Most campus networks today support
intranet applications that operate between one sender and one
receiver. However, this paradigm is rapidly changing. In the
emerging campus network, there is a demand for intranet and
multimedia applications where one sender will transmit to a group of
receivers simultaneously. These types of applications include
transmitting a corporate message to employees, video and audio
broadcasting, interactive video distance learning, transmitting data
from a centralized data warehouse to multiple departments,
communication of stock quotes to brokers, and collaborative
computing. Another example might be an internal technical support facility
that uses multicast file transfer software to send software updates to
multiple users in the campus simultaneously in one stream of data.
