The ability to capture and process packet-level data is of intrinsic importance in network testbeds that offer broad experimental capabilities to researchers. In this paper we describe the design and implementation of a passive measurement system for network testbeds called GIMS. The system enables users to specify and centrally manage packet capture on a set of dedicated measurement nodes depl...

New generation passive optical network aims at providing more than 100 Gb/s capacity. Thanks to recent progress enabling a variety of optical transceivers up to 40 Gb/s, many evolution possibilities to 200G PONs (passive optical network) could be investigated. This work proposes two directly deployable cases of evolution to 200G PON based on the combination of these improved optical transceiver...

Distributed applications require timely network measurements so that they can adapt to changing network conditions and make efficient use of grid resources. One of the key issues in obtaining network measurements is the intrusiveness of the measurements themselves—how much network performance is “wasted” taking the measurements? Our goal is to combine active and passive monitoring techniques to...

In this paper two R‑L network simulator configurations employing a single VDDIBA, one resistance and one grounded capacitance are presented. The first configuration is a grounded series resistor-inductor (R‑L) network simulator and the second configuration is intended for grounded parallel resister-inductor (R‑L) circuit simulation. Both the proposed circuits enjoy several beneficial features s...

The purpose of this paper is to compare the performance of four passive optical network topologies in implementing multi-user quantum key distribution, using 3 protocols proposed by quantum cryptography (B92, EPR, and SSP). The considered networks are the passive-star network, the optical-ring network based on the Signac interferometer, the wavelength-routed network, and the wavelength-addresse...

This paper is based on the EL mathematical model of the MMC synchronous rotating coordinate system, derived the MMC passive control law, the inner ring current passive controller is designed and the AC voltage controller is set. In order to restrain the negative sequence current caused by the network voltage unbalance or asymmetric AC system fault, the positive and negative sequence of independ...

This paper provides a passivity based framework to synthesise l 2 -stable digital control networks in which m strictly-output passive controllers can control n−m strictly-output passive plants. The communication between the plants and controllers can tolerate time varying delay and data dropouts. In particular, we introduce a power-junction-network, a general class of input-output-wave-variable...
