Overview

Network design and analysis refer 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 ensure 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 involve 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...
