Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with CSMA/CD (Carrier
Sense multiple access with Collision Detection) protocol, and greatly reduced
unnecessary transmissions.
This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the
store-and-forward technology's approach of inspecting each packet to
intercept corrupt or redundant data, switching eliminated unnecessary
transmission that slow the network. By employing address learning, which
replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex of each port, based on the
