Service Science, Management, and Engineering (SSME) is a term introduced by IBM to describe the science of services, a new interdisciplinary approach to the study, design, and implementation of services systems. The goal of this new discipline is to bring analytical rigor to key issues as service creation and delivery. This new discipline is still at its infancy and it is expected that its development will accelerate in the next five years. In this talk, I will give an overview of this new discipline with an emphasis on IT and networking services. First, I will give a definition of services, describe its main characteristics, and discuss a framework for implementing services. Then, I will discuss two examples: Service oriented architectures and the Next Generation Networks, and present some current research.

The goal of this presentation is to present a new concept and the results of an implement of a Post-IP architecture. This post-IP architecture is mainly based on virtual networking with a piloting system able to optimise 1) the placement of virtual machines of a new virtual network, and 2) the urbanisation of virtual machines implemented on the physical network equipment. This architecture is intelligence-oriented using mechanisms capable of controlling automatically the placement of all virtual machines in the physical network. In this presentation, we will describe how to create and delete virtual networks on the fly. Indeed, the system is able to create a new network with all kinds of equipment (e.g., virtual node-B, virtual access points, virtual routers, virtual LSRs, virtual firewall, virtual SIP-based servers, virtual devices, and so on). A GUI is providing the facility to deploy instantaneously a virtual network and to remove it if necessary. However, the real difficulty when deploying a new virtual network is to be able to prove that the resources that are allocated to this new network are sufficient so that the necessary QoS can be guaranteed. This is where urbanisation of the virtual machines is used. By urbanisation we mean how to place different virtual machines in the physical network

During the last 12 years a telemetric network is operated in Greece, measuring the electromagnetic field variations (EMV) at low and high frequencies. In each field station, we measure using tuned loop antennas, the two horizontal components of the electromagnetic field variations, in low frequencies (LF), i.e in 3 and 10 kHz. Using λ/2 dipoles we measure also high frequencies (HF), i.e in 41 and 46 MHz. The developed technology of the field stations is based on a datalogger, which digitizes and stores the information. This EMV network has 11 digital field stations spreaded almost in all over Greece, uses the already existing field facilities of the National Seismological Network of the Geodynamic Institute, of National Observatory of Athens (NOA). The communication of the field stations is based on a real time telemetry using the leased telephone lines of the new digital telemetric system of N.O.A. By using multiplexing technique, the seismological data are transferred in real time, and at the same time seven others information streams from seven other projects, are collected. One of the latter projects is that measures the electromagnetic variation (EMV) project. Another one field station in Zante Island belong to University of Athens, is acting as EMV prototype field station and records UHF , VHF and ULF components of electromagnetic variation. All the telemetric system has been designed to work unattended.
