“…Further, exploring combined circuit and packet service in long-reach PONs with very long round trip propagation delays, which may require special protocol mechanisms, see e.g., [101]- [103], is an open research direction. Another direction is to examine the integration and interoperation of circuit and packet service in the PON access network with metropolitan area networks [104]- [109] and wide area networks to provide circuit and packet service [32].…”

“…One direction is to examine DBA approaches providing specific quality-of-service assurances to some traffic classes, while providing overall low average delays to best effort traffic. Another direction is to examine efficient approaches for interfacing long-reach PONs with complementary networks, such as wireless local and access networks [56]- [59] as well as metropolitan and wide-area networks [60]- [63].…”

Abstract-Multi-thread polling (MTP) with offline scheduling and offline excess bandwidth distribution has recently been proposed to overcome the long propagation delay of long-reach passive optical networks (LR-PONs). In this paper, we propose a complementary MTP approach with online scheduling and online excess bandwidth distribution. We evaluate the throughput-delay performance of offline and online MTP against offline and online singlethread polling (STP) with excess bandwidth distribution as well as double-phase polling (DPP) with excess bandwidth distribution. We find that online MTP and STP as well as DPP give significantly lower average packet delays than offline MTP.Index Terms-Delay evaluation, dynamic bandwidth allocation, excess bandwidth distribution, long-reach PON (LR-PON), multithread polling (MTP).

Abstract-The increased propagation delay of future longreach passive optical networks (LR-PONs) may lead to a significantly increased idle time and delay if optical network units (ONUs) use conventional report-grant mechanisms. Sophisticated and efficient bandwidth allocation mechanisms are required to cope with the imposed propagation delay in LR-PONs. In this study, we evaluate three dynamic bandwidth allocation (DBA) frameworks in terms of frame (packet) delay; namely, we consider conventional (interleaved) polling for traditional PON and two recently introduced scheduling paradigms for next generation LR-PON, i.e., multi-thread polling (MT-P) and real-time polling (RT-P). We enhance MT-P and RT-P by applying the justin-time framework. Next, we provide an analytical framework for evaluating the end-to-end frame delay in our enhanced MT-P and RT-P frameworks. We compare their performance with conventional polling and double-phase polling and investigate their shortcomings and advantages in an LR-PON setting. The simulation results closely match the analysis for this framework. Also, our results indicate that RT-P significantly reduces frame delay in LR-PONs compared to MT-P and conventional polling frameworks.
