What operating system support is required?
You can run the audio and video applications point-to-point between two hosts using normal unicast addresses and routing, but to conference with multiple hosts, each host must run an operating system kernel with IP multicast support. IP multicast invokes Ethernet multicast to reach multiple hosts on the same subnet; to link multiple local subnets or to connect to the MBONE you need a multicast router as described above. IP multicast is included in the standard IRIX kernels for SGI machines, in Solaris 2.3 and later, and in OSF/1 2.0. You can pick up free IP multicast software and add it to AIX 3.2, HP-UX, SunOS 4.1.x and Ultrix as described above. For PC machines running DOS or Windows, IP multicast support is included in the current release of the PCTCP package from FTP Software, but the application programs are still in development. No IP multicast support is available yet for NeXT or Macintosh. The IP multicast kernel software releases for AIX, HP-UX, SunOS, and Ultrix include a pat
