  1. Designing a Network COMP 315

  2. Choosing Desktop Computers • Apoyar dos o másplataformas de computadorasesproblemático. Considere lo siguiente: • Necesidad de tener expertise en variasplataformas • Necesidad de tener en “stock” piezas de equiposdiferentes • Necesidad de tenervariaslicencias e inventario de software • Incompatibilidad • Limitación en la programación a desarrollar

  3. Aspectos a considerar • Confiabilidad y servicio • Precio y ejecutoria

  4. Requerimientos de un “Network Workstation” • Hardware • NIC (network interface card) • Cables • conectores • Network workstation software

  5. Accesandolasnecesidades del network • ¿Cuánto espacio de almacenamiento se requiere? • ¿Cuánta capacidad de la línea de transmisión (bandwidth) se requiere? • ¿Qué servicios ó aplicaciones se requieren? • ¿Cuál es el presupuesto del proyecto?

  6. Aplicaciones • Word processor • spreadsheet • End-user database • Presentation graphics • E-mail • Personal information manager • Virus-scanning software

  7. Aplicaciones por Departamentos • Accounting • Distribution and inventory control • Manufacturing /MRP • Information technology • Electronic commerce • Human resources • Payroll and stock administration • Publishing • Marketing support • Legal • Other line-of-business applications specific to the company’s industry

  8. Usuarios • Bandwidth requirements • Storage requirements • Service requirements

  9. Network services • File and print services • Backup and restore services • Internet web browsing • FTP and Telnet • Internet or external e-mail • Internet security services • Dial-out from LAN through a modem pool • Dial-out to LAN through a modem pool • Fax into LAN • Dynamic host configuration protocol (DHCP) services • Centralized virus-protection services • WAN services to other locations • streaming internet radio and other media • Voice over IP (VoIP)

  10. Security and Safety • Need to keep information secure – both inside and outside a company- and to keep the company’s data safe from loss

  11. Growth and Capacity Planning • A network designed for a rapidly growing company looks different from one for a slowly growing company, even if both companies start out at the same size.

  12. Meeting Network Needs • Choosing Network Type • Ethernet is by far the most common type of network installed today • For wiring to the desktop, you should choose 100Base-T • For your network backbone, you can usually use a higher-bandwidth connection, such as 1000Base-T

  13. Choosing Network Structure • Ethernet’s CDMA/CD collision handling means that an Ethernet network will handle only about one-third of its rated speed. • Except in the smallest networks, plan on a network backbone to which the hubs connect. • The physical building might dictate how you structure your network. • Consider running the backbone speed at 10 times the hub/desktop network speed.

  14. Choosing servers • NOS (network operating system) • PC-centric networks • Novell Netware 5 or Windows 2000 Server
