Analytical model for the IPACT dynamic bandwidth allocation algorithm for EPONs

Thorough analysis of the IPACT dynamic bandwidth allocation algorithm for EPONs

This paper describes extensive research in the field of the Multipoint Control Protocol (MPCP) for the Ethernet Passive Optical Network (EPON). More in particular the dynamic bandwidth allocation (DBA) algorithm IPACT (Interleaved Polling with Adaptive Cycle Time) is analytically modeled. The main focus has been on analyzing cycle times and packet delay in detail. The analysis starts from a simple traffic model with Poisson arrival rates, symmetric load and fixed packet size. Based on the obtained insights, more general cases with asymmetric traffic load, packet size distribution, self-similar traffic and differentiated services are further elaborated
