Many multimedia applications, including audio and video, require quality of service( QOS) guarantees from network. A typical user is only concerned with the QOS requirements on end -to-end basis and does not care about the local switching node QOS. In this paper, we propose a general framework to map the end-to-end QOS requirement into the local switching node QOS requirements. Most of recent r...

Providing a photonic alternative to the current electronic switching in the backbone, optical packet switching (OPS) and optical burst switching (OBS) require optical buffering. Optical buffering exploits delays in long optical fibers; an optical buffer is implemented by routing packets through a set of fiber delay lines (FDLs). Previous studies pointed out that, in comparison with electronic b...

A delay is known to induce multistability in periodic systems. Under influence of noise, coupled oscillators can switch between coexistent orbits with different frequencies and different oscillation patterns. For coupled phase oscillators we reduce the delay system to a nondelayed Langevin equation, which allows us to analytically compute the distribution of frequencies and their corresponding ...

• NMP: Networked Music Performance • Ultra-low delay variant of conferencing • End-to-end delays of 25 rather than 150 ms • NMP is not the same as conferencing • Participants prefer to do their own mixing • The MCU should only relay data streams • The MusiNet project • Ultra-low delay audio and video coding • Each participant indicates what it wants to receive • The MCU maintains a stream routi...

This study aims to determine whether audit opinion, public accounting firm reputation, delay, and financial distress as moderating variables have an influence on auditor switching. The data used are companies in the manufacturing sector listed Indonesia Stock Exchange (IDX) 2018-2020. obtained form of statements, sample selection process is carried out using purposive sampling, hypothesis testi...

Contemporary Voice-Over-IP (VoIP) systems typically negotiate only one codec for the entire VoIP session life time. However, as different codecs perform differently well under certain network conditions like delay, jitter or packet loss, this can lead to a reduction of quality if those conditions change during the call. This paper makes two core contributions: First, we compare the speech quali...

625 Abstract— Dynamic sensor network(DSN) technology which is based on swarming flight type air node offers analyzed and acquired information on target data gathered by air nodes in rotation flight or 3 dimension array flight. Efficient operation of dynamic sensor network based on air node is possible when problems of processing time, data transmission reliability, power consumption and intermi...

In the Internet, because of huge scale and distributed administration, it is of practical importance to infer network-internal characteristics that cannot be measured directly. In this paper, we propose a general method of determining characteristics of links from given characteristics of end-to-end paths. Our method can be applied to an arbitrary path-topology. Furthermore we show the general ...

A new clock-feedthrough compensation scheme for switchedcurrent circuits is proposed. The scheme is especially suited for the design of delay lines for high-frequency operation. The circuit operates by using an improved two-step technique, in which the input is sampled in a parallel combination of a coarse and a fine memory transistor. Since both transistors are of the same type, large switchin...
