This report provides a comprehensive analysis of Local Area Networking (LAN) technologies. It begins with an introduction to LANs and explores various topologies like bus, star, ring, and mesh, establishing the suitability of star topology. The report then analyzes traffic-intensive services, network performance, and Quality of Service (QoS). It evaluates LAN concerns and recommends a hierarchical network model to enhance security, reliability, and performance. The second part of the report focuses on designing network infrastructure, evaluating network components, and addressing security, QoS, and redundancy. It also covers user scalability and availability. The third part delves into technology and security configurations, including VLANs, DHCP, ACLs, bandwidth aggregation, and trunking, along with LAN infrastructure and security measurements. The report concludes with a discussion on improving LAN reliability, security, and performance, including network-to-server traffic optimization. The report uses various sources to support its claims.
