- The TRICKLE server is a 'concentrator' of FTP sites into central
- servers. Each server has its own (large) cache disk to store files
- that have been recently ordered by users, and is in communication
- with all other TRICKLE servers about the contents of its cache.
- When a user orders a file that is not in local cache, TRICKLE can
- usually forward this command to one other TRICKLE server that is
- known to hold the file. In some cases, "broadcasts" to all other
- TRICKLEs for this file is necessary, and if the file is new, or
- accessed very infrequently, it is requested from one of the 3 FTP
- slave-servers it has. These 3 are special servers who fetch the
- file via FTP and send it via NJE to TRICKLE.
-
- TRICKLE servers reduce load on FTP sites substantially: Their
- incoming-to outgoing file rate is usually 1/5. Meaning, each cached
- file is usually sent out five times during its lifetime in the cache
- disk.
-
- TRICKLE supports a wide range of delivery methods to the user.
- Besides the usual email+(UUE,XXE,BTOA,etc), it can also FTP the
- files to the user, or use NJE SENDFILE where possible and desired.
-
- It is possible to subscribe to file patterns, such as
- <MSDOS.VIRUS>SCAN and to have server deliver you a new copy of the
- file each time it is made available. A special keyword, '*' can be
- used instead of the pattern to subscribe to an entire
- subdirectories, like: <OS2.NEW>*
-
- It mirrors many FTP site's popular directories:
- (exact site names are described in the help file): MSDOS, MISC,
- SIGM, MACINTOS, LINUX, UNIX-C, GARFIELD, OS2, KERMIT, X11, IBM,
- VM-CMS, WUARCHIVE, EXPO-MIT, UUNET, TEX, AMIGA, ARCHIVES.
-
- The servers are accessible from any connected network, via email or
- NJE interactive messages. Send a:
- /HELP
- command in a mail message (with the leading slash) to:
- trickle@frmop11.cnusc.fr (or TRICKLE@FRMOP11.BITNET), or
- trickle@hearn.nic.surfnet.nl (TRICKLE@HEARN.BITNET) for a help file,
- and to assist you locate your closest TRICKLE server (there are
- currently 12 TRICKLE servers).
-
- Note! This server code is entirely different than the TRICKLE server
- written by John Fisher (which I called "FTP slave-servers" in this
- document). However, John Fisher's server is greatly used by TRICKLE
- servers to fetch the files.

- Hello Timo; yes, the information you have there is correct. Please
- note that in probably 1 month, trickle@frmop11.cnusc.fr will cease
- to exist.
