The demonstration shows how to do grid computing using the GILDA dissemination grid testbed and the GENIUS grid portal, developed by INFN and NICE srl in the context of both the Italian INFN Grid Project and the European EGEE Project. During the demo, job submission, data management, and grid monitoring will be shown as well as how to join the GILDA testbed to test users' own applications.

ORBIT is an open, large-scale wireless network testbed which facilitates a broad range of experimental research on next-generation protocols and application concepts. ORBIT is designed to achieve reproducibility of experimentation, while also supporting evaluation of protocols and applications in real-world settings.
The laboratory-based wireless network emulator uses a novel approach involving a large two-dimensional grid of 400 802.11x radio nodes which can be dynamically interconnected into specified topologies with reproducible wireless channel models.
During the demonstration we will show how to define, schedule, run, and analyze experiments on this testbed through its web portal.

MIPSD (Mobility-oriented IPSec Daemon):

a tool for integrated Mobility and Security support in the Ecumene network

The IP protocol is stateless and connectionless, hence cannot guarantee a secure delivery of the information. To overcome this limitation and offer a stateful security, IPSec introduces logical connections between two peers, indicated as Security Associations (SA), able to provide security services to the traffic which flows through them. The management of IPSec SA, which includes creation, activation, destruction of entries, can be performed manually by an operator, but it is often delegated to ISAKMP and IKE protocols, due to the overwhelming complexity of such approach, which raises obvious scalability problems. However, the IPv6 address of each peer must be known in advance to the other one in order for the ISAKMP exchange to be completed successfully. Under certain conditions, this assumption cannot be guaranteed, especially when mobility is taken into consideration, as usually happens in the Ecumene network, devoted to cultural heritage information management. In such cases, a proper mechanism to retrieve the correspondent peer IPv6 address must be taken into account.

The IP Multimedia Subsystem (IMS) defined by the 3rd Generation Partnership Projects (3GPP and 3GPP2) represents today the global Service Delivery Platform (SDP) standard for providing multimedia applications in Next Generation Networks (NGN). It defines an overlay service architecture that merges the paradigms and technologies of the Internet with the cellular and fixed telecommunication worlds. The architecture enables the efficient provision of an open set of potentially highly integrated multimedia services, combining web browsing, email, instant messaging, presence, VoIP, video conferencing, application sharing, telephony, unified messaging, multimedia content delivery, etc. on top of possibly different network technologies. Also interworking with the Internet and legacy networks is supported. As such the IMS enables various business models for providing seamless business and consumer multimedia applications.

The IMS Playground is a gathering of all major IMS core components, originating from own developments as well as major industry players, which can be used by academic and industrial partners for early prototyping of new IMS related components, protocols, and applications.

FOKUS will come up with a presentation of the testbed, shows multimedia applications and explains the usage and business models for the Playground.

We show how a researcher can use the ETOMIC infrastructure in order to define and run experiments in the paneuropean measurement network that the EVERGROW project is deploying. We describe the basic behavior of the system, the user interface and then create an example experiment, run it and download the results.

Mobile ad hoc networking allows the development of several infrastructure free applications. One of the arguments we focused on is the possibility of deploying a set of services in areas lacking of low-cost and wide band connectivity to Internet, as rural or mountain communities. The main idea is that it is possible to transfer data by mobile vehicles such as bus, letter carriers and other similar means, by equipping them with an ad hoc kit able to discover clients capable to receive news, e-mail or, generally, to act as a server for other kind of services. In this context we used AODV protocol to interconnect the hosts involved in the test-bed and SLP to develop some applications to offer e-mail and news pushing services over discontinuous connectivity.

The UnWiReD Lab's wideband radio testbed is a remotely controlled and openly accessible platform for wireless research. The testbed's design is motivated by the following requirements:

Our team has designed, programmed and installed a flexible autonomic and adaptive packet network test-bed. Our project can be viewed at http://san.ee.ic.ac.uk. The current test-bed is based on some 60 wired routers, which use PC's running Linux, to provide a flexible programmable network protocol and control environment. Additionally we are currently installing a connected ad hoc wireless extension based on PDA's. The packets carried by the test-bed are fully IP compatible, and are handled as IP packets by IP routers. Furthermore all routers themselves can be run as IP routers. This allows our test-bed to receive traffic from, and forward traffic to, the Internet. It also allows the test-bed to be broken up into sub-components which can be interconnected via the Internet.

The current capabilities of the test-bed include:

The roll-out of the 3GPP (3rd Generation Partnership Project) IP Multimedia Subsystem (IMS), that can be forecast to happen in the next few years, will introduce mobile users to a new class of telephone-class multimedia services based on the Internet Protocol. Investigation is already in progress about an evolution for the 3G networks based on heterogeneous high-speed access networks allowing new multimedia services and a seamless global coverage (Beyond 3G - B3G).
The proposed demo is based on the testbed developed by the Co.Ri.TeL. Consortium in the framework of the PRESTO Project, whose objective is to provide a suitable and common platform, inspired to the IMS ideas, for experimenting a wide variety of B3G SIP-based mobile services. Various services have been experimented on top of the testbed, including a multi-user video conferencing architecture, added-value user-defined multimedia services, a multimedia message box and a video-on-demand provisioning infrastructure.
In particular, this demo will show, within an IMS framework, an audio-video message box service integrated with a CPL (Call Processing Language) service infrastructure which allows users to define personalized added-value services related to session management. The video content of the stored messages is then compressed by means of an innovative video compression technique based on the theory of the Focus-of-Attention (FoA). Such compression is performed in order to obtain a bandwidth saving in the delivery phase.
The service provisioning mechanisms are built within a common security framework, providing an approach which is independent from the various possible underlying radio access technologies. In particular, the security capabilities of the developed architecture comprise user and network authentication and key exchange, authorization to service access and IP-layer protection of the SIP signalling through cryptography and data authentication.

The WILMA project (wireless Internet and location management architecture) is sponsored by Provincia Autonoma di Trento and participated by ITC/irst (Istituto per la Ricerca Scientifica e Tecnologica), the Department of Computer Science and Telecommunications of the University of Trento and Alpikom S.p.A. The project aims at studying solutions for integrating different protocols and wireless access means to support context-dependent computing. Research problems addressed include finding the optimal wireless access means for specific contexts, migrating information between different environments, deriving and using the user location, anticipating user requests based on previous history, and optimally adapting to the user needs without direct user intervention. An important part of the project is dedicated to evaluating results in an "Open Laboratory" consisting of several wireless area networks connected through a fixed broadband infrastructure, which is explained and demonstrated during the conference.
