In this paper we present an analysis of over 236,000 file transfers between 10 widely distributed Internet hosts. The goal of this work is to broaden the understanding of how network path and congestion properties contribute to delays in TCP file transfers. The first part of our analysis investigates how end-to-end path properties (eg. physical distance, router hops, autonomous system hops, or ...

Bandwidth continues to be a problem for the active enterprise. One solution to bandwidth problems over long-haul distances with restricted bandwidth is the Wide Area Network (WAN) Accelerator. This accelerator works by tokenizing blocks of information that are sent multiple times in network traffic. Because many such communications include previously transmitted material, the accelerator traffi...

Abstract Influenced by the continuous growth of renewable energy installation scale and increasingly prominent characteristics AC/DC hybrid structure, disturbance behavior large power grid is becoming more complex. To ensure safety grid, higher requirements are put forward for reliability, accuracy orderliness out-of-step splitting control which belonged to third line defense. Firstly, this pap...

This paper proposes a novel online measurement-based Wide-Area Voltage Control (WAVC) method using Phasor Measurement Unit (PMU) data in power systems with Flexible AC Transmission System (FACTS) devices. As opposed to previous WAVC methods, the proposed does not require any model knowledge or participation of all buses and considers both active reactive perturbations. Specifically, exploits re...

in this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. this technique uses synchronized phasors measured by phasor measurement units (pmus) in a wide-area measurement system. in order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...
