Caching in Europe?
by Mike Schwartz 29 Apr '93

29 Apr '93

Hank Nussbacher just sent me figures from the April Internet Hunt results, indicating that Switzerland, Denmark and Finland each sent more data into the NSF backbone than they retrieved from it. The figures weren't broken down by service, but I suspect this is because of FTP. If any network admins in Europe have more information on this, I would be interested in hearing. It sounds like an ideal opportunity to cache FTP traffic. FYI, Peter Danzig, Rick Hall, and I recently completed a study about FTP caching, showing that reasonable sized caches placed at network entry points could reduce FTP traffic by 42%. The paper is available by anonymous FTP from ftp.cs.colorado.edu in the directory pub/cs/techreports/schwartz/PostScript/FTP.Caching (compressed PostScript) or in the file pub/cs/techreports/schwartz/ASCII/FTP.Caching.txt.Z (compressed ASCII). - Mike Schwartz Univ. of Colorado - Boulder

It's sort of "common knowledge" that the traffic out of Finland is always a lot more than traffic to Finland, and indeed this is due to the ftp archives they have there. So I would say that we do have an excellent cache in Europe (Finland). How about NSF doing some caching, so people from over there didn't have to pick up everything from Finland ? :-) -------- Bjorn Eriksen SUNET/NORDUnet Operation Center, KTH, S-100 44 Stockholm Phone: +46 8 7906513 Fax: +46 8 241179 ber(a)sunet.se /S=ber/PRMD=sunet/ADMD=sunet/C=se/

See pub/zone/iso-country-codes on ftp.nisc.sri.com. Why do only 28% of the advertised hosts answer a ping? Many advertised hosts are behind firewalls that only allow email to get through. Technically, they would not be considered hosts that are directly on the Internet. Some pings are probably lost due to links being down, and/or problems with the pinging process. Where can I get more information? See the pub/zone directory on ftp.nisc.sri.com. ------- End of Forwarded Message

Before the dinner there will be a guided tour of the house, which is situated in the heart of Amsterdam on one of the most beautiful canals.
