3. Discuss the flow control mechanism used in SLTP. Why do you think it is different from the algorithms used for TCP? [5 Marks]

Answer:

Solved Step by Step with Explanation: congestion window vs round trip time sequence numbers, flow control mechanism

3. The flow control mechanism used in SLTP (Selective Layer Transport Protocol) may differ from the algorithms used in TCP due to the specific requirements and characteristics of SLTP. SLTP is a protocol designed for layered multimedia delivery, where different layers of multimedia data are transported simultaneously. It focuses on providing efficient and reliable delivery of multimedia streams while ensuring synchronization and quality of service. The flow control mechanism in SLTP may prioritize real-time delivery and synchronization of multimedia data over congestion avoidance. It may employ strategies such as prioritization of certain data packets, dynamic buffer allocation, or adaptive rate control to optimize the delivery of multimedia streams. Unlike TCP, which aims for fair and efficient resource allocation across multiple network flows, SLTP may prioritize the timely delivery of multimedia data to ensure a seamless user experience. This may involve adjusting the flow rate dynamically based on the characteristics of the multimedia streams, network conditions, and user requirements. The flow control mechanism in SLTP is tailored to the specific needs of multimedia delivery, focusing on real-time synchronization and quality of service, which may differ from the congestion control mechanisms used in TCP.
