Research Issues and Other Challenges
Calibration, validation, and scaling: how to emulate different speed networks? Scaling behavior of emulating faster links by slowing nodes?
Can we sufficiently capture real router internal behavior in a PC?
Assuring validity: detecting switch bottlenecks, measuring and controlling physical characteristics without introducing artifacts.
Algorithms and software to map requirements to resources while minimizing artifacts.
Providing a reasonable user interface to all this.
