![]() ![]() To help explain how multicast works, we've split this section into three different topics: With multicast, the hosts can select whether they wish to participate in the multicast group with the use of the Internet Group Management Protocol (IGMP) protocol.īelow is a simple example of a group of hosts (host A and D) being part of a multicast group who receive and process a stream of data: While a broadcast is directed to all hosts on the local segment, a multicast is directed to a group of hosts. Some describe a multicast similar to a broadcast in that it targets a number of devices or hosts on a network, but not all. Note: Understanding Multicast requires solid knowledge on the structure and purpose of MAC Addresses. In this article, we will discuss the importance and benefits of multicasting, as well as its use in different network applications. ![]() Multicasting is widely used in various network protocols, such as IPTV, video conferencing, and online gaming. Multicasting is an efficient method of sending data to a group of devices, as it reduces network traffic and ensures that data is delivered to all devices in the group simultaneously. The data packet is then forwarded by network devices to all devices that have subscribed to the multicast group. In this method, the sender sends the data packet to a specific multicast address, which is assigned to a group of devices. ![]() Multicast is a communication method used in computer networking where data is sent from a single sender to a group of destination devices. ![]()
