Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
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.
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]
In order to avoid the thundering herd problem, jitter can be purposefully introduced in order to break the synchronization across the clients, thereby avoiding collisions. In this approach, randomness is added to the wait intervals between retries, so that clients are no longer synchronized.
The "jitter" is a 2D offset that shifts the pixel grid, and its X and Y magnitude are between 0 and 1. [ 2 ] [ 3 ] When combining pixels sampled in past frames with pixels sampled in the current frame, care needs to be taken to avoid blending pixels that contain different objects, which would produce ghosting or motion-blurring artifacts.
They can also affect the jitter in the interrupt latency, which can drastically affect the real-time schedulability of the system. The Intel APIC architecture is well known for producing a huge amount of interrupt latency jitter. [citation needed] Maximum interrupt latency is largely determined by the methods an OS uses for interrupt handling.
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.
Jitter is often measured as a fraction of UI. For example, jitter of 0.01 UI is jitter that moves a signal edge by 1% of the UI duration. The widespread use of UI in jitter measurements comes from the need to apply the same requirements or results to cases of different symbol rates. This can be d
