Wide-Area Traffic: The Failure of Poisson Modeling

by Vern Paxson, Sally Floyd - IEEE/ACM TRANSACTIONS ON NETWORKING , 1995
"... Network arrivals are often modeled as Poisson processes for analytic simplicity, even though a number of traffic studies have shown that packet interarrivals are not exponentially distributed. We evaluate 24 wide-area traces, investigating a number of wide-area TCP arrival processes (session and con ..."

time scales; and that FTP data connection arrivals within FTP sessions come bunched into “connection bursts,” the largest of which are so large that they completely dominate FTP data traffic. Finally, we offer some results regarding how our findings relate to the possible self-similarity of widearea

Random Early Detection Gateways for Congestion Avoidance.

by Sally Floyd , Van Jacobson - IEEELACM Transactions on Networking, , 1993
"... Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving at the gatewa ..."

allowing occasional bursts of packets in the queue. During congestion, the probability that the gateway notifies a particular connection to reduce its window is roughly proportional to that connection's share of the bandwidth through the gateway. RED gateways are designed to accompany a transport

Packet Switching in Radio Channels: Part I -- Carrier sense multiple-access modes and their throughput-delay characteristics

by Leonard Kleinrock, Fouad A. Tobagi , 1975
"... Radio communication is considered as a method for providing remote terminal access to computers. Digital byte streams from each terminal are partitioned into packets (blocks) and transmitted in a burst mode over a shared radio channel. When many terminals operate in this fashion, transmissions may c ..."

Packet Loss Correlation in the MBone Multicast Network

by Maya Yajnik , Jim Kurose, Don Towsley , 1996
"... The recent success of multicast applications such as Internet teleconferencing illustrates the tremendous potential of applications built upon wide-area multicast communication services. A critical issue for such multicast applications and the higher layer protocols required to support them is the m ..."

is the manner in which packet losses occur within the multicast network. In this paper we present and analyze packet loss data collected on multicast-capable hosts at 17 geographically distinct locations in Europe and the US and connected via the MBone. We experimentally and quantitatively examine the spatial

The Supernova Gamma-Ray Burst Connection

by S. E. Woosley, J. S. Bloom , 2006
"... ABSTRACT: Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously with core-collapse supernovae (SNe), thus linking by a common thread nature’s two grandest explosions. We review here the growing evidence for and theoretical implications of this association, and conclude t ..."

Just-In-Time Signaling for WDM Optical Burst Switching Networks

by John Y. Wei, Ray I. McFarland, Jr. - Journal of Lightwave Technology , 2000
"... We describe the architecture, design, and implementation of a novel just-in-time (JIT) signaling protocol for optical burst switching (OBS) in wavelength division multiplexed (WDM) optical networks. The JIT-OBS paradigm is designed for ultra-low-latency unidirectional transport of data-bursts across ..."

across an optical network. It combines the desirable features of circuit-switching and packet-switching. It features out-of-band control signal processing that eliminates buffering of data-burst at intermediate nodes, while minimizing the setup time, and maximizing the cross-connect bandwidth efficiency

The supernova-gamma ray burst connection

by J. Craig Wheeler, Peter Höflich, Lifan Wang - ApJ , 1998
"... ABSTRACT. Study of the polarization of supernovae has suggested that the core collapse process may be intrinsically strongly asymmetric. There is a tentative trend for supernova with smaller envelopes showing more polarization, with SN Ic having the smallest envelopes and showing the largest polariz ..."

polarization. The recent discovery of the unusual supernova SN 1998bw and its apparent correlation with the gamma-ray burst GRB 980425 has raised new issues concerning both the γ-ray bursts and supernovae. SN 1998bw resembled a SN Ic, but was unusually bright at maximum light in the optical and radio, and its

An introduction to optical burst switching

by Tzvetelina Battestilli, Harry Perros , 2003
"... Optical burst switching is a promising solution for all-opti-cal WDM networks. It combines the benefits of optical packet switching and wavelength routing while taking into account the limitations of the current all-optical technology. In OBS, the user data is collected at the edge of the network, s ..."

Emergence of Bursting Activity in Connected Neuronal Sub-Populations

by Marta Bisio, Ro Bosca, Valentina Pasquale, Luca Berdondini , 2014
"... Uniform and modular primary hippocampal cultures from embryonic rats were grown on commercially available micro-electrode arrays to investigate network activity with respect to development and integration of different neuronal populations. Modular networks consisting of two confined active and inter ..."

and inter-connected sub-populations of neurons were realized by means of bi-compartmental polydimethylsiloxane structures. Spontaneous activity in both uniform and modular cultures was periodically monitored, from three up to eight weeks after plating. Compared to uniform cultures and despite lower cellular

Gravitational wave: gamma-ray burst connections

by Jim Hough , 2007
"... After 35 years of experimental research, we are rapidly approaching the point at which gravitational waves (GWs) from astrophysical sources may be directly detected by the long-baseline detectors LIGO (USA), GEO 600 (Germany/UK), VIRGO (Italy/France) and TAMA 300 (Japan), which are now in or coming ..."

In this paper, a brief review of the state of the art in detector development and exploitation will be given, with particular relevance to a
