Does watmath get it's news from someone past (i.e. towards the US) UofT? I thought it was strange that the following article went to mailrus first, then to jarvis. Could watmath be using NNTP over Onet to iuvax? If that's the case, why not talk to jarvis instead? Just asking questions with no particular answer in mind...

Assuming Waterloo runs NNTP this would make perfect sense, but it can't happen until you guys finally take an hour and install NNTP (ditto for utcs) so jarvis can do less batching (radio.astro could take over the feed, but it sounds silly to cross n campus gateways when utme is one hubnet hop away from CSRI). If there were more NNTP sites on campus, it would be much easier to propate articles faster to York, Waterloo and other ONET sites, as it would be possible to share the load without paying the price of important added latency. If indeed Waterloo is fed from Illinois over the ONET link, then essentially all the data is coming over the US link twice. Even if there was ample bandwidth (which is not the case, given that the current link is 38.4 Kbaud), it seems silly not to have those two sites talk over NNTP, which would at least prevent some of the double transmissions. The optimal scenario is to have one "receiving hub" for each independant connection from ONET to other networks. Should the link to RISQ in Que'bec (and hence alternate access to the US via NYSERNET) materialize, another ONET site could be fed from there, providing redundancy without competing for the bandwidth on the outside-world links. Given the ONET topology, it would be conceivable to have jarvis.csri keep its NNTP feeds over the NSFNet connection, with ugw.utcs or gpu.utcs connecting to a site over on RISQ. Then news could be efficiently pushed to the rest of ONET. I think it would be time for the news admins on sites with access to ONET to start discussing ways of rationalize our feeds (NNTP has the potential of changing certain things in important ways).

I'm not at watmath, but: The only full feed watmath exchanges other than with U of T is with att (clyde, or at least that's what it used to be called) in order to make a loop through Canada -- it's deliberate, so that if one link goes down the other stays up. BUT: Because sahayman@watmath went to iuvax, they set up a simple feed so that *local* articles (posted within waterloo) go to iuvax, via internet, which means that they pop through Toronto on the way. Wasteful when they make it back to Toronto, but it's only for local articles. -- Brad Templeton, ClariNet Communications Corp. -- Waterloo, Ontario 519/884-7473

watmath feeds locally generated news articles to iuvax ( Indiana U ) via
UUCP/TCP. This will probably change to NNTP *real soon now*
( You hear this Steve ? )
The site 'orchid' you saw in the path is at UW.
Very soon news feeds here will be re-arranged alot, before I leave in 2
weeks to live in Switzerland. Hopefully most of the internet connections
and local news feeds will move to other machines instead of poor watmath
( whose &*%^*%* load average is around 10 right now at 11pm )
