A. Unicasting
Unicast transmission is the sending of messages to a
single network destination host as shown in Fig 3. This
method solves network traffic problems to deliver messages
from one host to another. So, we can say that this is one-toone data delivering method. For better understanding,
consider a situation where one computer’s request for a site
is received by all connected to the Internet. This way you are
actually flooding the Internet with such requests. Hence, you
need Unicast transmission [12] for small and large networks.
Examples of Unicast transmission are HTTP, SMTP, etc and
it is still predominant in LANs.
