Lesson 14 – DESIGNING A NETWORK

Assessing Network needs Meeting Network needs OVERVIEW

Considerations Applications User requirements Network services Security and safety Growth and capacity planning ASSESSING NETWORK NEEDS

Storage space Bandwidth Network services Budget Considerations

Word processor Spreadsheet End-user database Presentation graphics Personal information manager Virus-scanning software Office suites Applications

Which applications do employees require? Do they need the entire suite? What about file creation/sharing? Applications

Department-specific applications: Accounting Distribution and inventory control Manufacturing/MRP Information Technology Electronic commerce Human Resources Applications

Department-specific applications: Payroll and Stock Administration Publishing Marketing support Legal Line-of-business applications Applications

User requirements

File and print Backup and restore Web browsing FTP and Telnet Internet/external Internet security Dial-out to/from LAN via modem pool Network services

Fax into LAN Dynamic Host Configuration Protocol (DHCP) Centralized virus protection WAN services Streaming Internet radio/other media Voice over IP (VoIP) Network services

Storage and bandwidth requirements for each service. Other impacts the services will make. Network services

The company’s need to keep information secure. The importance of safety/security issues to the company. Security and safety

Impact of growth on parts of the Network. Application behavior. Network operating systems, Network topologies, and client/server computers. Growth and capacity planning

Choosing Network type Choosing Network structure Choosing servers MEETING NETWORK NEEDS

Ethernet: 10Base-T 100Base-T Choosing Network type

Tips: Consider Ethernet’s CSMA/CD collision handling. Use “home run” wiring. Have a Network backbone. Choosing Network structure

Tips: Use inexpensive Ethernet switches as hubs Consider the building. Run the backbone vertically from floor-to-floor for multi- floor buildings. Choosing Network structure

Tips: Run backbone speed at 10 times the hub/desktop Network speed. Keep server and node on the same segment Connect servers directly to the backbone’s Ethernet switch. Choosing Network structure

Tips: Separate high-bandwidth users. Monitor the ratio of collision packets to data packets. Use subnets. Keep resources close to users. Choosing Network structure

Choosing servers

More small servers : Host fewer services more reliably than fewer large servers hosting many services. Increase chances of server failure. Are expensive. Require more maintenance. Choosing servers

While using more than one server, consider: Which services should be redundant on another server. How you will deal with server failure. Small number of large servers or large number of small servers. Choosing servers

Assessing Network needs: Applications User requirements Network services Security and safety SUMMARY

Meeting Network needs: Choosing Network type Choosing Network structure Choosing servers Summary
