MAIN PROJECTS

Design, management and maintenance of the Advanced Telematics Network of NTUA. The network was designed to provide high quality voice and data services to the university community and to provide a high-tech infrastructure for educational and research activities. The Network Management Center (NMC) provides management and troubleshooting (Help Desk) 12 hours per day.

Technical coordination of GRnet - the Greek National Research Network and its international connections. GRnet (www.grnet.gr ) offers high speed INTERNET connectivity among all major Academic and Research Institutions of Greece. Its technical management is coordinated by the Network Management Center of NTUA.

Metropolitan High Performance Network For Teleteaching. Initially this network interconnects the National Technical University of Athens, the University of Athens and the Athens University of Economics and Business.
The main aims of the project include:

  • The interconnection of the three Universities at the speed of 155/34Mbps
  • Deployment, design and operation of three 'virtual classrooms', one per University,
  • Digital video facilities using a 'Video on demand' server,
  • Multimedia communications for tele-teaching applications.
  • Transfer of medical images of high quality from the University Hospitals (Areteion, Egenition, Eugenidion) to the research labs for the University of Athens, the Technical University of Athens and the Athens University of Economics and Business.

Greek Universities Network (GUnet). NMC cooperates closely with GUnet (www.gunet.gr) the consortium of Greek Universities for Advanced Networking Services by providing the technical management for interconnecting all Greek Universities and Technological Institutions to GRnet.

 

QUALITY ASSURANCE PROCEDURES

The quality of network services within a Higher Education establishment depends very much on the procedures applied. The Network Management Center has introduced a kind of informal 'service level agreement' with all members of the NTUA's Academic community.

NMC is accepting user requests and complains via standardized hard copy forms (they are also available in electronic way via WWW). These forms can be send to NMC via snail or electronic mail or via fax. As soon as the filled form arrives in NMC the responsible technician fills a trouble ticket. Copies of these trouble tickets including a description of the action taken place are being send to the user. An integrated information system has been developed in house to support the trouble ticket mechanism.

APPLICATIONS FOR NEW CONNECTIONS
New connections to the voice and data networks are established within two working days provided there is no extra need for equipment.

ACCOUNTING
Personal statements are posted internally within the first week of the month.

DEALING WITH USERS REQUESTS AND COMPLAINS
An official answer is given via letter to any of users requests and complains within three working days.
In case that the above deadlines can not be meet by NMC the user receives a letter within one working day.
