Figure 1-8: Web Server/Client Transports
Unicast
In a unicast, each user or player client initiates its own stream, resulting in several
one-to-one connections between client and server, which is less efficient use of
bandwidth. Many clients connected via unicast to a stream in a local network can
result in heavy network traffic. However, this technique is the most reliable and
most common for delivery over the Internet because no special transport support is
required. For file or on-demand streams, each user can randomly access the media
content, playing only the parts they want. Unicast uses either TCP/IP or UDP/IP.
