Active Knowledge Engineering Lab The Active Knowledge Engineering Lab activities include investigations that are about discovering, externalizing, expressing, representing, sharing, exploring, configuring, activating, growing and managing enterprise knowledge as well as designing new programming platforms based on mentioned above principles. This year we have been focused on the following topic...

Mission critical manufactory and enterprise IT infrastructure and on-line Internet services require 24x7 availability and usually have an agreed Service Level Agreements (SLA) around its services offering. Currently, most enterprise and manufactory IT datacenters experience severe problems managing the large N tier, networked environments that these mission critical systems run on. Most of thes...

Interoperability of heterogeneous networked systems has yet to reach the maturity required by ubiquitous computing due to the technology-dependent nature of solutions. The Connect Integrated Project attempts to develop a novel network infrastructure to allow heterogeneous networked systems to freely communicate with one another by synthesising the required connectors on-the-fly. A key objective...

Concurrent and distributed computing, using portable software systems or environments on general purpose networked computing platforms, has recently gained widespread attention. Many such systems have been developed, and several are in production use. This paper describes the evolution of the PVM system, a software infrastructure for concurrent computing in networked environments. PVM has evolv...

The U.S. infrastructure is a trillion dollar investment, defined broadly to include road systems and bridges, water distribution systems, water treatment plants, power distribution systems, telecommunication network systems, commercial and industrial facilities, etc. In spite of the enormous investments made in these systems and their importance to the US economy, we (as in government, industry...

Peer-to-Peer (P2P) systems are application layer networks which enable networked hosts to share resources in a distributed manner. An important problem in such networks is to be able to efficiently search the contents of other peers. In this paper we present a survey of search techniques for information retrieval in P2P networks, including recent techniques proposed by the authors. We also pres...

As the Internet has grown, and as systems and networked services within enterprises have become more pervasive, many services with high availability requirements have emerged. These requirements have increased the demands on the reliability of the infrastructure on which those services rely. Various techniques have been employed to increase the availability of services deployed on the Internet....

In recent years, many research efforts have focused on building experimentation platforms where structural changes to future Internet can be implemented and tested. GENI, instantiated by its prototype implementations, e.g. ProtoGENI, is a notable example of such systems. In this document, we present the PrimoGENI approach; which aims to augment the GENI suite of interoperable infrastructure to ...
