Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a network,
eliminating congestion problems inherent with CSMA/CD (Carrier Sense multiple
access with Collision Detection) protocol and greatly reducing unnecessary
transmissions.
This revolutionized networking. By allowing two-way, simultaneous transmissions over
the same port (Full-duplex), bandwidth was doubled. By reducing the collision domain to
a single switch-port, the need for carrier sensing was eliminated. And by using the
store-and-forward technology’s approach for inspecting each packet to intercept corrupt
or redundant data, unnecessary transmission was eliminated from the network. Switch
technology also employed address learning to replace the inefficient receiving port.
