A Universal Simulator?
a single simulation environment used by the entire networking simulation community to facilitate model reuse
standardized definition of interfaces between model components still required
which one?
- no one simulation package is universally accepted today
- different products have different strengths and weaknesses
can one simulation approach satisfy all user requirements?
flexibility to incorporate new advances in simulation technology?
what about legacy models?
A single simulation system may not be sufficiently general to adequately support all of the requirements of the networking community
