technology and digital signal processing that will enable
Gigabit Ethernet to eventually operate over unshielded
twisted-pair (UTP) cabling, outfitting your network with a
powerful 1000Mbps-capable backbone/server connection
creates a flexible foundation for the next generation of
network technology products.
Switching Technolog
Another key development pushing the limits of Ethernet
technology is in the field 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 making it possible for a local area
network to be divided into different
segments
which don’t
compete with each other for network transmission
capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between
the individual segments. Traffic that needs to go from one
segment to another (from one port to another) is
automatically forwarded by the switch, without
interfering with any other segments (ports). This allows
the total network capacity to be multiplied, while still
maintaining the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch
is an effective way of eliminating problems of chaining
hubs beyond the “two-repeater limit.” A switch can be used
