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? 73 and TNX Mark NK2Y ------------------------------ Date: Thu, 5 May 94 14:44:57 EDT From: crompton@nadc.nadc.navy.mil (D. Crompton) Subject: TCP/IP band plans To: tcp-group@ucsd.edu 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.
