Salo) Date: Fri, 05 Oct 2012 11:12:25 -0500 Subject: [e2e] TCP over IP over ATM In-Reply-To: <506EBF58.8070901@web.de> References: <506EBF58.8070901@web.de> Message-ID: <506F06E9.5070003@saloits.com> > Years ago, there have been some papers about TCP .......

As someone has noted, Raj Jain and his students published several articles on this and related topics. Dig through his home page. As I recall, many of these papers were published as ATM Forum contributions. The ATM Forum went away, but it appears that the documents are available online: There are a couple of challenges with ATM forum contributions. The first is that they aren't readily available. Most of the contributions were available only to members. And, it appears that Broadband Forum membership is required to access them today. You might ask the Broadband Forum whether they will let you access them at low or no cost -- I can't imagine that the documents are worth much today except to researchers. The other difficulty with the ATM Forum documents is that there are a lot of them. You should have a copy of "Dynamics of TCP Traffic over ATM Networks" by Romanow and Floyd. I think this paper focused on fragmentation, but you might did around to see what else they did on this topic (although I don't think it was much). And, of course, Google. Try [tcp atm abr] and [tcp atm congestion] for starters. -tjs From detlef.bosau at web.de Sat Oct 6 02:40:51 2012 From: detlef.bosau at web.de (Detlef Bosau) Date: Sat, 06 Oct 2012 11:40:51 +0200 Subject: [e2e] TCP over IP over ATM In-Reply-To: References: <506EBF58.8070901@web.de> Message-ID: <506FFCA3.5000303@web.de> First of all, I'ld like to thank for the many papers I've been pointed to. I'm still to read them in detail. My objective is not to study TCP/ATM in great detail, however it's the obvious analogy to wireless networks which is interesting. Up to now, people tend to think all networks to be wired networks - with invisible wire. The extremely strong assumption being so made is no more and no less that a link's service time and a link's workload capacity remain more or less constant as long as the packet size remains constant. Either assumption, concerning the service time and concerning the capacity, is wrong. This is hardly admitted by anybody from the wireless community - in ATM it is "don't care" because, at least to my knowledge, ATM fades out. However, before I fail to convince the community of adverse effects of link variations on TCP in mobile wireless networks again and again I thought it useful to have a glance on a wired "analogy", where the problems are basically pretty much the same. Not because ATM were error prone. But because ATM, particularly with ABR, may expose a behaviour similar to that of a mobile network with error correction to upper layers. Would you agree? Or would you contradict here?
