Different lan Technologies

Different local area profits Technologies1. AIMTo show or so un exchangeable lan technologies and to design a network based on these lan technologies and to simulate these networks by a simulation tool know as opnet and by putting diametrical make fulls on these networks and to study the feat of these networks.2. OverviewLocal area networks (LAN) are a group of devices which communicate with severally other in a small geo interpretical area equivalent within a room or within a building. on that point are diametric topologies in LAN which are designed agree to usage, cost, amount of work flow. The different topologies are star topographic anatomy, bus topology (Ethernet), ring topology, FDDI.The main aim of this project is to design network and equality different lan topologies and to simulate these networks by putting different network loads and to analyse how these networks behave to the different traffic loads and by running the simulation for a long time. Analyse the results and then to influence which topology is the best.This project has been suggested by Dr Diane Gan.This project meets the guidelines of the Masters project and the requirements of the course of study that i am studying and as i will be able to design an network and simulate it using opnet and to vary the traffic load and to analyse the result of the simulation and to decide which network topology is the best and efficient.After completion of the project i would be in a situation to tell about different parameters of the network give care delays, packet inter arrival time, link utilisation, packet loss.3. ObjectivesLiterature review of different LAN topologiesTo design different LAN topologiesSimulate different LAN topologies by varying the traffic loads say about 20%, 40%,70%,80%Analyse the quality of service (QOS) when an particular load is applied.To compare and analyse the results based on these simulationsTo decide which topology would be the best, looking at the result s of the simulations and to suggest which topology would be better.How the objectives will be achievedResearch on different networking books and different publications like IEEE, ACM etc.To learn to use opnet.Using opnet to design different LAN networks.To simulate these networks with different traffic loads like database traffic, ftp traffic, email traffic, web surfing, voip, delineation streaming, printing.To collect and put the result of these simulations on spreadsheet and to analyze the results.To check the results like loads at servers, packets loss, packets delivery time, utilization of the links.To plot the results on graphTo decide which network topology is the best based on the results.4. ResourcesTo nail this project i would requireOpnet ModelerA computer with mellow configuration so that i could store the network models and the simulations.6.
