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 (CSMA/CD) protocol, and greatly reduced
unnecessary transmission.
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, it
replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex operation 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.
Auto-negotiation and flow-control may require disablement for some
networking operations that involve legacy equipment. Disabling the
auto-negotiation is accomplished by adjusting the speed or duplex operation
of a port.
Ethernet Switching Technology supplies higher performance at costs lower
than other solutions. Wider bandwidth, no congestion, and the reduction in
network traffic is why the use of an Ethernet switch is replacing expensive
routers and inefficient hubs as the best network solution.
