All things related to multicast

[Eli Dart <>]

232.2.3.2 is one of the groups associated with the JANET dbeacon instance:

http://www.beacon.ja.net/cgi-bin/m4

The JANET beacon appears to cover four of the five unique source addresses.

The other one, 193.17.9.3, appears to be part of EUMETCast (terrestrial multicast for EUMETSAT data): 

ftp://193.17.11.194/pub/OPS/out/user/EUMETCast_Support/EUMETCast_Licence_cd/Generic_Documentation/TD%2015%20-%20EUMETCast%20-%20EUMETSAT's%20Broadcast%20System%20for%20Environmental%20Data_v7A.pdf

So, I would say that there are two applications represented in that list of streams - one is a beacon instance, and one is a production data service:

Anyone aware of any active SSM streams to view for testing?  Details for viewing (source address, group address, port #, best app for viewing, etc) would be appreciated.  Looking at the I2 Router Proxy page, I do see a few live streams:
