Implementation and Simulation Results of Multiple Total Bandwidth Server Mechanism
Multiple servers as a mechanism for scheduling aperiodic tasks in heterogeneous environments can increase performance of real time systems. This paper describes implementation of the multiple total bandwidth server (MTBS) mechanism, a version of total bandwidth server (TBS) for distributed systems, in a simulation tool. The tool enables evaluation of the mechanism performance for arbitrary task sets and server parameters. Earliest deadline first (EDF) algorithm is used for scheduling periodic tasks. TBS is adjusted for use as a multiple server mechanism. Results of simulations show that by increasing the number of servers, aperiodic task response time is reduced ; periodic response time is also reduced while number of sent tasks changes insignificantly. In comparison with the previous results, TBS server proved to be superior.
