The industry-wide shift from Ethernet hubs to Ethernet switches has dramatically boosted the
bandwidth of networks and helped to eliminate congestion problems inherent with the CSMA/CD
protocol (Carrier Sense Multiple Access with Collision Detection). Since a switch operates by
learning the location of addresses and forwarding messages directly, unnecessary traffic is
greatly reduced. It will use auto-negotiation to regulate the speed and duplex of each port based
on the capabilities of connected devices. These features combine with flow control allow a 100M
node to effectively communicate with a 10M node without losing data. Connecting one device
per switch port also allows two-way, simultaneous transmission to occur (full duplex), essentially
doubling the bandwidth. Further, by segmenting a collision domain in this way, the need for
non-deterministic carrier sensing (CSMA/CD) is eliminated. The utilization of a store-and-forward
switching algorithm allows each packet to be inspected, and corrupt or redundant data to be
filtered, further eliminating unnecessary traffic that often slows a network down.
