A network architecture that integrates several WDM PON access segments in a metropolitan area network and uses optical circuit/burst switching is presented here. This architecture targets the delivery of very high speed end to end optical communications between the edge nodes connecting the end users. The combination of circuit switching and burst transmission allows the simultaneous delivery of real-time applications (VoIP, Video) and other data-oriented applications (Internet, peer-to-peer). In the proposed architecture there is a clear separation of the functions in a data plane and a control plane. A centralized control entity manages the overall architecture. A dedicated aggregation node acts as a gateway to external networks. After a presentation of the proposed network architecture, this paper focuses on the performance evaluation of the control plane using simulation. Our results show that the queuing delay remains acceptable even under heavy traffic loads.

“…Interaction between TCP based traffic and the DBA employed in MAC layer of 10GE-PON was also studied in [12]; yet the scope of the analysis was restricted to single congestion control based tests, with more focus placed on TCP based traffic only in the presence of multiple ONUs, without provisioning sufficient buffer at relevant nodes. In [13], the authors analysed the effect of ONU buffers and TDMA Frame duration, for GPON, using single ONU and generic TCP; however, the same authors had also agreed that further analysis should be done with high-speed TCP variants for GPON MAC layer, using multiple competing TCP flows to better understand TCP performance over GPON.…”

Abstract-XG-PON is the next-generation standard for passive optical networks operating at 10Gb/s and TCP is the dominant transport protocol of the Internet. In this paper, we present the first performance evaluation of TCP over XG-PON, considering efficiency, fairness, responsiveness, and convergence. The impact of XG-PON's large delay-bandwidth product and asymmetric bandwidth provision are assessed, together with the dynamic bandwidth allocation mechanism. Our state-of-the-art NS3 simulation uses real implementations of three TCP variants (Reno, CUBIC and H-TCP) from the Network Simulation Cradle. Our results highlight several issues that arise for TCP over XG-PON, and emphasise the need for improved awareness of medium access control and scheduling in the context of specific TCP congestion control behaviour.

“…To the best of our knowledge, TCP performance over PON networks has been the subject of few papers [16][17][18], and these have all focused on IEEE EPON systems. For GPON systems, only [19] aims at assessing the impact that the GPON MAC layer may have on TCP. In [19] the authors report a preliminary study of TCP performance issues that may arise in GPON networks.…”

“…For GPON systems, only [19] aims at assessing the impact that the GPON MAC layer may have on TCP. In [19] the authors report a preliminary study of TCP performance issues that may arise in GPON networks. This paper has two aims: first, to show methods to simultaneously measure throughput and physical line capacity in very wide broadband GPON accesses, and second, to illustrate how to overcome the throughput limitations because of TCP.…”

Multilevel bandwidth measurements and capacity exploitation in gigabit passive optical networks

et al. 2014

The authors report an experimental investigation on the measurement of the available bandwidth for the users in gigabit passive optical networks (GPON) and the limitations caused by the Internet protocols, and transfer control protocol (TCP) in particular. We point out that the huge capacity offered by the GPON highlights the enormous differences that can be showed among the available and actually exploitable bandwidth. In fact, while the physical layer capacity can reach value of 100 Mb/s and more, the bandwidth at disposal of the user (i.e. either throughput at transport layer or goodput at application layer) can be much lower when applications and services based on TCP protocol are considered. In the context of service level agreements (SLA) verification, we show how to simultaneously measure throughput and line capacity by offering a method to verify multilayer SLA. We also show how it is possible to better exploit the physical layer capacity by adopting multiple TCP connections avoiding the bottleneck of a single connection.
