LAN switch

Concentrator-based traditional LAN

Obviously, the main reason for the rapid implementation of switches is the lower cost of the devices themselves compared to traditional routers and a significant reduction in the costs of organizing and maintaining networks. Being a MAC-level device, the switch does not require any configuration and provides a plug-and-play solution (this applies primarily to simple switches). Switches can easily solve the problem of bandwidth expansion and can work in networks with traditional routers, ensuring the division of the network into segments, then connected by routers. Because the network looks flat at the link layer, all additional routing services must be performed by traditional routers. Thus, the switches in the workgroups allow you to effectively segment the network, leaving the routers with communication functions between the segments.

Another reason for the rapid growth in the popularity of switches is that they are optimized for solving various network problems (in particular, for organizing work groups). Since the needs of working groups are primarily associated with a high exchange rate and providing non-blocking ways of transferring traffic between group members, LAN switches contain a switching engine as a core. Mass production of ASICs has led to a significant drop in prices. Additional high-speed ports (uplink) for connecting to servers, routers or highways provide users of workgroups with the satisfaction of all arising needs. Flexible and scalable bandwidth allocation makes LAN switches an important part of the process of upgrading existing networks based on shared environments. The ability to easily transfer from one network point to another provides high investment efficiency, since when changing tasks or network structure you do not have to buy new devices to replace existing ones.
