Zorluk: OrtaTCP vs UDP Comparison and Protocols

A network engineer inspects packet captures from a server connection and notes a transport layer header size of 20 bytes featuring Sequence Number and Window Size fields. Which statement correctly identifies the transport protocol in use and its operational trade-off relative to UDP?

  1. The packet uses TCP, which provides reliable connection-oriented delivery and flow control but incurs higher header overhead and processing delay than UDP.Cevap
  2. B
    The packet uses UDP, which provides reliable delivery by adjusting the Window Size field dynamically to prevent network congestion.
  3. C
    The packet uses TCP, which operates statelessly with a fixed 8-byte header to minimize transmission latency across WAN links.
  4. D
    The packet uses UDP, which uses a 20-byte header to perform sequence tracking while maintaining lightweight, connectionless operations.

Cevap

The packet uses TCP, which provides reliable connection-oriented delivery and flow control but incurs higher header overhead and processing delay than UDP.
The presence of a 20-byte header along with Sequence Number and Window Size fields indicates the Transmission Control Protocol (TCP). TCP is connection-oriented and stateful, providing retransmission, sequencing, and flow control. The trade-off for these features is higher header overhead (20 bytes minimum compared to UDP's fixed 8 bytes) and additional latency required for state tracking.

Adım Adım Çözüm

1
Analyze the header characteristics in the packet capture.
Identified a 20-byte transport header with Sequence Number and Window Size fields.
These fields and the 20-byte minimum size specifically belong to the TCP header; UDP headers are fixed at 8 bytes.
2
Evaluate protocol operational mechanics and trade-offs.
TCP provides stateful, reliable connection management and windowing-based flow control at the cost of higher overhead.
The extra header fields (20 bytes vs UDP's 8 bytes) and acknowledgment mechanisms guarantee in-order delivery but introduce latency and bandwidth overhead.
