    ETWORK LANNING NTRODUCTION TO WITCHING 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.

  • Page 30: Application Examples

    | Network Planning HAPTER Application Examples PPLICATION XAMPLES The switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. ETWORK GGREGATION With 28 parallel bridging ports (i.e., 28 distinct collision domains), the switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

  • Page 31: Figure 7: Remote Connections With Fiber Cable

    | Network Planning HAPTER Application Examples EMOTE ONNECTIONS WITH IBER ABLE Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-ZX link up to 100 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

    | Network Planning HAPTER Application Examples VLAN C AKING ONNECTIONS This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.
