CS402: Computer Communications and Networks

Watch this video on TCP and reliable data delivery. Why does TCP divide a file into packets, and how do sequence numbers aid in reconstruction at the destination? Consider TCP's response to packet loss and the role of acknowledgments in ensuring complete data transfer. How does TCP determine when to resend packets, and how does the timeout mechanism deal with delayed or out-of-order packets? Each element of TCP's design is essential for the protocol's ability to deliver data reliably over the Internet.
