The design of a new hybrid Java simulator called Hybrid Network Simulator (HNS) was described. HNS simulates the movement of workload in queueing network where transactions may be of two types: traditional discrete transactions and continuous (fluid) transactions, which arrives discretely at the network traffic flows, and each discrete arrival carries a workload. The simulator admits models with both discrete and continuous traffic flows, and collects detailed statistics for both, including arrival, loss, buffer contents, departure, and delay statistics. Incorporation of Infinitesimal Pertrubation Analysis (IPA) derivative into HNS would provide a tool to assess their efficacy.
