In this project - which is co-funded by the European Union - our team is responsible for the development of the Advanced Network Services over the Campus Network, which is being established during the project. In the following chapters we first present the general perspective and the architecture of the integrated system which offers the set of advanced services to the University community. We then describe in detail the different services (WWW and Intranet, On-line teletraining, Computer supported cooperative work, and Off-line teletraining). A key characteristic of the system is the integration of existing commercial tools, with tools that we are developing for the specific needs of the foreseen users. It is evident that this system can be considered as a pilot project for large and demanding user communities, as is the case with the University of Patras.}, author = {Christos Bouras and Paul Spirakis and Vasilis Triantafillou and J Garofalakis and J Tsaknakis and J Tzimas and A Tsakalidis and I Antoniou and D Karageorgopoylos and B Basiliadis and P Kappos} } @conference {2840, title = {Hermes Service: Distributed Hypermedia Educational Services on Demand}, booktitle = {ED-MEDIA/ED-TELECOM 97, Calgary, Canada}, year = {1997}, month = {14 - 19 Jne}, pages = { 19 - 24}, abstract = {In this paper we present a distributed HypERMEdia SERVICE (HERMES SERVICE) which supports integrated capabilities for distance education and learning purposes. Hermes service consists of hermes servers and hermes browsers. The users are connected with the service using hermes browsers and retrieve hypermedia lessons organised in thematical units. The lessons are stored in various distributed Hermes servers which retrieve the requested lesson and transmit it to the corresponding browser on on-demand basis. The requested lesson is presented to the user according to a well defined presentation scenario. The media objects are rendered in a synchronized manner according to the spatio-temporal relationships existing among them. Finally, special monitoring mechanism controls the state of the network and adjusts the presentation process so as to improve presentation quality.}, author = {Christos Bouras and Vaggelis Kapoulas and Paul Spirakis and D Moiras and V Ouzounis and I Antoniou and D Karageorgopoylos} }
