Which transport layer protocol controls reliable end-to-end data transfer using sliding window flow control and congestion avoidance algorithms?
Which transport layer protocol controls reliable end-to-end data transfer using sliding window flow control and congestion avoidance algorithms?
Multiple Choice Options
- A✓ Correct Option
TCP (Transmission Control Protocol)
- B
HTTP (Hypertext Transfer Protocol)
- C
FTP (File Transfer Protocol)
- D
IP (Internet Protocol)
Detailed Technical Solution & Explanation
The Transmission Control Protocol (TCP) is the connection-oriented transport layer protocol responsible for controlling end-to-end data transfer. It provides comprehensive flow control (via sliding window advertising) and congestion control (Slow Start, Congestion Avoidance, Fast Retransmit/Recovery).
Option Analysis:
•
Option A (TCP): Correct; transport protocol providing flow and congestion control during data transmission.
•
Option B (HTTP): Application-layer request/response protocol running on top of TCP.
•
Option C (FTP): Application-layer file transfer protocol running on top of TCP.
•
Option D (IP): Network-layer protocol providing best-effort packet routing without flow control.
