  • Page 33: Network Planning

    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. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.

  • Page 34: Application Examples

    | Network Planning HAPTER Application Examples PPLICATION XAMPLES The Gigabit Ethernet Switches are not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs or IP subnets. Some typical applications are described below. OLLAPSED ACKBONE The Gigabit Ethernet Switches are an excellent choice for mixed Ethernet, Fast...

  • Page 35: Figure 8: Network Aggregation Plan

    | Network Planning HAPTER Application Examples ETWORK GGREGATION With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), a Gigabit switch stack can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches.

  • Page 36: Figure 9: 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 5 km, and a 1000BASE-LH link up to 70 km. This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 37: Figure 10: Making Vlan Connections

    | Network Planning HAPTER Application Examples VLAN C AKING ONNECTIONS These switches support 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.

  • Page 38: Figure 11: Ip Routing For Unicast Traffi

    | Network Planning HAPTER Application Examples SING AYER OUTING VLANs can significantly enhance network performance and security. However, if you use conventional routers to interconnect VLANs, you can lose most of your performance advantage. These Gigabit Ethernet Switches are routing switches that provide wire-speed routing, which allows you to eliminate your conventional IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN.

    | Network Planning HAPTER Application Notes PPLICATION OTES Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode.
