Networked devices are often equipped with multiple interfaces. Legacy routing and transport protocols only support the transport of data over a single interface resp. paths. This tutorial discusses extensions for IP and TCP in order to support multiple interfaces. Multihoming and mobility management allow the simultaneous usage of interfaces by independent application data flows, while multipath transport...
AODV uses the minimum hop count as the connection metric do decide which route out of a set of possible routes should be selected to send a packet from a source to a destination. This metric can however be misleading if a route with a small number of hop counts is congested and interfered by neighbouring stations so that in this case another route could be faster despite of a higher hop count which...
The aim of this paper is to address one aspect of this challenge - how do we build affordable communication networks in developing regions by adapting technologies originally designed for the industrialized world to be appropriate and sustainable in the developing world environments It is in this context that the role of information and communication technologies (or ICTs) in development has been...
We present the design and implementation of ENDEAVOUR - a framework for integrated end-to-end disaster recovery (DR) planning. Unlike existing research that provides DR planning within a single layer of the IT stack (e.g. storage controller based replication), ENDEAVOUR can choose technologies and composition of technologies across multiple layers like virtual machines, databases and storage controllers...
We introduce the coupled placement problem for modern data centers spanning placement of application computation and data among available server and storage resources. While the two have traditionally been addressed independently in data centers, two modern trends make it beneficial to consider them together in a coupled manner: (a) rise in virtualization technologies, which enable applications packaged...
In this paper, we present a novel, high throughput field-programmable gate array (FPGA) architecture, PITIA, which combines the high-performance of application specific integrated circuits (ASICs) and the flexibility afforded by the reconfigurability of FPGAs. The new architecture, which targets datapath circuits, uses the concepts of wave steering and pipelined interconnects. We discuss the FPGA...
