The current broadband status in the region is being described, while the results of a survey on broadband usage and demand are being presented.
The paper proposes some Recommendations that should be adopted in the region of Western Greece in order for the appropriate broadband infrastructures to be developed and adopted so as to contribute to economic growth and to tackle any possible cases of “digital gap” between the citizens of our country.1 aBouras, Christos1 aKapoulas, Vaggelis1 aTsiatsos, Thrasivoulos1 aAlexiou, Antonios1 aIgglesis, Vaggelis1 aParaskevas, Mixalis1 aPapagiannopoulos, J  uhttp://telematics.upatras.gr/telematics/publications/broadband-status-region-western-greece-overview-and-recommendations?language=en01198nas a2200193   4500008004100000245007500041210006900116260001400185300001500199520050900214100002100723700002300744700002200767700002300789700002400812700001700836700002400853856012700877       2005                        eng d00aDeployment of Broadband Infrastructure in the Region of Western Greece0 aDeployment of Broadband Infrastructure in the Region of Western   c7 October  a 588 - 5933 aThis paper presents the work that is taking place in the Region of Western Greece in order to develop state-of-the-art broadband infrastructure.

The services were designed taking advantage of features provided by the MPLS technology and also by using the DiffServ architecture. The supported QoS services include the IP Premium that tries to provide zero packet loss as well as minimum delay and jitter and the Less Than Best Effort service. In addition we implemented a management tool for the service. The scope of this tool is to allow the users to manage their QoS requests (make a new one, edit, delete or view a request). Also the tool performs admission control and produces the necessary configuration that must be applied on the network in order to implement every service’s request.</p>

The wireless infrastructure, the connection of the
wireless island to the rest network and the interconnection between the neighboring schools a near one participating in
the wireless network. The wireless connection supports Point-to-Multipoint technology [3] and uses the frequency band
2,4 Ghz to 2,4835 Ghz. The reserved bandwidth of this wireless LAN is order of magnitude 11 Mbps. In each school the
bridge device is connected to a newly equipped Fast Ethernet switch interconnecting the internal schools network to the
wireless network. Between the schools a fast Ethernet network is built using copper and Fiber optic cabling. The
interconnection of the wireless network upstream to the backbone is achieved with the use of the link between the E.A.O
and the local main distribution node of the EDUNET network. This link had to be upgrade because it will carry the
traffic from the wireless network too. The selected solution was the VDSL technology by engaging the appropriate
modems over a two-wire leased line between the E.A.O and the main node. We have a selected point in each school unit
that wireless bridge and antenna will be installed. The wireless bridge must stand near to antenna because long cabling
distances will produce noise in the transmission signal. The wireless bridge will be housed at waterproof cabinet, which
offers all the necessary specifications for protection and electric feeding. The waterproof cabinet is installed at the
antenna pylon.1 aBouras, Christos1 aKaraliotas, A1 aParaskevas, Mixalis1 aPapoutsis, V1 aNtokos, Christos1 aDrosopoulos, N  uhttp://telematics.upatras.gr/telematics/publications/wireless-school-network?language=en01131nas a2200157   4500008004100000245008000041210006900121260001700190300001300207520053700220100002100757700002000778700002400798700002200822856012900844       2002                        eng d00aPolicies for Content Filtering in Educational Networks : the Case of Greece0 aPolicies for Content Filtering in Educational Networks the Case   c24 - 29 June  a 57 - 623 aAn increasing number of nations connect their schools on the Internet as an

"Winds of Aiolos”. This project is subsumed in the framework of the European Community
Action "Operational Program for the Education and Initial Vocational Training - Odysseia".
Computer Technology Institute (CTI) has the responsibility for the design and the
implementation of the project. On the basis of the influence of the networking technologies to
the educational activities and according to the international experience, the usage of the
network to the educational procedure acts as knowledgeable object, information source,
learning tool and communication tool. The main object of the project is the implementation of
a network infrastructure for the interconnection of school laboratories and educational
administration offices and the provision of network services in a wide range. It forms a closed
educational network, which is based on the Greek educational and research backbone network
(GRNET). The Greek school network statistics show that the students prefer the Greek
Domain. The educational units of the Greek School Network still act more as consumers than
as creators in the information society.1 aBouras, Christos1 aParaskevas, Mixalis1 aGanos, Petros1 aAdamopoulos, N1 aKaraiskakis, D  uhttp://telematics.upatras.gr/telematics/publications/winds-aiolos-how-connect-greek-schools-internet?language=en
