Analysis and simulation of a delay-based service differentiation algorithm for IPACT-based PONs

Managing delay in the access

“…This strategy favors the creation of short HP cycles and long LP cycles, with a predefined ratio between them. In this paper we showed simulation results of this idea, fully developed in [13]. Then we introduced un upper bound on the HP cycle times in order to set a hard limit to HP traffic delay, and analysed its impact on LP traffic loss.…”

“…This new algorithm forces the transmission of high-priority traffic more often than low-priority one such that the expected average cycle time for high-priority packets is much smaller (and also proportional and configurable) than for low-priority ones. A complete explanation of this algorithm and the proposed analytical model can be found in [13] We shall start by reviewing the formulae ruling delay in regular IPACT in the next section.…”
