A network technician is deploying a real-time IP surveillance camera system on a local network. The video application requires immediate frame delivery for live monitoring and can tolerate minor frame loss, but cannot tolerate latency or buffering caused by frame retransmissions. Which transport layer protocol best satisfies these application requirements, and why?
- UDP, because it is a connectionless protocol that transmits datagrams without establishing a session or waiting for acknowledgments, reducing delivery latency.Cevap
- BTCP, because it is a connection-oriented protocol that uses a three-way handshake to guarantee missing video frames are retransmitted immediately.
- CUDP, because it operates at the Network layer to encapsulate IP packets directly without transport layer overhead.
- DTCP, because it utilizes port 69 to establish connectionless streaming channels with minimal header overhead.
Cevap
UDP should be selected because it is a connectionless protocol that transmits datagrams without session setup or retransmission delay, fulfilling the low-latency requirement of real-time video streaming.
UDP (User Datagram Protocol) is a connectionless transport protocol that sends data without establishing a formal connection or tracking packet delivery. Because it omits handshakes, flow control, and packet retransmissions, it achieves the minimal latency necessary for live, real-time video streaming applications.
