Galileo: a Tool for Simulation and Analysis of Real-Time Networks E. Knightly and G. Ventre International Computer Science Institute Berkeley, CA April 1992 Galileo is a flexible tool for simulation of heterogeneous real-time communication networks and for development and verification of network protocols. Galileo provides several unique features that make it particularly suitable for the simulation and analysis of networks that provide quality-of-service guarantees. First, its object-oriented programming environment provides the means for a modular, hierarchical, heterogeneous description of networks. Second, its multimedia device interface provides the tools for a qualitative analysis of network protocols. Finally, Galileo's network interface provides interaction with actual networks to access real data and simulate realistic multimedia scenarios.
