Multicast

  • Default networking protocol for the Media tools on the Access Grid.

  • Saves on internet traffic. Example: if you have 2 AG’s on the one campus, instead of being send 2 two separate data streams, one stream is sent, the edge router then sends the data to both sites.

  • Reduces data traffic, but increases CPU usage on Router. (In one case, a 20% increased CPU usage on a Cisco 6509 was seen)
