  • Page 10: Chapter 1: Introduction

    Chapter 1: Introduction Switching Technology The Ethernet Switch allows simultaneous transmission of multiple packets via an internal high-speed data channel. This means that it can partition a network more efficiently than bridges or routers in most environments. The Ethernet Switch is therefore fast being recognized as one of the most important building blocks for today’s networking technology.

  • Page 11: Accton's Smart Extender (The Fast Switchub-2S)

    SwitcHub-2s User’s Guide Accton’s Smart Extender (The Fast SwitcHub-2s) Accton’s Smart Extender can boost network bandwidth fourfold, depending on your configuration (i.e., if running at 100Mbps and full-duplex operation for both ports). It provides two 10/100 Mbps RJ-45 ports (set at full or half-duplex) to connect to either a subnetwork, or directly to a server or key workstation.
  • Page 12 SwitcHub-2s User’s Guide Traditional bridges and routers use a switching method called store-and- forward in which the entire frame must be received before the bridge can perform a table look-up for the destination node and forward the packet to the corresponding port.

  • Page 13: Features Of The Fast Switchub-2S

    SwitcHub-2s User’s Guide Features of the Fast SwitcHub-2s Conforms to the IEEE 802.3 and IEEE 802.3u specifications, as well as 10BASE-T and 100BASE-TX standards Provides two independent RJ-45 10BASE-T / 100BASE-TX Ethernet station ports, where each logical port consists of 1 MDI port (for connection to hubs or switches) and 1 MDI-X port (for connection to workstations or servers), eliminating the need for crossover cables Both ports support full-duplex and half-duplex operation...

  • Page 15: Chapter 2: Hardware Description

    Chapter 2: Hardware Description Accton’s SwitcHub-2s is a highly reliable network switch that complies with IEEE 802.3 (10BASE-T) and IEEE 802.3u (100BASE-TX) specifications. This switching hub delivers superior performance compared to the bridge and router solution, and at a much lower cost. By confining local traffic to the originating segment, and only forwarding cross-segment traffic to the other port, this hub meets the requirements for Ethernet and IEEE 802.3 networks.
