Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network. Multicast Group Limit You can limit the number of multicast groups a subscriber on a port can join. You may enable/disable the multicast group limit on individual ports. 84 NetAtlas EPON Manager User's Guide
