Network design topology refers to the arrangement of the various elements of a computer network, including its devices and transmission media.
Star Topology centralizes a switch or router to improve performance and simplify troubleshooting.
Security
Segmentation: Dividing the network into smaller subnetworks (subnets) using routers or firewalls to control access points and limit the spread of security threats.
Access Control: Implementing access controls on network devices to restrict unauthorized access, using firewalls and access control lists (ACLs) in routers.
Performance
Scalability: Designing the network so that it can expand to accommodate growth without necessitating complete redesign or performance degradation. This can be done by using fibre optic rather than UTP or having switches with more ports than initially required.
Redundancy: Including redundant paths and devices (like additional switches and routers) to ensure network availability during component failures. Having UPSs with switches and routers provides redundancy.
Bandwidth Management: Using Quality of Service (QoS) protocols to prioritize critical network traffic and manage bandwidth usage effectively.
