Unicast
Unicast is a one-to one connection between the client and
the server. Unicast uses IP delivery methods such as
Transmission Control Protocol (TCP) and User Datagram
Protocol (UDP), which are session-based protocols. When a
Windows Media Player client connects using unicast to a
Windows Media server, that client has a direct relationship
to the server. Each unicast client that connects to the
server takes up additional bandwidth. For example, if you
have 10 clients all playing 100-kilobits per second (Kbps)
streams, those clients as a group are taking up 1,000 Kbps.
If you have only one client playing the 100 Kbps stream,
only 100 Kbps is being used.


Multicast
Multicast is a true broadcast. The multicast source relies
on multicast-enabled routers to forward the packets to all
client subnets that have clients listening. There is no
direct relationship between the clients and Windows Media
server. The Windows Media server generates an .nsc (NetShow
channel) file when the multicast station is first created.
Typically, the .nsc file is delivered to the client from a
Web server. This file contains information that the Windows
Media Player needs to listen for the multicast. This is
similar to tuning into a station on a radio. Each client
that listens to the multicast adds no additional overhead
on the server. In fact, the server sends out only one
stream per multicast station. The same load is experienced
on the server whether only one client or 1,000 clients are
listening
