Differentiated Services: an Experimental vs. Simulated Case Study
This work addresses the need for reliable simulation tools in networking research, though it is incremental as it focuses on validating existing methods rather than introducing new ones.
The paper tackled the problem of verifying simulation accuracy for advanced networking studies, specifically for the Differentiated Services (DiffServ) architecture, by comparing experimental results from a real network with simulation outcomes, leading to useful suggestions for a more critical approach to such simulations.
This paper aims to provide a proof of concept of the accuracy of simulations for advanced networking study. The particular target technology is the Differentiated Services (DiffServ) architecture. The method has been to apply experimental activities conducted in a real network to a simulation environment, to gather the same performance parameters and to compare results. A worthy re-engineering of the DiffServ module of the deployed software program has been carried out and significant contribution have been made to overcome the encountered limitations and to enrich its modeling capabilities. Final results give useful suggestions for a more critical approach to simulations targeted for advanced networking study.
