network monitoring analysis tool. The network resources
were configured to support SNMP under various operating
systems, thresholds definitions and events. The data were
collected by a network monitoring system and handled
according to the values of the variables or the event type. A
real- time report to a database was established via adaptive
scripts. A Network Node Manager (NNM) will inform an
external, remote database about the network status by
sending real time data containing alerts and events. The
whole tool is called Network Management Analysis Tool
(NMAT).1 aBouras, Christos1 aGanos, Petros1 aAravantinos, E1 aIlias, A  uhttp://telematics.upatras.gr/telematics/publications/approach-methodology-and-implementation-network-monitoring-analysis-tool?language=el01297nas a2200133   4500008004100000245007000041210006600111300001300177520079400190100002100984700001801005700001801023856012201041       2003                        eng d00aThe deployment of IPv6 in an IPv4 world and Transition Mechanisms0 adeployment of IPv6 in an IPv4 world and Transition Mechanisms  a 86 - 933 aIt is stated that the new version of the IP protocol, IPv6, is
the answer to the majority of the problems that were raised
during the enormous expansion of the Internet and its
transformation to a global communication platform with
commercial scope. At the same time it is also stated that
IPv6 dominance will not be easy and there will be a period
when the two versions of the protocol will co-exist. In this
paper we describe some of the main transition mechanisms
that can be deployed in order to facilitate the transition
process to the new version of the IP protocol. Furthermore,
the presented mechanisms are discussed regarding their
usability, usefulness and manageability. Describes the way
some of these mechanisms were applied to the Greek
Research & Technology Network (GRNET).1 aBouras, Christos1 aKaraliotas, A1 aGanos, Petros  uhttp://telematics.upatras.gr/telematics/publications/deployment-ipv6-ipv4-world-and-transition-mechanisms?language=el01472nas a2200157   4500008004100000245008300041210006900124260001800193300001300211520087600224100002101100700001801121700001901139700001601158856014001174       2002                        eng d00aHTTP Traffic Simulation and Evaluation for multiple Users in Intranet Network 0 aHTTP Traffic Simulation and Evaluation for multiple Users in Int  c14 - 17 April  a 63 - 673 aIn this paper we describe the architecture and design of a network-stressing tool developed to simulate and evaluate the HTTP requests and responses of hundreds of users. There are two major issues that have to be considered when designing and implementing such a simulation tool, the reliability evaluation and the user “friendly” environment. In our application we use a mechanism exploiting Intranet technology to stress the tested network and confirm the performance, proper operation and delay issues. We have also implemented an easy interaction with the user considering the creation of the scenarios and the presentation of the simulation results, pointing out the problems and the network’s status. Finally, we examined through a number of experiments using different simulation scenarios the behavior of the Intranet by load balancing the simulated users.1 aBouras, Christos1 aGanos, Petros1 aAravantinos, E1 aKokkinos, P  uhttp://telematics.upatras.gr/telematics/publications/http-traffic-simulation-and-evaluation-multiple-users-intranet-network?language=el00965nas a2200145   4500008004100000245006300041210006200104260001700166300001300183520045400196100002100650700001800671700001800689856011200707       2002                        eng d00aTransition Strategies from IPv4 to IPv6: The case of GRNET0 aTransition Strategies from IPv4 to IPv6 The case of GRNET  c16 - 18 July  a 89 - 963 aIn this paper we describe the results that came out from the project of employing the IPv6 protocol over the Greek Research & Technology Network (GRNET). In the way of this process one of the big issues that had to be considered was the transition strategy that would be deployed. The main goals of a transition strategy are to be smooth enough and therefore to put the less of configuration overhead to the end users and the network administrators.1 aBouras, Christos1 aKaraliotas, A1 aGanos, Petros  uhttp://telematics.upatras.gr/telematics/publications/transition-strategies-ipv4-ipv6-case-grnet?language=el01805nas a2200169   4500008004100000245006300041210006200104260002000166300001300186520121800199100002101417700002401438700001801462700001901480700001901499856011701518       2000                        eng d00aWinds of Aiolos: How connect the Greek Schools in Internet0 aWinds of Aiolos How connect the Greek Schools in Internet  c19 - 20 October  a 27 - 373 aIn this paper, we present the first Greek School Network, which is implemented by the project
"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=el
