Client-Server Performance on Flow-Controlled ATM Networks :
A Web Database of Simulation Result

This web site reports on two results. First, extensive simulation has demonstrated the effectiveness of using credit-based ATM flow control in supporting client-server systems. In particular, the simulation has shown that request/response protocols used in these systems allow efficient sharing of switch buffer. Second, a Web database of simulation results covering more than 10,000 network and load configurations is available online. The web database approach has proven to be effective in managing and navigating a large set of simulation results.

Automatic Plotting of Client-Server Performance Curves


NC RS BS BPR BLP BDR
Plot Curve for:

Parameters:

NC: Number of clients in this experiment
RS: Server reply size in cells
BS: Buffer size, in cells, of the over-subscription input port of Switch 1
BPR: Background Peak Rate of the periodic square-wave traffic
BLP: Background Load Period, which is the length of the periodic square-wave cycle in cell cycles
BDR: Background Duty Ratio in each periodic square-wave cycle
