Multicast Configuration - CyberData 11021 Operation Manual

2.4 Multicast Configuration

Multicast groups use multicasting to create public address paging zones. Multicasting is based on
the concept of a group. Multicast addresses specify an arbitrary group of IP hosts that have joined
the group and want to receive traffic sent to the group. Group members send IGMP messages to
their local multicast routers, allowing the group traffic traversal from the source.
Multicast configuration provides the ability to join up to 10 paging zones. A paging zone can consist
of one, or many, CyberData multicast group-enabled speakers. There is no limit to how many
speakers can be in a given paging zone. Each multicast group is defined by a multicast address and
port number. Each multicast group is also assigned a priority, allowing simultaneously arriving
pages to be serviced based on importance. Multicast groups are compatible with IGMP through
version 3.
