4.20 Multicast
Multicast (one-to-many or many-to-many distribution) is the group communication where
information is addressed to a group of destination computers simultaneously. Multicast can be used
for one-to-many networking applications such as online streaming video and gaming, and allows
more efficient use of resources when supporting these types of applications.
To configure multicast function, choose Advanced Setup > Multicast.
