srt@ucla-cs.UUCP (05/15/85)
I've gotten about 20 requests for a SPUDNET map since the gateway at ucla-cs opened up, and I noticed an address request in net.net-people the other day, so I'm posting an abbreviated guide to SPUDNET here (Most of this is drawn from the SPUDNET Protocol Guide SXL-14). Further questions can be directed to me or to the SPUDNET moderator, Douglas Trainor (trainor!ucla-cs). These are the current major SPUDNET sites (as of 4/85): Name Poll Notes ucla-cs Demand Gateway to USENET. dddrcf Daily cldh Daily Abandoned Bell switching center (?) ihop Morning berke Morning Limited traffic allowed. russet Demand SPUDNET administration site, also has limited gate to USENET through vvlxtr. bbring Twice daily Ring of Apple-II bboards. bigmac Daily Goldman's. opark.6 ?? Been down lately. lexhax Midnight Timekeeper for SPUDNET. idaho Demand Mail only. lthouse Daily These are the secondary sites. Unless marked otherwise they are polled once a day on an if demand basis by one or more of the major sites: bbvxen hslpc klingon shltz croesus* lnwdl ppvax qbert rehier bigman yloh elbib kyle psato buranim** ianian * Password access only ** Canada Polling protocol is as given is SXL-7. A program implementing this in xlisp was posted to net.sources several months ago. A C version is under development at aqfc@lexhax.spud. Pathing is done at each site according to an algorithm that guarantees least time in transit between major sites (but does not guarantee quickest travel to secondary sites). A description and implementation of this algorithm was presented at the Second Symposium on Network Traffic Analysis (Terre Haute, 1983) and is available from the author at edmond@ianian.spud. If there is sufficient interest perhaps we should start up net.spud, which I'll arrange to port to SPUDNET. Scott R.
