In this paper we will discuss avenues to exploit the potential low loss and low linearity of hollow core photonic band gap fibres (HC-PBGF) at 2 microns wavelength. In particular, we will show recent developments in semiconductor devices to enable a 100Gbit/s transmission demonstration.
We describe a scheduler based on deficit-round robin (DRR) for multiple servers of multiple packet-flows, where each packet-flow may be served by only a subset of available (preferred) servers. The scheduler uses a token allocation algorithm that is weighted max-min fair, and so we've called it Multi-Server Max-min Fair DRR (MSMF-DRR). The scheduler also compensates for potential errors in estimates...
We present BTLab, a distributed platform to measure and analyze the differences between BitTorrent clients. Due to extensibility, and a certain vagueness in the BitTorrent specification, many clients diverge in some aspects from each other. Most research to date disregarded the effects of these differences. BTLab allows us to create and control BitTorrent swarms, composed of hundreds of clients of...
ErAs:In0.53Ga0.47As superlattice THz emitters are fabricated and characterized at an excitation wavelength of 1.55 μm. Photocurrent-voltage characteristics, carrier lifetimes and bandwidth of the THz output are discussed as a function of the superlattice period.
Vehicle-to-Vehicle and Vehicle-to-Roadside communications are going to become an indispensable part of the modern day automotive experience. For people on the move, vehicular networks can provide critical network connectivity and access to real-time information. Infestations play a vital role in these networks by acting as gateways to the Internet and by extending network connectivity. In this context,...
