Video lecture on Ethernet switches. Lectures for the "Computer Networks" course - https://goo.gl/0aIOuf Course page - http://www.asozykin.ru/courses/networ... Switched Ethernet is a completely different networking technology than classic Ethernet. The main difference is the elimination of a shared data transmission medium. Therefore, collisions do not occur. Switched Ethernet requires a new device: a switch. A switch uses a mesh topology. A switch operates at the data link layer: it analyzes the data link layer header and forwards data only to the recipient computer, rather than to all computers on the network, as a hub does. Key features of switches: 1. Switching table - Mapping MAC addresses to switch ports. 2. Reverse learning algorithm - Populating the switching table. 3. Transparent Bridge Algorithm - Switch Frame Forwarding. Advantages of switches: High performance and scalability High security.
