[. . . ] 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 maximum distance between end stations is limited. For Ethernet, there may be up to four hubs between any pair of stations; for Fast Ethernet, the maximum is two. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation. A switch can be easily configured in any Ethernet or Fast Ethernet network to significantly boost bandwidth while using conventional cabling and network cards. 2-1 NETWORK PLANNING Sample Applications 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. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just cascade the TigerSwitch to an Ethernet or Fast Ethernet hub or switch, or link to another workgroup using a Gigabit connection. In the figure below, the TigerSwitch 10/100 is operating as a collapsed backbone for a small LAN. It is providing dedicated 20 Mbps full-duplex connections to workstations and 200 Mbps full-duplex connections to power users and servers. . . . Servers 200 Mbps Full Duplex . . .

Collapsed Backbone 2-2 NETWORK PLANNING Central Wiring Closet With up to 52 ports on the switch, the TigerSwitch 10/100 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 TigerSwitch are providing 100 Mbps connectivity for up to 48 segments through SMC's TigerStackTM II 10/100 hubs. In addition, the switch is also connecting servers at 200 Mbps. TigerSwitch 10/100 TigerStack II 10/100 Stack Server Farm . Central Wiring Closet . . . 2-3 NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type (up to 2 kilometers for 100 Mbps fiber at full duplex, or up to 550 meters for 1 Gbps fiber). The TigerSwitch can serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The 100 Mbps fiber modules (with two ports per module) can be used to interconnect remote Fast Ethernet segments. While the Gigabit module can be used for a high-speed connection between floors in the same building, or to connect to other buildings in a campus setting. The figure below illustrates a TigerSwitch connecting multiple segments with fiber cable.

Collapsed Backbone Using Fiber Cable 2-4 NETWORK PLANNING 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 any number of groups. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing). When you expand port-based VLANs across several switches, you need to make a separate connection for each VLAN group. [. . . ] CSMA/CD Carrier Sense Multiple Access/Collision Detect is the communication method employed by Ethernet and Fast Ethernet. End Station A workstation, server, or other device that does not act as a network interconnection. Glossary-2 GLOSSARY Ethernet A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable. Fast Ethernet A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method. [. . . ]
