Interleaved polling with adaptive cycle time
In this article, we will explore the impact of Interleaved polling with adaptive cycle time on different aspects of society. From its influence on popular culture to its relevance in history, Interleaved polling with adaptive cycle time has left an indelible mark in various spheres of life. Over the years, Interleaved polling with adaptive cycle time has been the subject of debate and analysis, generating all kinds of opinions and theories. Through this study, we seek to shed light on the importance of Interleaved polling with adaptive cycle time and its role in shaping the world as we know it. By exploring its implications and consequences, we hope to delve into the complexity of Interleaved polling with adaptive cycle time and its lasting influence.
Interleaved polling with adaptive cycle time (IPACT) is an algorithm designed by Glen Kramer, Biswanath Mukherjee and Gerry Pesavento of the Advanced Technology Lab at the University of California, Davis in 2002.[1] IPACT is a dynamic bandwidth allocation algorithm for use in Ethernet passive optical networks (EPONs).
IPACT uses the Gate and Report messages provided by the EPON Multi-Point Control Protocol (MPCP) to allocate bandwidth to Optical Network Units (ONUs).[2] If the optical line terminal grants bandwidth to an ONU and waits until it has received that particular ONU's transmission before granting bandwidth to another ONU, then time equivalent to a whole messaging round-trip is wasted during which the upstream may remain idle. IPACT eliminates this idle time by sending downstream grant messages to succeeding ONUs while receiving transmissions from previously granted ONUs. It accomplishes this by calculating the time at which a transmission grant allocated to a previous ONU ends.
