  2. Bufferbloat - Wikipedia

    en.wikipedia.org/wiki/Bufferbloat

    Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high-speed networks can become practically unusable for many interactive applications like voice over IP (VoIP), audio streaming , online ...

  3. Jitter - Wikipedia

    en.wikipedia.org/wiki/Jitter

    Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristic that varies regularly with time. Jitter frequency, the more commonly quoted figure, is its inverse. ITU-T G.810 classifies deviation lower frequencies below 10 Hz as wander and higher frequencies at or above 10 Hz as jitter. [2]

  4. Packet delay variation - Wikipedia

    en.wikipedia.org/wiki/Packet_delay_variation

    Instantaneous packet delay variation is the difference between successive packets—here RFC 3393 does specify the selection criteria—and this is usually what is loosely termed "jitter", although jitter is also sometimes the term used for the variance of the packet delay. As an example, say packets are transmitted every 20 ms.

  5. Network performance - Wikipedia

    en.wikipedia.org/wiki/Network_performance

    Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude , or phase of periodic signals.

  6. Quality of service - Wikipedia

    en.wikipedia.org/wiki/Quality_of_service

    Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network.

  7. Wow and flutter measurement - Wikipedia

    en.wikipedia.org/wiki/Wow_and_flutter_measurement

    This measurement quantifies the amount of 'frequency wobble' (caused by speed fluctuations) present in subjectively valid terms. Turntables tend to suffer mainly slow wow. In digital systems, which are locked to crystal oscillators, variations in clock timing are referred to as wander or jitter, depending on speed.

  8. Micro stuttering - Wikipedia

    A depiction of 5 display refresh cycles with what may be shown during a micro stuttering case. Each colored section represents one of the GPU's frame buffer and each color change represents a frame buffer swap.

  9. UPC and NPC - Wikipedia

    en.wikipedia.org/wiki/UPC_and_NPC

    Cells that fail to conform, i.e. because they come too soon after the preceding cell on the channel or path because the average rate is too high or because the jitter exceeds the tolerance, may be dropped, i.e. discarded, or reduced in priority so that they may be discarded downstream if there is congestion.
