Chapter 2: Network Planning

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via 
non-crossbar switching. This means that it can partition a network more efficiently 
than bridges or routers. The switch has, therefore, been recognized as one of the 
most important building blocks for today’s networking technology.

When performance bottlenecks are caused by congestion at the network access 
point (such as the network card for a high-volume file server), the device 
experiencing congestion (server, power user, or hub) can be attached directly to a 
switched port. And, by using full-duplex mode, the bandwidth of the dedicated 
segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end 
stations is limited by a maximum hop count. However, a switch turns the hop count 
back to zero. So subdividing the network into smaller and more manageable 
segments, and linking them to the larger network by means of a switch, removes this 
limitation.

A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet 
network to significantly boost bandwidth while using conventional cabling and 
network cards.
