Abstract [en]

I have performed my thesis project at ATEA in Lulea, for Coop Norrbotten. The purpose of this project was to design, implement and document a new and enhanced network solution for use in Coop Norrbotten's grocery stores, and to construct a detailed rollout guide to handle the implementation procedure. Senior consultant Leif Häggström from ATEA supervised the project.I was given two primary issues to address in the new network design; the new solution should be more secure and more scalable than the old design. With my new design I also tried to address some other issues such as efficiency, performance and resiliency. The network equipment that was initially available for the new design was: • 1x Cisco 1811 Integrated Services Router• 1x 3Com 3226 L3 access switch• 1x HP Procurve 1800 PoE switch• 2x Wireless Access Points from Trapeze (Juniper)During the course of the project, it was decided that the 3Com 3226 platform should be replaced, due to its age and limited functionality. The old switch was replaced by a Cisco 2960-S switch.During the first week of the project I gathered information about the functionality of the network equipment, and drew up a theoretical design for the new network. The second week was used for documenting the existing topology and the physical conditions for the implementation procedure. During the second week, I also started designing a Zone-Based Policy Firewall solution for the network. The third week was allocated to setting up and testing the new network model in a lab environment. At this point I also started working on the implementation guide. The beginning of the fourth week was used for further testing, this was also when the decision to replace the 3Com switch was made. The second half of the fourth week was used to preconfigure the new Cisco switch and the shop's router. The implementation took place during the fifth and last week of the project. The results of the project were: the physical implementation of the new network model, and the rollout guide to handle the implementation procedure.One of the conclusions i reached after the project was finished, was that it is difficult to construct a simple and modern network solution without access to modern equipment. It is possible to construct a quasi-modern solution based on older equipment, but the solution becomes increasingly complex as the designer must find many workarounds for solving the problems caused by the older network equipment.
