Campus Network Design Principles and NREN Models

This is generally one day of discussion as part of a larger Campus Network Design program.

Layer 2 (switching) that is part of a larger training program. To support this day of training the following topics may precede:

  • Layers 1/2/3 Refresher

Target audience

Network system administrators, engineers and technicians from RENs and Universities who are responsible for network maintenance, planning and design.


  • Basic knowledge of TCP/IP networking
  • For most workshops participants are asked to bring a laptop

Campus Network Design Best Practices

  • What problems are we trying to solve?
    • Network design goals
    • Reliability
    • Resiliency
    • Manageability
    • Scalability
    • Layering

  • Research and Education Networks
    • Why an REN
    • Models of RENs
    • IP addressing and NAT

  • How to plan IP address management from the beginning to accommodate growth
  • How to segment different areas of the LAN with IP subnets
  • Network addressing strategies
  • NAT or not
  • Need to be able to aggregate

Hierarchical design building blocks

  • Build star networks
  • Separate core and edge functions
  • Route in core and switch at the edge
  • Develop and use standard building blocks
  • Have a strategy that allows incremental growth

Physical Cabling Infrastructure

  • Cable types
  • Copper cabling systems
  • Fiber Optic Systems
