Zorluk: KolayNetwork Performance Monitoring and Metrics

During a network performance check of a real-time audio application, an administrator notices that speech quality degrades due to irregular delivery times of audio packets. Which network performance metric specifically measures this variation in packet arrival times?

  1. JitterCevap
  2. B
    Bandwidth
  3. C
    Port Mirroring
  4. D
    Duplex Mismatch

Cevap

Jitter is the specific metric measuring packet arrival delay variation.
Jitter quantifies the variance in delay between received packets. In real-time audio transmissions, inconsistent delay causes buffer underflows or frame drops, leading to distorted sound.

Adım Adım Çözüm

1
Identify the symptom described in the scenario
The issue involves irregular arrival times and delay variation of real-time audio packets.
Real-time applications like VoIP require consistent packet timing to reconstruct stream data smoothly.
2
Match the symptom to the corresponding performance metric
Jitter (packet delay variation) quantifies the fluctuation in latency between consecutive packets.
By definition, jitter measures arrival timing consistency across a network path.
