What component of the H.323 standard is known as the "brain" of the network?

The component of the H.323 standard referred to as the "brain" of the network is the Gatekeeper. The Gatekeeper plays a crucial role in managing communication within the network by acting as a central controller. It is responsible for several key functions, including call control, terminal address management, bandwidth management, and registration services for endpoints.

By centralizing these functions, the Gatekeeper enables more efficient control of call setups and ensures that communication sessions are properly coordinated. This capability allows for better resource management and helps facilitate communication between different endpoints within the H.323 network.

As a result, the Gatekeeper effectively orchestrates the interactions between different components, making it essential for maintaining the overall functionality and efficiency of the H.323 system.
