  • Page 31: 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 32: Application Examples

    ETWORK LANNING Application Examples The SMC8748L2 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 SMC8748L2 is an excellent choice for mixed Ethernet, Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet installations where significant growth is expected in the near future.

  • Page 33: Network Aggregation Plan

    PPLICATION XAMPLES Network Aggregation Plan This switch provides 48 parallel bridging ports (i.e., 48 distinct collision domains), which can be used to 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 are providing 1000 Mbps connectivity through layer 2 switches.

  • Page 34: Remote Connections With Fiber Cable

    ETWORK LANNING Remote Connections with Fiber Cable 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.

    PPLICATION XAMPLES 10GBASE Fiber Connections The switch's 10GBASE modules provide a cost-effective way to build a 10 Gbps Ethernet network. A 10GBASE-SR (MMF) link can connect to a device up to 300 meters away, a 10GBASE-LR (SMF) link up to 10 km, and a 10GBASE-ER (SMF) link up to 40 km.

  • Page 36: Making Vlan Connections

    ETWORK LANNING Making VLAN Connections 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. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.

  • Page 37: Application Notes

    PPLICATION OTES Application Notes 1. 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. 2.
