History

The first efforts to create a national network of schools started by the Ministry of Education in 1996, with actions implemented by the Computer Technology Institute as the “Pilot Schools Network of Achaia” (1996), “Odisseas” (1997), “Winds of Aeolus” (1998) of the action “Odisseia” of CTI.

The Greek School Network was formed as a single national network of schools in 2000. From the beginning of the creation of GSN, CTI undertook the strategic and technical coordination of all involved entities i.e. Universities.

The connection of schools of Secondary Education was completed in January 2011. Subsequently, priority was given to the connection of primary schools and to the assignment of personal accounts to teachers. The network grew rapidly during the period 2000-2006 with co-funded resources. In 2008 the Data Center of GSN was designed by CTI and acquired with resources from OPIS (Operational Program ‘IS’ )which gave a major push to the online services of GSN. During 2006-2009 the upgrade of the connections of more schools to broadband took place. Today broadband index reaches 98.9%. Since 2010 the upgrade of school connections with fibers began and more than 380 schools have now super high speeds which constitute an internationally high index.

The GSN as a public network is working closely and harmoniously with the other two national networks GRNET (www.grnet.gr) and SYZEFXIS (www.syzefxis.gov.gr) and plans the next day (in terms of access) which will be the transition of school’s circuits to the, under construction, Public Sector Network.

Since 2011, and in accordance with article 32 of N3966/2011, the administration and management of GSN is performed by CTI. For this purpose, CTI established the Greek School Network and Networking Technologies Directorate (http://nts.cti.gr), which cooperates with Universities and Technical colleges with specialized networking groups. These entities both support the school/administrative units of their region and some of them develop and support specific web and online services.

 

Infrastructures

Network Equipment

GSN is the largest public network in Greece in the number of users it serves. In particular, it interconnects and also connects on the Internet more than 15.700 schools, a community of 1.300.000 students and 160.000 teachers. GSN applies modern web technologies and is one of the first five school networks in the world that adopted IPv6 protocol.

GSN owns 118 nodes in all country capitals and in the largest Greek cities. The number of nodes is expected to reach 120 by the integration of the interconnection of GSN with the Metropolitan Optical Fiber Networks of Municipalities. The technical team of CTI that is responsible for the proper functioning of the backbone network manages more than 200 network devices daily. The average network traffic of GSN to the Internet is more than 9 Gbps daily.

Recently, GSN upgraded its network infrastructures of the school complex of Grava (the largest in Greece), using the most modern optical and wireless technologies to serve more than 3.500 users.

Main data center Equipment

The computing infrastructure of GSN is equally stronger. Through this infrastructure, GSN provides its services to more than 215.000 members (schools, administrative units, teachers, students, etc.)

The main data center of GSN is located in Athens. Three other (of smaller capacity) data centers are located in Thessaloniki (one) and in Patras (two).

The technical team of CTI that is responsible for the uninterruptible operation of data centers manages daily more than 100 servers and network devices.

 

Main Services

Broadband Connection

In all public schools and administrative units, a free broadband connection is provided. The connection charges of public education units with GSN and Internet burdens the State Budget. The units abroad do not receive this service. The connection technologies used are ADSL (mainly), optical fibers and selected lines (rarely). Broadband in GSN is 98.9% and analytically:

The main objective of GSN for the next five years is the further upgrade of the medium speed connections, ie. up to 20Mbps for speeds of at least 50Mbps (VDSL technology) and further school connections with optical fibers in order to meet the expanding needs of schools.
