Evaluation Data Transfer in NS2

IEEE-1394b is a high speed data bus, which is widely adopted in various commercial products. Its isochronous data transfer is well suited for time critical data transfer, such as video and audio. However, rare work has been done for IEEE-1394b isochronous data transfer performance evaluation. This paper aims at giving an efficient way for IEEE-1394b isochronous data transfer performance evaluation. First, it gives an overview of IEEE-1394b isochronous data transfer, its bandwidth reservation mechanism and bus owner/supervisor/selector (BOSS) arbitration. Then, a detailed single node model of IEEE-1394b isochronous data transfer with deterministic and stochastic Petri net (DSPN) is proposed, which captures all relevant system aspects in a concise way. The proposed model was evaluated by simulation with TimeNet 4.0. The influences of several system parameters are illustrated. And the upper bound of bus utilization and packet arrival rate of single node bus are also obtained.
