Packet delay variation — In computer networking, packet delay variation (PDV) is the difference in end to end delay between selected packets in a flow with any lost packets being ignored (RFC 3393).[1] The effect is sometimes referred to as jitter, although the… … Wikipedia
Delay-tolerant networking — (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme… … Wikipedia

Group delay and phase delay — Group delay is a measure of the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay is a similar measure of the time… … Wikipedia
Darwin from Orchids to Variation — The life and work of Charles Darwin from the publication of Orchids to the publication of Variation during the years between 1860 and 1868 continued with Darwin carrying out his research and experimentation on evolution as he worked sporadically… … Wikipedia
Constitutional growth delay — (CGD) is a term describing a temporary delay in the skeletal growth and thus height of a child with no other physical abnormalities causing the delay. Short stature may be the result of a growth pattern inherited from a parent (familial) or occur … Wikipedia
Jitter — For other meanings of this word, see Jitter (disambiguation). 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… … Wikipedia
TDMoIP — In computer networking and telecommunications, TDM over IP (TDMoIP) is the emulation of time division multiplexing (TDM) over a packet switched network (PSN). By TDM we mean a T1, E1, T3, or E3 signal, while the PSN is based either on IP or MPLS… … Wikipedia
Professional video over IP — systems use some existing standard video codec to reduce the program material to a bitstream (such as an MPEG 2 transport stream), and then to use an Internet Protocol (IP) network to carry that bitstream encapsulated in a stream of IP packets.… … Wikipedia
