Chapter 4: Network Planning
4. Network Planning
4.1 Introduction to Switching
A network switch enables simultaneous transmission of multiple packets, and it can partition a network more efficiently than
bridges or routers. The switch is one of the most important devices for today’s networking technology.
When performance bottlenecks are caused by congestion at the network access point such as a file server, the device can be
connected 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 can subdivide the network into smaller and more manageable segments, linking them to the larger network so
the hop count resets to zero and removes the limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly increase bandwidth
while using conventional cabling and network cards.
4.2 Application Examples
The LGB5028A and LGB5052A have 28 or 52 Gigabit Ethernet TP ports with Auto MDI-X and 4 slots for removable SFP
modules that support comprehensive types of fiber connection, such as LC and BiDi-LC modules. The switch is not only designed
to segment your network, but also to provide a wide range of options in setting up network connections. Typical
applications are described below.
Use the switch for the following applications:
• Remote site application in Enterprise or SMB.
• Peer-to-peer application in two remote offices.
• Office network.
• High-performance requirement environment.
• Advanced security for network safety applications.
• Data/voice and videoconference applications.
