Switching Technology 
Another approach to pushing beyond the limits of Ethernet 
technology is the development of switching 
technology. A switch bridges Ethernet packets at 
the MAC address level of the Ethernet protocol 
transmitting among connected Ethernet or Fast 
Ethernet LAN segments. 
Switching is a cost-effective way of increasing the total network 
capacity available to users on a local area 
network.  A switch increases capacity and 
decreases network loading by dividing a local 
area network into different segments, which don’t 
compete with each other for network transmission 
capacity. 
The switch acts as a high-speed selective bridge between the
 
individual segments.  The switch, without 
interfering with any other segments, 
automatically forwards traffic that needs to go 
from one segment to another.  By doing this the 
total network capacity is multiplied, while still 
maintaining the same network cabling and adapter 
cards. 
Switching LAN technology is a marked improvement over the 
previous generation of network bridges, which 
were characterized by higher latencies.  Routers 
have also been used to segment local area
