Module 02: Network Design Fundamentals

• Overview of network design needs
• Describe key product groups for campus, WAN, data centre, security

Doing the Research

• Who is the customer?
  • Business
  • What sets them apart
  • What design will meet with their approval
• Understanding your customer is key to a successful network design
  • What are the business requirements and goals?
  • What is the state of the current network?
  • Analyse the current and future behaviours

The business requirements and goals might change as the network is being designed, so the process of research is cyclical.

Engaging with the Customer

Become a partner with the company. Understand the company as the managers do, to understand their overall goal. Learn the risks and consequences for failure.

Compare interaction with the customer to a game of Pong. There is lots of back and forth, which eventually results in 100% satisfaction with the network plan.

The lifecycle is continuous; feedback from the ‘operate’ phase feeds back into the next design phase.
