An application developer is configuring a telemetry collection service across a branch network. The service requires low transmission latency and minimal protocol processing overhead for periodic 50-byte metric updates. The developer selects User Datagram Protocol (UDP) instead of Transmission Control Protocol (TCP). Which characteristic of UDP directly accounts for its lower protocol overhead compared to TCP?
- UDP utilizes a fixed 8-byte header structure without connection establishment states or sequence tracking mechanisms.Answer
- BUDP incorporates dynamic window size fields to continuously optimize throughput based on receiver buffer capacity.
- CUDP reduces transmission delay by maintaining a 20-byte header that relies on cumulative acknowledgments.
- DUDP relies on hardware-level sequence numbers to reorder out-of-sequence datagrams without software intervention.
Answer
UDP utilizes a fixed 8-byte header structure without connection establishment states or sequence tracking mechanisms.
UDP reduces protocol overhead because its header is fixed at 8 bytes (containing only Source Port, Destination Port, Length, and Checksum) and it operates without connection setup (handshake), sequencing, or flow control state tracking.
