Path: utzoo!utgpu!water!watmath!clyde!mcdchg!chinet!killer!vector!chip From: chip@vector.UUCP (Chip Rosenthal) Newsgroups: pubnet.config,news.admin Subject: the PUBNET network Message-ID: <374@vector.UUCP> Date: 24 Jun 88 22:16:01 GMT Reply-To: chip@vector.UUCP (Chip Rosenthal) Organization: Dallas Semiconductor Lines: 99 On June 10, I broadcasted a "sendsys" message through the pubnet. I have accumulated all of the responses. In summary, I have found: - There are 96 systems receiving the pubnet distribution. - There are two pubnet backbones. To determine the pubnet connectivity, I hacked together some scripts to generate statistics from the sys files. From this information, I manually created a "backbone" map. In a moment, I'll describe my definition of a backbone site, but first, here is the map: bu-cs ----- UUNET ----- lll-winken ----- DDSW1 ----- ditka petro ----- tness7 ----- KILLER ----- bigtex ----- qiclab I defined a "backbone" site as a site which exchanges all messages within at least one pubnet newsgroup (e.g. a link with the 'L' sys file flag is not counted) with more than five other sites, and at least one of those other sites is a "backbone" site. A "major backbone" site exchanges pubnet messages with at least ten other sites. Major backbones sites are capitalized in the map. By this definition, there are two backbones to pubnet. I went through the paths of all my pubnet news articles to see how messages are crossing from the UUNET/DDSW1 backbone to the KILLER backbone. It appears that messages are going DDSW1-->KILLER via two intermediate sites: ddsw1!lll_winken!netsys!killer. It appears that messages are going UUNET-->KILLER by four intermediate sites (ick): uunet!warble!rpp386!dalsqnt!pollux!killer. By the way my site is on the KILLER backbone, which is why I'm focusing on the -->KILLER flow. I don't think this connectivity is too great. There are two things which would fix this. First, it would be nice if some site could connect between killer and uunet. Second, we should promote netsys to an honorary backbone site :-).
