Because Arya Stark 's direwolf, Nymeria, attacks Prince Joffrey Baratheon along the banks of the Trident, Nymeria is ordered to be killed but she cannot be found.
In the context of computer networks, jitter is the variation in latency as measured in the variability over time of the packet latency across a network. A network with constant latency has no variation (or jitter). Packet jitter is expressed as an average of the deviation from the network mean latency. However, for this use, the term is imprecise.
Packet jitter is expressed as an average of the deviation from the network mean latency. However, for this use, the term is imprecise. The standards-based term is  packet delay variation  (PDV).PDV is an important quality of service factor in assessment of network performance.eterministic jitter is a type of clock timing jitter or data signal jitter that is predictable and reproducible. The peak-to-peak value of this jitter is bounded, and the bounds can easily be observed and predicted.
