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). JF - EUROMEDIA 2003 – COMTEC, Plymouth, UK ER - TY - JOUR T1 - The deployment of IPv6 in an IPv4 world and Transition Mechanisms JF - Internet Research: Electronic Networking, Applications and Policy, Emerald, Volume 13, Number 2 Y1 - 2003 A1 - Christos Bouras A1 - A Karaliotas A1 - Petros Ganos AB - It 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).

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.

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.

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.
