Paul, >> I agree that ever having a source or destination IP that's RFC1918 outside >> the domain is a very bad thing. >I don't see anyone here disagreeing with that, but apparently a number of >ISP's did not consider the ICMP case when they gave numbers to their T1's, >and so it's a question of definition rather than of intent. Transit nets >are public, not private, and so they have to have public, not private, >addresses. I want to respectfully disagree. I do run internal routing protocols that can't handle VLSM or CIDRization permitting cutting up a class C into 64 disconnected pieces. , igrp in particular. Because of this I would burn too many network numbers by having to use public network numbers for all my T1's. I never permit a case where both sides of a router have RFC1918 address space so there is no confusion in a traceroute at to where to address questions about routing issues. Purity of addresses is valuable but I am willing to compromise on this in this instance. Walt

High orbit, geosyncronous sattelites do not stand much of a chance against land lines as the latency on the links is quite high. Low orbit satellites, however, can be quite effective competition assuming that they have enough satellites to get coverage. These types of satellites are the ones that Gates is thinking of launching as well as several other companies/consortiums. When we can all have > 1MB/sec connectivity wireless to our laptops/video portable phones, with global coverage, satellites will rule the day. Justin "I still like land lines" Newton Justin W.

Hi all, I have been following this thread with some interest. A few months ago a friend of mine from Fore Systems told me about the 'ACTS' project. NASA and Ohio-State and quite a few others were doing research into the Gigabit Satelite Network. There was a test between Sony in Japan and I 'BELIEVE' JPL in Pasadena of hight def video transmissions over an OC-3 circuit. I heard something about a quasi commercial deployment of another ACTS project. Anybody heard anything about this? If enough birds like ACTS were sent up, this could be a boon for ISP's maybe. Of course I live in this ideal world where everybody is reasonable, intelligent, and well yea I know things are just quite the opposite. If MCI/AT&T/NTT/GTE put this into motion then were doomed, but if Hughes (read someone who doesn't own an ISP yet) put one up, it might be a bit more promising.

My recollection is that ACTS is free for use by public universities, but that the footprint doesn't reach very far north, and that the latency is high enough that not very many schools are actually using it. -Bill

Unless the SMTP server used to proxy email through a firewall is able to strip headers, it's unavoidable.

| Worldcom and Cable & Wireless are in the process of laying a 20 Gbps Thanks for the ad. Now to try to make this more operations-relevant... Vadim Antonov and I had a brief exchange wherein I pointed out that the biggest costs (noted in part by others) of trans-oceanic cables are, principally, insurance, rental of cable-laying fleets, ongoing management and repairs, acquisition of landing rights, and restoration-bargaining. SDH (I know of no trans-oceanic SONET deployments, however people have been discovering that some ADMs don't care while others light up like Christmas trees when one is used instead of the other) helps reduce the costs of bargaining for restoration capacity, since a properly engineered route _ought_ not to fail across both paths for the most common reasons, however, even really well planned SDH loops will fail from time to time. This sort of technology (TAT-12/TAT-13 for example) is a huge plus. CWI has an "in" on fleet rental and on ongoing management, however it does not reduce the price to zero as CWI and its partners (e.g. SPRINT in PTAT Systems Inc.) can attest. Landing rights to London are relatively inexpensive. However, London isn't the only place in Europe, and it will be interesting to see how Worldcom manages keeping costs down on end-to-end international private lines between the U.S. and Europe. The technical aspects of the Gemini cable deployment between NYC and London are staggering. I expect that clever ISPs (UUNET anyone?) could arrange trial services on the first path when (if?) it becomes available at the end of 1997 or the start of 1998. However, it would be insane to bet one's business on the cable being fully reliable for some time, and doubly insane to bet on not needing a full restoration contract in place until several months after the second path comes up probably about a year later. AFAIK there are no practical means yet to acquire as much restoration capacity as there is bandwidth on Gemini and until other paths are brought on line an operator should consider acquiring backup either at the IP level or by spending real $ on a restoration contract. What would be dead keen, however, is people getting together to use whatever is available on Gemini initially as a size-large battle net to test out the next generation of IP routers and the like in a relatively public fashion. | All this means that we should see a significant drop in trans- | atlantic bandwidth (and even intra-europe) charges in the near | future. Intra-Europe charges will fall for many reasons beyond MFS's deployments. I would be interested in a formal and binding assertion that the Gemini owners will substantially undercut their competition's pricing structures, otherwise, frankly, this seems like the kind of hubris one shouldn't plan real networks around. Finally, for the "bandwidth-is-free" crowd, this only amounts to maybe 8 STM-16s (maybe more if people take chances and parallelize across the two paths rather than use the two paths for redundancy), which means this cable is really not that far ahead of the apparent bandwidth-demand curve. Consequently, don't expect the current model of being shy of taxable short-term high-capacity deals to stop as Gemini becomes available. On the other hand, that CWI is willing to continue taking large risks in developing private submarine cable systems and is able to find investment and risk partners bodes well for being able to continue terrestrial growth, and maybe alot less well for LEOs and similar technologies. This is good news for people building parts of the global Internet. Of course, a cream-skimming path that's being built, so perhaps I overestimate the degree of risk perceived by the two Gemini partners... Sean.

Well . . . most people may not think satellites stand a chance but Bill Gates and Craig McCaw seem to think they do. Teledesic is planning build a long-haul communications network based on low earth orbit birds. In the past neither of these guys have been too stupid so I wouldn't rule out satellite communications just yet.
