not like the
way we do it. ROSE now FPAC was born here in Florida based on the
old GatorNet product which turned into COSI and then ROSE.

FPAC is no more deadend than Flex, indeed show me where FLEX is
used as a commercial protocol (FPAC uses X.25 as the netowrk and
X.121 as the addressing, both are used in the GSM/GPRS/EDGE world,
if you are running a GSM phone is HAS a X.121 address buried in it
somewhere in order to do data).

Not only that but if you learn how to do X.121 addressing the IP addressing
will not be that big of a step to take, but if you are used to some
rinkydink
networking system like NetRot or Flex which routes on of all things
callsigns
then you are in for a rude awakening...

In the end I think our desire is to move the whole thing to IP and FPAC will
just be a transport layer for IP like eithernet or ATM or any of the
numerous
protocols that form the backbones that IP rides over. The advantage that we
have over the others is that the guys who did FPAC and ROSE understood
that they were working with a real world network that might some day have
to talk to othe real world networks and so they tried to make it work as
near
as possible to real world with such as IP.

As we have discussed many times in the past, the move to LInux will allow
for the using of other protocols as we get the foundation laid. The
foundation
being functional Linux machines, initially doing FPAC and of course IP along
with Netrom, though probably the latter will not be turned on until we have
the
other stuff debugged. We can add flex to it as we get a chance as it too can
run in there, the idea being to provide as many possible network solutions
as possible.

The networking tables for ROSE/FPAC are quite simple and only need to
know enough about the network to route a packet down the path that needs
to get it there. We do not have to store the entire network universe in each
node in order to route a packet, just enough data about the route to start
it going that way. I know that Flex has the automatic network building piece
I would like to see that put in FPAC, perhaps we can get someone to look
at the code and get it in there, I think that the WP is a step that way, in
the end once that is done, all you would have to do is tell the new switch
about it's neighbors, and tell each neighbor about the new switch then they
should exchange the proper data and the new switch would build it's routing
based on the neighbors data, and the neighbors would add the new switch
to the routing and also propagate that data on down the line, there is a
point
at which it will no longer need to be propagated because the addressing to
get a packet to that switch is too granular to need to have that fine of
data.

The Flex guy that was here at the Networking Conference was a real asshole,
when we asked him about using X.121 addressing on Flex rather than callsigns
he was real condecending and treated us like we were from some real remote
place, but I always compare his protocol to ours and see that the real world
is based on numerical addresses, and all of the routing is done that way. I
have yet to see a network that routes on callsigns, strictly speaking you
COULD
do it at least at the country leve, but then if you try to use the
rest of the call
you are screwed, hey!! look at me, I am kp4djt, now a router based on
callsigns
would say hmmm K = USA, KP4= Puerto Rico, all I will route this packet to
USA/PUERTORICO, but I am in Florida so that one gets shot out the door...

Yes the internet uses domain names, but they always map to a address, there
is no escaping it numbers rule when it comes to routing.

Well, I waxed long on that one, but these yankees piss me off when they
pull that 'up nawth' stuff. If they don't like it they can shut up and go
back
to where they came from.

See ya tomorrow or Sat a.m.
