Network Signaling Protocols are essential communication rules that enable devices to exchange information over a network. They define how data is transmitted, ensuring that messages are sent and received accurately. Common examples include Session Initiation Protocol (SIP) and H.323, which are used in voice and video communications. These protocols help establish, manage, and terminate connections between devices, facilitating smooth interactions. By standardizing the way devices communicate, Network Signaling Protocols enhance interoperability and efficiency in various applications, including VoIP and video conferencing.
