Implementation and Management Approach
The project was coordinated centrally by the lead partner, with direct reference to work package leaders, by e-mail, telephone calls, videoconferencing and announcements on the project and portal web sites. Particularly, activities were coordinated and files exchanged through a dedicated project web site and the main dissemination tool of the project, the ITHANET Portal, at later stages of the project served the coordination of actions and the internal discussion of consortium topics in its Forums section.
The project incorporated multiple workshops on eInfrastructure and specifically grid-related tools. To promote take up of eLearning approaches, three dedicated hybrid courses on community-specific topics were organized and provided by live streaming and streaming on request
Technology solution
The ITHANET Portal resides on http://www.ithanet.eu, where information is accessible using a standard web browser through a single web site. The site structure is user friendly with a single top menu bar and drop down menu as the main means of navigation, besides additional search and navigation options. The top-level contents organisation includes direct access to the Home, News, Events, Forums, Organisations, Featured Items, Databases and Newsletter subpages. Updates of the portal contents are announced using e-mail alerts for registered users, and a newsletter is circulated every four months.
For virtual real-time communication, two systems were implemented sequentially: the first for secure communication using a package of open-source eInfrastructure tools (ITHANET eInfrastructure Tools), and the second for simpler and more user-friendly communication via Adobe Connect.
In case of ITHANET eInfrastructure Tools, the end-user tools comprises the AccessGrid tools VIC and RAT for video and audio communication, respectively, and a web browser for real-time text-based chat. Secure network layer access is provided by OpenVPN, where the client uses a Grid-compliant X.509 certificate as proof of identity. The central service is a modular programmable UDP packet reflector that provides multi-point data distribution among the participants and central monitoring and logging features. Another central service is a chat server.
The client side of the Adobe Connect system is a Flash-based application that provides audio and video communication, and a host of other features, such as text chat, persistent file sharing, whiteboard sharing, application sharing including remote control of applications, discussing notes, and opinion polls. It can be used as a standalone application with Shibboleth-based authentication, or it can be accessed using OpenVPN with authentication based on Grid-compliant X.509 certificates. The central service is the Adobe Connect server, which has been licensed by the WP2 lead partner.
