Multicast Routing What is Multicast Routing? Multicast routing is a networking method that sends data to multiple recipients simultaneously within a network, optimising bandwidth and resource usage. Explanation This technique is commonly used for applications like video streaming, online gaming, and teleconferencing. It reduces network load by transmitting data only once and replicating it as needed. Practical Example of Multicast Routing A live sports streaming service uses multicast routing to deliver video feeds to millions of viewers without overloading its network.
