    Telecommunication infrastructures play a vital role in modern society. The advancements in the range of network service offerings, their performance, quality of service, security, and ubiquity are relentless, despite global economy fluctuations. The demand for high bandwidth network infrastructures is continuously growing within both academic and industrial sectors. Grid computing is one of the many examples of the new emerging paradigm of networking characterized by huge data traffic flows, that require an extremely high-performance network infrastructure. The need of high speed is emerging also in mobile, wireless network environments, where new wireless technologies promise data rates above 100 Mbps. Other high bandwidth network examples include community access networks, on demand optical networks and the Next Generation Internet.

    • Virtual distributed testbed for optimisation and coexistence of heterogeneous systems

      Research Article in 2nd International IEEE/Create-Net Conference on Testbeds and Research Infrastructures for the Development of Networks and Communities

      Jonathan Rodriguez, A. Gameiro, C. Politis, G. Kormentzas, Nicolas Ibrahim

The achievement of this vision raises significant research challenges in view of system coexistence, system scale, interoperability, and evaluation tool design to provide a framework for cost-effective assessment of optimisation algorithms within a heterogeneous system environment. The UNITE (virtual distributed testbed for optimisation and coexistence of heterogeneous systems) platform aims to address the aforementioned research challenges by implementing an efficient, accurate and scalable virtual distributed testbed to support cross-system, and cross-layer optimization of heterogeneous systems in a unified manner. Through the use of the virtual testbed, cross-layer and cross-system interactions between next generation wireless systems and protocols can be investigated, without neglecting important real-system details.

It is an integrated testbed for applications and advanced network services, organised as a consortium with partners from industry, research laboratories, universities and the DFN association. Major goals are the test of different signalling mechanisms in a heterogeneous environment of routers and switches and the development of a user-driven dynamical bandwidth allocation

    • Adaptive MPLS load sharing: modeling, dimensioning and test-bed platform

In MPLS enabled networks, label switched paths (LSPs) are established and released using a variety of signaling protocols and data packets are forwarded over LSPs using the label swapping paradigm. Load sharing has been identified as an attractive mechanism to perform traffic engineering in MPLS networks. Due to the connection oriented nature of MPLS, arbitrary load sharing schemes may be deployed, without the inherent limitations of load sharing enabled IP routing protocols. The objective of this paper is the following: based on and starting from analytical studies aimed at obtaining engineering rules and guidelines to dimension and to optimize MPLS load sharing when taking into account the statistical properties of the traffic, we present a test-bed platform that offers a generic framework to asses the applicability and to evaluate the performance of diverse MPLS load sharing schemes, focusing on an adaptive measurement-based ones. We detail the functional architecture of the platform, its design and implementation and we showcase its use in simple but meaningful scenarios

This paper describes the groundwork for the development of such network in terms of its requirements, functionalities, provided services, enabled researches and design concepts. Structurally, the Kyatera network is composed of three sub-networks that will enable parallel experiments and research to be carried out in optical, networking and applications domains. Given the services and the technologies deployed, it will promote the development of joint experiments with peer advanced research centers both national and international

Each node in the testbed consists of a "single-board computer", namely Crossbow's Stargate, equipped with a wireless network card and a Webcam. We assess energy consumption of activities representative of the target application (e.g., perimeter surveillance) using a benchmark that runs (individual and combinations of) "basic" tasks such as processing, flash memory access, image acquisition, and communication over the network. In our characterization, we consider the various hardware states the system switches through as it executes these benchmarks, e.g., different radio modes (sleep, idle, transmission, reception), and Webcam modes (off, on, and acquiring image). We report both steady-state and transient energy consumption behavior obtained by direct measurements of current with a digital multimeter. We validate our measurements against results obtained using the Stargate's on-board energy consumption measuring capabilities
