Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with Carrier Sense Multiple Access with Collision Detection protocol, and greatly reduced unnecessary transmissions.
Switches have revolutionized the network world in three major ways. First, by using a switch you can have two-way, simultaneous transmissions over the same port (full duplex), essentially doubling the bandwidth. Second, by reducing the collision domain to a single switched-port “Carrier Sensing” is eliminated. Third, using store- and-forward switching, unnecessary transmissions can be eliminated to avoid congestion.
Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. You may need to disable auto-negotiation and flow control for some networking operations involving legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port.
