All things related to multicast

Cool. I'd also point you to this page:

        http://water.mcs.anl.gov/~olson/beacon-php/beacon.php

which allows you to select a subset of beacons to view.

This works by my having added a hack into the beacon server that writes a 
text-format dump of the server state once per minute. You can find this at

        http://www-unix.mcs.anl.gov/~beacon/table.out

For the folks wanting to do archiving of beacon data, this should provide a 
means for getting the raw data. The format should be pretty 
self-explanatory; the tuples of data at the cross points are loss rate / 
delay / jitter/ out of order/ duplicates. The tuple is preceded with an "S" 
if the entry is stale (grey cell).

If you run an AG node and are not listed in the list of nodes, send me a 
note with your beacon name and I'll add you.

This interface currently only shows the loss rates. Anyone who's interested 
in adding more  support, the code is at

        ftp://ftp.mcs.anl.gov/pub/AG/beacon-php-2001-0410-0.tar.gz
