Network segmentation
Network segmentation in computer networking is the act or profession of splitting a computer network into subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting performance and improving security.
Advantages
- Reduced congestion: Improved performance is achieved, because on a segmented network there are fewer hosts per subnetwork, thus minimizing local traffic
- Improved security: Broadcasts will be contained to local network. Internal network structure will not be visible from outside
- Containing network problems: Limiting the effect of local failures on other parts of network
- Controlling visitor access: Visitor access to the network can be controlled by implementing VLANs to segregate the network.
