Directory Description

What is the Greek Schools Network;

The Greek Schools' Network (GSN - www.sch.gr) is the educational intranet of the Ministry of Education and Religious Affairs (www.ypepth.gr), which interlinks all schools and provides basic and advanced telematics' services. Thus, it contributes to the creation of a new generation of educational communities, which takes advantage of the new Informatics' and Communication Technologies in the educational procedure.

The implementation of the Greek Schools' Network is funded by the Framework Programme for the Information Society (www.infosoc.gr), in close cooperation between the Ministry of Education as well as 12 Research Centers and Highest Education Institutes, specialized in network and Internet technologies.

Educational Exploitation of the Greek Schools Network

The current design and implementation of the Greek Schools Network focuses in providing useful services to all members of the basic and middle education community, fulfilling among others the following goals:

  • Access to telecommunication and informatics services
  • Access to digitized educational material
  • Distance learning, e-learning
  • Encourage collaboration
  • Information and opinion exchange
  • Conduct of thematic discussions, seminars, lectures, etc.
  • Access to digital library services
  • Communication and Cooperation of all educational degrees
  • Communication with European educa-tional networks
  • Facilitate complimentary educational programs
  • Provide education to individuals with special needs or disabilities
  • Inform, educate, entertain

Network architecture

The network is hierarchically structured into three layers:


Core Network: The Greek Schools Network interconnects with the Greek Research and Technology Network (GRNET, www.grnet.gr), in seven main points (Athens, Thessaloniki, Patras, Heraclion, Larisa, Ioannina and Xanthi), using it as its core network.
Distribution Network: The Greek Schools Network installs in the capital of every prefecture network and computational equipment, thus ensuring optimal access of the prefecture's school to the network and its services.
Access network: It is used to directly and efficiently interconnect the schools to the prefecture's access point. The telecommuni-cation junctions used to interconnect each school are selected on the basis of financial and technical criteria from an array of available options:
  • Digital ISDN circuit (bandwidth: 64 - 128 kbps)
  • Analog leased line (0,128 - 2 Mbps)
  • Public Switched Telephone Network circuit (56 kbps)
  • Wireless link (10 Mbps)
  • VDSL circuit (10 - 15 Mbps)
  • ADSL circuit (384/128 Kbps, pilot implementation)

Users' categories

In order to maintain the educational orientation of the network, its users are certified individuals, educational or administrative entities of the National Education. In particular, the users are divided in the following categories:

  • Schools :
    At least one user account have been provided to all middle grade education schools and 92% of first degree education schools.
  • Administrative units :
    At least one user account has been provided to more than 2.282 administrative units of National Education.
  • Educational staff :
    The Greek Schools Network offers fully personalized access to all educational staff, with the dial-up service being broadly used under certain terms.
  • Students :
    Network access is provided to students through the school laboratories. In addition, personalized access is offered to second grade students since September 2008.
  • Administrative staff :
    as with educational staff

Networking progress

Currently, all educational and administrative units of the second educational degree are part of the Greek Schools Network, as well as (approximately) 96% of the first degree educational units


The Greek Schools Network Services have been broadly accepted by the educational community. A typical degree of usage is the number of e-mail accounts, which is constantly rising, as is evident by the next diagram. Another indication of this broad acceptance is the number of the web portal visitors (approximately 5.6 million during the last 35 months).

In order to facilitate the needs of the educational staff trained in Telecommunication and Informatics Technologies (http://www.de.sch.gr/epimorfosi), the Greek Schools Network offers personalized dialup accounts to the trainees, as well as the executive educational staff and Informatics professors. The number of personalized accounts is expected to reach a ceiling of 40,000 by the end of 2004.

The Greek Schools Network is also exploited to interconnect other important units, such as Public Libraries, Second Opportunity Schools, the General State Archives, etc.

Greek Schools Network and Broadband

In order to achieve the objectives of e-Europe 2005 regarding provision of broadband access to all schools, the Greek Schools Network is upgrading its distribution network by installing broadband connections (installation of 500 ADSL connections, bandwidth 384/128 kbps, during the 1st phase, in addition to more than 250 wireless links, bandwidth 10 Mbps).

As far as wireless communications are concerned, 13 distinct wireless networks are in operation in the following cities: Athens (3 networks), Thessaloniki (2 networks), Kalamata, Siros, Volos, Xanthi, Kilkis, Ioannina, Rethimno and Chania.


The available bandwidth of the networks mentioned above allows for the provision of advanced and high quality telecommunication and informatics services to the units concerned, as well as significant lowering of the telecommunication costs

Greek Schools Network Implementation Scheme

The contribution of Research Centers, Universities and Technological Education Institutes under the supervision of the Ministry of Education has been critical in the implementation and operation of the Greek Schools Network.

This cooperation has guaranteed both the equal overage of all geographical apartments of Greece, as well as the immediate users' support by proximate institutions. In addition, it promotes the creation and consolidation of solid relationships amongst all educational degrees, while assuring the transfer of technical knowledge to the Ministry of Education permanent structures, contributing to the viability and the permanency of the attempted interventions.

In particular, the cooperating institutions see to:

  • Monitor the implementation as well as the qualitative and quantitative acceptance of network structure development projects in educational and administrative units of the first and second educational degree.
  • Provide and administrate telecommuni-cations and informatics services
  • Administrate the core and distribution network
  • Offer technical support to the network's users
  • Hold competitions of bids for acquiring network equipment
