One of the researchers who contributed to the Internet as it was being formed in the late 1970s and 1980s, he was a member of the Internet Architecture Board, the group responsible for guiding the Internet's development. He was also chairman of the CSNET technical committee, a member of the CSNET executive committee, and chairman of DARPA's Distributed Systems Architecture Board. Comer has consulted for industry on the design of computer networks. In addition to giving talks in US universities, each year Comer lectures to academics and networking professionals around the world. Comer's operating system, XINU, and implementation of TCP/IP protocols (both documented in his textbooks), have been used in commercial products. Comer is a Distinguished Professor of Computer Science at Purdue University. He is currently on leave from Purdue, serving as VP of Research Collaboration at Cisco Systems.

Recently, Comer has taught courses on networking, internetworking, computer architecture, and operating systems. He has developed innovative labs that provide students with the opportunity to gain hands-on experience with operating systems, networks, and protocols. In addition to writing a series of best-selling technical books that have been translated into 16 languages, he served as the North American editor of the journal Software — Practice and Experience for 20 years. Comer is a fellow of the ACM.

Jitter is a significant, and usually undesired, factor in the design of almost all communications links. Jitter can be quantified in the same terms as all time-varying signals, e.g., (RMS), or peak-to-peak displacement. Also like other time-varying signals, jitter can be expressed in terms of.

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.

Computer Network

G.810 classifies jitter frequencies below 10 Hz as wander and frequencies at or above 10 Hz as jitter. Jitter may be caused by and with carriers of other signals. Jitter can cause a display monitor to flicker, affect the performance of processors in personal computers, introduce clicks or other undesired effects in audio signals, and cause loss of transmitted data between network devices. The amount of tolerable jitter depends on the affected application. Contents. Jitter metrics For jitter, there are three commonly used metrics: Absolute jitter The in the position of a clock's edge from where it would ideally be. Period jitter (aka cycle jitter) The difference between any one clock period and the ideal or average clock period.

Period jitter tends to be important in synchronous circuitry such as digital state machines where the error-free operation of the circuitry is limited by the shortest possible clock period (average period less maximum cycle jitter), and the performance of the circuitry is set by the average clock period. Hence, synchronous circuitry benefits from minimizing period jitter, so that the shortest clock period approaches the average clock period. Cycle-to-cycle jitter The difference in duration of any two adjacent clock periods. It can be important for some types of clock generation circuitry used in and interfaces. In, the unit used for the above types of jitter is usually the (UI) which quantifies the jitter in terms of a fraction of the transmission unit period.

This unit is useful because it scales with clock frequency and thus allows relatively slow interconnects such as to be compared to higher-speed internet backbone links such as. Absolute units such as picoseconds are more common in microprocessor applications. Units of degrees and radians are also used. In the normal distribution one from the (dark blue) accounts for about 68% of the set, while two standard deviations from the mean (medium and dark blue) account for about 95% and three standard deviations (light, medium, and dark blue) account for about 99.7%. If jitter has a, it is usually quantified using the of this distribution (which translates to a RMS measurement for a zero-mean distribution). Often, jitter distribution is significantly non-Gaussian.

This can occur if the jitter is caused by external sources such as power supply noise. In these cases, peak-to-peak measurements are more useful. Many efforts have been made to meaningfully quantify distributions that are neither Gaussian nor have meaningful peaks (which is the case in all real jitter). All have shortcomings but most tend to be good enough for the purposes of engineering work.

Note that typically, the reference point for jitter is defined such that the jitter is 0. In, in particular such as the, jitter can refer to the variation in the delay of the. Types One of the main differences between random and deterministic jitter is that deterministic jitter is bounded and random jitter can be unbounded in some circumstances. Random jitter Random Jitter, also called Gaussian jitter, is unpredictable electronic timing noise. Random jitter typically follows a or Normal distribution. It usually follows this pattern because most noise or jitter in an is caused by, which has a Gaussian distribution.

Another reason for random jitter to have a distribution like this is due to the. The central limit theorem states that composite effect of many uncorrelated noise sources, regardless of the distributions, approaches a Gaussian distribution. Deterministic jitter is a type of 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. Deterministic jitter can either be correlated to the data stream or uncorrelated to the data stream (bounded uncorrelated jitter). Examples ofMinimizing the effects of sampling jitters in wireless sensors networks'.

Decomposition Jitter signal can be decomposed into (IMFs), which can be further applied for filtering or dejittering. See also. References.
