2-1Chapter 2: Network PlanningIntroduction to SwitchingA network switch allows simultaneous transmission of multiple packets vianon-crossbar switching. This means that it can partition a network more efficientlythan bridges or routers. The switch has, therefore, been recognized as one of themost important building blocks for today’s networking technology.When performance bottlenecks are caused by congestion at the network accesspoint (such as the network card for a high-volume file server), the deviceexperiencing congestion (server or power user) can be attached directly to aswitched port. And, by using full-duplex mode, the bandwidth to the end-user can bedoubled to maximize throughput.A switch can be easily configured in any Ethernet network to significantly boostbandwidth while using conventional cabling and network cards.Sample ApplicationsVDSL provides significant savings on network installation, equipment and servicefees. Internet services operate over existing phone cabling and a minimal amount ofnetwork equipment. The only changes require installing an ES2002-TS CPE foreach client, and a VDSL Switch-VS2512A and VDSL Splitter-VM2524 in thebasement or wiring closet. Internet service can then be provided over a directEthernet connection to your ISP. For non-commercial environments, you can run theswitch through a broadband router at the customer’s site. This will allow you to use asingle-user account and ISP sharing to significantly reduce network access charges.Accton’s VDSL Switch-VS2512A provides Internet connections of up to 15 Mbps, fullduplex, for multiple users. Cable distances also can run up to 1525 meters (at lowertransmission rates). VDSL installation is extremely economical for multiple-tenantdwellings such as apartment buildings, hotels or school dormitories, as well ascommercial buildings.VDSL provides multiple-user access to the Internet with benefits including:• Internet services such as e-mail over faster connections than currently possiblewith other options such as cable modem or ADSL• Multimedia applications such as video and virtual gaming made available to thebroader public for the first time• Access to corporate intranets at speeds close to that available in the officeBoth local network applications and Internet services are supported for commercialenvironments.
