ETHERNET SWITCHES



ETHERNET SWITCHES
Ethernet switches, also known as bridges, are basic building blocks of networks, and are
so commonly used that you may not give them a second thought. It’s possible to build
networks without knowing very much about how switches work. However, when you
build larger network systems, it helps to understand both what goes on inside a switch
and how the standards make it possible for switches to work together.
Ethernet is used to build networks from small to large, and from simple to complex.
Ethernet connects your home computers and other household devices; switches for
home networks are typically small, low cost, and simple. Ethernet also connects the
Internet worldwide, and switches for Internet Service Providers are large, high cost, and
complex.
Campus and enterprise networks often use a mix of switches: simpler and lower-cost
switches are usually found inside wiring closets and used to connect devices on a given
floor of a building; larger and higher-cost switches are found in the core of the network
and are used to connect all the building switches together into a larger network system.
Data center networks have their own special requirements, and typically include high
performance switches that can be connected in ways that provide highly resilient
networks.
According to industry estimates, the worldwide market for enterprise switches recorded
revenues of over $5 billion per quarter in 2012, with total revenues exceeding $20 billion
for the year. For the second quarter of 2012, there were 55 million Gigabit Ethernet ports
shipped, and 3 million 10-Gigabit ports. At that rate, over 230 million enterprise switch
ports were sold in 2012. Aside from the enterprise market, there were annual revenues
of roughly $14 billion for service provider switches, resulting in total Ethernet switch
revenues of roughly $34 billion for 2012. To satisfy the large and ever-increasing market
for Ethernet switches, there are many varieties of switches offered at many price points.
The many kinds of switches and the many features that can be found in those switches
are both very extensive topics. Covering the entire range of technology and the various
ways switches can be used in network designs would require an entire book, or even
