Hi folks. I'm trying to set up a tcp/ip station here in East Greenbush,
(Yeah, it's a real place.) New York. (FYI, it's just outside Albany.) I
noticed that there isn't a lot of NOS activity here although there is an
extensive ax.25 network with LANs, THENET NODEs, PBBSes and DXClusters.
There is some concern locally that tcp/ip activity does not impact negatively
upon the existing system which relies on LANs and users ports to minimize
data collisions. I'm wondering how this issue is being addressed elsewhere.
Are special frequencies being set aside? Are NOS stations communicating via
the IP routing available thru THENET? Are NOS stations passing from one to
another as a net? What's happening guys?

A properly configured NOS TCP/IP system has no more (and probably less)
impact on a network than netrom/ax25 traffic. NOS with it's backoff
algorithums is actually more friendly than the other modes. Because of
this the other modes will actually impact NOS much more than NOS will
impact them.
NOS preferably should pass IP traffic directly between nodes throughout
a network, but because this requires a NOS station or equivalent (x1j etc.)
at each site, it is not always done this way. The alternative is to use
an existing netrom network to pass IP traffic. This has the advantage of
built-in routing but the disadvantage of small MTU's limited by the netrom
code. This is not a limitation on the X1j netrom/ip routers.
So in short the answer is that it coexists on one network down here without
problems. You may want to segregate the local user channels. We have a
2400 baud TCP/IP user channel and soon 9600 baud. Because thay are NOS
and running the netrom code the users can use netrom connects also.
