Multicast
Multicasting is a form of limited broadcast. UDP is used to send datagrams to all hosts
that belong to what is called a "host group." A host group is a set of one or more hosts
identified by the same destination IP address. The following statements apply to host
groups.
Anyone can join or leave a host group at will;
There are no restrictions on a host's location;
There are no restrictions on the number of members that may belong to a
host group;
A host may belong to multiple host groups;
Non-group members may send UDP datagrams to the host group.
Multicasting is useful when data needs to be sent to more than one other device. For
instance, if one device is responsible for acquiring data that many other devices need,
then multicasting is a natural fit. Note that using multicasting as opposed to sending the
same data to individual devices uses less network bandwidth.
