Final answer:
The Real-time Transport Protocol (RTP) is designed to guarantee that data is delivered within a specified amount of time, which is essential for applications that require real-time communication.
Step-by-step explanation:
The protocol that provides a guarantee that data will be delivered within a specified amount of time is known as a real-time protocol. These are typically used in systems that require real-time communication, such as VoIP (Voice over Internet Protocol), online gaming, live streaming, and other time-sensitive applications. In contrast to protocols that ensure reliable delivery, such as TCP (Transmission Control Protocol), real-time protocols like RTP (Real-time Transport Protocol) prioritize timely delivery over absolute reliability. RTP, for example, is designed to provide end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services.
