  • Page 29: Network Planning

    HAPTER ETWORK LANNING 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.

  • Page 30: Application Examples

    ETWORK LANNING Application Examples The TigerSwitch 10/100 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. Collapsed Backbone The TigerSwitch 10/100 is an excellent choice for mixed Ethernet and Fast Ethernet installations where significant growth is expected in the near future.

  • Page 31: Central Wiring Closet

    PPLICATION XAMPLES Central Wiring Closet With 26 parallel bridging ports (i.e., 26 distinct collision domains), this switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10BASE-T/100BASE-TX ports on the switch are providing 100 Mbps connectivity for up to 24 segments.

  • Page 32: Remote Connection With Fiber Cable

    ETWORK LANNING Remote Connection with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 100 Mbps multimode fiber (MMF) link can run up to 2 km, and a 100 Mbps single-mode fiber (SMF) link can run as far as 20 km. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, and a 1000BASE-LX (SMF) link can run up to 70 km.

  • Page 33: Making Vlan Connections

    PPLICATION XAMPLES Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group it belongs to. When using port-based VLANs, ports can either be assigned to one specific group or to all groups. Port-based VLANs are suitable for small networks.

  • Page 34: Using Layer 3 Routing

    ETWORK LANNING Using Layer 3 Routing 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. The Fast Ethernet Routing Switch provides 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.

  • Page 35: Connectivity Rules

    ONNECTIVITY ULES Connectivity Rules When adding hubs (repeaters) to your network, please follow the standard connectivity rules for Ethernet or Fast Ethernet. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
