Increasing competitiveness has become a major factor in the economic climate of today. The attempt to strengthen the infrastructure of the informatics system of the government has not been very successful in Hungary. That is why the development and creation of a nationwide, streamlined and strategically built approach is necessary that would gather the relevant and important national and local governments into one network. This would, in the long run, be time and cost efficient.
In the first part of my work, I will present the basic concepts and functions of the IP/MPLS networks. I will also overview the VPN services that use the network, as well as their classification, network architecture, functions, relationship to the MPLS technology and also the specific topology in which we will use it. Similarly I will present the used guidelines and the process that deal with network failures.
In the second part of my thesis I will plan a similar network that will connect and provide the communication channels for different national entities (between 19 and 51), with different protection requirements. Firstly, I had to gather the requirements of these networks. To evaluate the utilization of the network I have created certain service packages that will allow me to gather quantifiable data with regards to traffic.
I will provide a thorough look of the network technologies and also of the available choices. Then I will present the equipment model, as well as the junction- and link models.
Using the FLEXPLANET software, developed by the Department of Networked Systems and Services, we will plan and evaluate different versions of the IP/MPLS/WDM networks according to their requirements.
Finally, we will analyze the traffic carried by these networks and simulate a link failure. Furthermore, by estimating a yearly growth rate we will approximate the traffic in the 10th year and also simulate a link failure.
