From: "Jan David" <jdavid@sr.net> To: sghuter@nsrc.org (Steven Huter) Date: Mon, 20 Jan 1997 23:49:53 -0003 Hi, > 1) A brief technical description of your current network Two networks are operational, a full-fledged network (200.1.156.0) and an e-mail only network (200.1.158.0). Both consist of 2 Sun Sparcstation 5 workstations and a livingston Portmaster 2e, with respectively 30 and 20 ports. Both networks use standard 10 Mbps UTP ethernet and are interconnected via an ordinary 8 port hub. The AUI plug of the hub is connected to a fiber-optic transceiver which in turn connects to a multimode fiberoptic cable that connects the networks to a Cisco 4000 router. The router is located at Telesur's F2 earth station (the buildings only lay about 50 meters from each other). Both networks connect to a different ethernet connection at the router. Serial port 0 of the router is connected to the TimePlex multiplexer of the F2 (IBS) earth station that gives us an 128 kbps link via the 325.5 E Intelsat satellite to Pittsburgh International Teleport (PIT), which of course is located in Pittsburgh U.S.A. PIT multiplexes our 128 kbps datastream into a T1 trunk which connects to the MCI backbone at WillowSprings (still in the U.S.A. of course). > 2) A brief technical description of the equipment/platform you are using > for your servers, routers, modems, etc. * four Sun Sparcstation 5 machines with 64 Mb ram and a total of 10 Gb diskspace. * two Livingston 2e portmaster with 30 and 20 ports respectively. * 50 Cardinal V.34 modems. * 1 Cisco 4000 router. * 2 hubs * 2 fiber-optic transceivers * 1 APC Matrix UPS with extra runtime batteries. > 3) Information about the pricing/costs of using your network. If you are a > volume bandwidth provider, i.e., what does a 64kb line cost ? And the costs > to dialup users ? * 64 kbps : $3000 a month. * full-fledged dial-up access: $25 a month with 2 hours free on-line time, after that, 20 cents a minute. * e-mail only access: $10 a month, 20 cents a minute. > 4) Can you describe the current state of academic/research networking in SR? The university network consisted of a UUCP connection to the University of Puerto Rico. The set-up was a MS DOS machine running Waffle (a BBS program), a 9600 Telebit modem and 1 telephone line to dial in (oh boy, glad those days are over). Later on, there also was a 386 machine running Waffle and a 486 running Linux 1.3.18. Both these machines used UUCP in turn to retrieve mail from the primary Waffle/DOS machine. The whole set-up was administered by the director of university computer center, Mr. Gerold Van Dijk and some volunteers, most notably, Andy Lo A Foe. There existed also a small group of volunteers that experimented with new ways to connect (they worked on the Linux machine). Unfortunately, mr. Van Dijk never got the money together to get a leased line, or better, never dared to make that financial risk, though at that time there were already between 200 and 300 users that paid every month per kbyte for sent and received mail. When Telesur started its on-line service in october 1995, Mr. Van Dijk lost all his customers almost overnight. That effectively killed the whole internet set-up of the university.
