Question: 1 / 400

What protocol does IGMP stand for?

Internet Group Management Protocol

IGMP stands for Internet Group Management Protocol. This protocol is critical in managing host group memberships within an IP network, specifically for multicast communication. It facilitates the process of hosts joining or leaving multicast groups and allows routers to track which hosts are interested in receiving multicast traffic.

The primary function of IGMP is to enable efficient data transmission by allowing routers to send multicast packets only to those endpoints interested in receiving them, thereby conserving bandwidth and reducing unnecessary traffic on the network. Understanding IGMP is essential for networking professionals working with multicast applications, such as streaming media or online gaming, as it plays a vital role in optimizing network resource usage.
