- 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.
