Unicast is the term used to describe communication where a piece of information is sent from one point to another point. In this case there is just one sender, and one receiver. Unicast transmission, in which a packet is sent from a single source to a specified destination, is still the predominant form of transmission on LANs and within the Internet.
Section I begins with a brief overview of Multicast and P2P networks. The multicast is a mechanism used to support group communication applications such as audio and video conferencing, multi-party games and content distribution. IP multicast is used to transmit IP datagrams from one source to multiple destinations in a LAN or WAN.

Multicasting - Advantages and Disadvantages In this section, We will discuss about Multicast, advantages and disadvantages. Till now we have seen what is multicasting and what are the benefits of using multicasting in network. Now let’s start with Multicast advantages -.
IP multicasting is a bandwidth-conserving technology that reduces traffic because it simultaneously delivers a single stream of information to thousands of corporate recipients and homes. Applications that take advantage of multicast include video conferencing, corporate communications, distance learning, and distribution of software, stock quotes, and news.
Multicast: Multicast is the middle ground between unicast and broadcast. Multicast traffic is destined to a “group” of hosts, called “multicast group”. Hosts register into a multicast group in order to receive the traffic which is destined to that group. Multicast is used in Video over IP communication for example.
Multicast is a type of communication where multicast traffic addressed for a group of devices on the network. IPv6 multicast traffic are sent to a group and only members of that group receive the Multicast traffic. Devices which are interested in a particular Multicast traffic must join to that Multicast group to receive the traffic.
Figure 3: Example of Broadcast One to All Transmission. Unicast vs Multicast vs Broadcast: What Are the Differences? After knowing the definitions of unicast, multicast and broadcast, we’ll make a comparison of unicast vs multicast vs broadcast.
