Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of IP Multicast:
IP multicast is a method of delivering data from one source to multiple destinations simultaneously.
Unlike unicast (one-to-one communication) or broadcast (one-to-all communication), multicast isone-to-many, allowing data to be sent only to subscribers (multicast group members).
This significantly conserves bandwidth and reduces the load on the network because the source only sends a single stream of data, which is replicated by multicast routers as needed.
2. Use Cases for IP Multicast:
IP multicast is widely used in network services that involve real-time or large-scale data delivery, such as:
IPTV (Internet Protocol Television):Broadcasting live TV streams.
Real-Time Data Transmission:Delivering stock market data, sensor updates, etc.
Multimedia Conferencing:Supporting group calls, webinars, and online meetings.
3. Why the Statement is TRUE:
IP multicast reduces unnecessary traffic and maximizes efficiency, making it ideal for these types of network services.
