• External Interface API
• Dynamic API
• Participate in service contracts
• Conduct training

IPNE Specifics

• Allow operational network devices to communicate
  through a simulated network
• Delays, packet drops of simulated network are
  evident to operational devices

• Simulated network is transparent to operational
  devices (works with most IP packets)

IPNE Applications

• Observe network behavior in complex environments
• Learn how applications and protocols behave in
  different situations
• Study behavior of protocols in development
• Analyze a network based on real traffic
  characteristics

5
Summary

• IPNE is a useful tool that allows operational
  protocols to communicate through a simulated
  QualNet network
• Works with most types of IP traffic (traffic
  originators are not aware of simulated QualNet
  network)
