Overview

Network design and analysis refers to the essential methods required to properly design a network. A properly generated network design provides the following benefits:

• Proper analysis of existing equipment for network installation.
• List of requirements for network installation.
• Proper configuration of network components for optimum cost savings.
• A flexible and adaptable network topology.
• Correct selection of network hardware and software.
• Documentation of the network for future enhancements and modifications.
• Migration path into future network technologies without redesign.
• A long network life-cycle.
• Interconnect paths and methods for multiple network architectures.
• User analysis and configuration of network resources for optimal use.
• Network management plan and methodology to reduce downtime and allow for maximum use of available resources.
• Expectations for performance, reliability, and usability.
• Optimal programming environment for network applications.
• Training needs for programmers, users, and network managers.
• Recurring expense forecasting and budgeting methods.
• Network support needs (programming, management, user support).
• Use of mathematical modeling tools to help insure the success of the network design and topology.
• Optimal design to prevent network congestion, queuing delay, and proper placement of routing and management resources on the network.

Unfortunately, many network administrators do not take the time to perform a network design and analysis. Instead, they rely exclusively on vendor recommendations. Network design and analysis involves much more than ordering hardware and software from a vendor. If you want to trust a vendor, that is your choice. However, few vendors are qualified network designers, and those who are do not offer this service free...
