Ethernet
Switching - Ethernet Switches
switched ethernet
is an Ethernet network that is controlled by a switch. Ethernet is wired
in a star configuration with a
hub or switch in
the middle.
Hubs, which predated switches, are shared media devices.
All stations attached to the hub share the total bandwidth. Switches provide
each sender and receiver pair with the full bandwidth and are significantly
faster than hubs (see switched Ethernet). Like the client machines, Ethernet
switches and hubs also support 10/100 and 10/100/1000 speeds.
The switch cross connects two
stations and gives each sender-receiver pair the full bandwidth of the network.
The total bandwidth is 20 Mbps or 200 Mbps between nodes for full-duplex
operation or 10 and 100 for half-duplex. A major advantage in migrating from
shared to switched Ethernet is that only the hub is replaced with an Ethernet
switch. The existing network adapters (NICs) in every computer connected to the
switch are still valid.
A 10/100 Ethernet port supports two speeds: 10 Mbps (10BaseT) and 100 Mbps
(100BaseT).
Computers also come with
10/100/1000 ports, which adds
Gigabit Ethernet at one gigabit per
second. Gigabit Ethernet (GigE) is commonly used as a high-speed link between
switches and servers. Ethernet devices negotiate with each other and transmit at
the highest speed possible. However, if a 100 Mbps switch is communicating with
a 10 Mbps client, the slower speed is used.
