An E-learning system comprising of voice and data distribution service has been designed in this project using a secondary school (Alhudahuda College) model as a case study. It involved identification, determination and specification of data communication products and services that best satisfy user need in a way that gives room for network scalability, redundancy and effective manageability. The project also focuses on the design of an enterprise network by effectively deploying technologies and protocols as Voice over (Internet Protocol) IP, Access Control Lists, Enhanced Interior Gateway Routing Protocol, EIGRP routing, Fibre Optics, Variable Length Subnet Masking, VLSM for addressing, Inter Virtual Local Area Network, VLAN routing, Network Address Translation, use of Dynamic Host Configuration Protocol, DHCP and wireless routing. This project should be useful to Network Communications Engineers as it covers the major requirement that necessitates an enterprise network.
