General Aspects

• Independence of demonstrator hardware

  • Availabiltity only within final phase
  • Isolate demonstrator (hardware) specifc side effects
  • Unknown flavors of TCP

• Analysis of “large” networks

• Adaptation to emerging project constrains

• Simulation tool: OPNET modeler / radio

  • Industry prooven
  • ATM support
  • Satellite Orbits can be included
  • Project specific aspects

Isolate demonstrator hardware-sepecific side-effects
might not be able to run in „real-time“

IP over ATM available

Unknown TCP flavors:
Until final definition of demonstrator hardware and operating system used, available TCP flavor was unknown.

Simulation tool:
Berkley‘s NS othter widely spread simulation tool (not usable for us, no ATM, restricted satallite support)

Opnet used by ,e.g., Nortel Networks, within DoD founded projects
STK has interface to Opnet
DLR uses Opnet for MAC development & simulation
