Performance analysis of leaky bucket policing with priority management on ATM networks

In this paper, we introduce the selective discarding priority management scheme, partial buffer sharing (PBS), to leaky bucket policing on ATM networks, to guaranty lower loss probability for high priority cells. The performance of the priority leaky bucket (PLB) is analyzed using an extended fluid flow method. The service assumed to be a bursty traffic which can be modeled as superposition traffic of M homogeneous on-off sources. The results of analysis and simulation experiments show that this scheme is useful. From the performance analysis results we may get suitable PLB parameters for efficient control
