“…To the best of our knowledge, the only other implementation of a DBA in software is the work from NTT. In [31], the authors present a softwarebased implementation of an E-PON system, showing line-rate throughput performance for 1G EPON. In [9], their architecture was extended to a Flexible Access System Architecture (FASA), where the system can dynamically change the DBA running in the PON.…”

This paper presents the concept of virtual DBA, a method we propose to virtualize upstream capacity scheduling in PONs, which provides multiple independent virtual network operators with the ability to precisely schedule their upstream traffic allocation. After a brief introduction on the evolution of access network sharing, we present our virtual DBA architecture, detailing its main components. We then provide a summary of the work done in this area both from theoretical and practical implementation perspectives. In this paper, we propose a novel stateless algorithm for merging multiple independent virtual bandwidth maps based on priority classes and analyze its performance in terms of efficiency of capacity allocation and latency. Through our results we discuss the existence of a trade-off between traffic load and grant size distribution vs. efficiency and latency. We find that, differently from residential single-tenant application, when PONs are used for low latency and multi-tenant applications, the system has better overall performance if grants are allocated in small size. In addition, our analysis shows that for high priority, strict latency services, our proposed merging algorithm presents delay performance that is independent of the traffic distribution considered.

“…2. We used the same software architecture as our previous study [3] for implementing OLT‐specific functions running on the server. In detail, we use a data plane development kit to realise low jitter transmission/reception of MPCP messages in the server, and the smoothing round trip time between the server and ONU technique to compensate measurement jitter.…”

First demonstration of commodity L2 switch‐based passive optical network

The 'commoditisation' (i.e. using commodity hardware or commodity device as a hardware platform for network equipment) and 'softwarisation' (i.e. implementing the network function of the target equipment by software) have recently become big trends among communication carriers struggling to balance cost-efficiency and service flexibility. Especially in optical access networks, the concept of the commodity layer 2 (L2) switch-based passive optical network (PON) is attracting attention, but performance demonstrations have not been reported. This Letter offers the first performance demonstration of the L2 switch-based gigabit ethernet PON prototype constructed with an L2 switch and software-based PON-specific functions. The prototype achieves nearly 1 Gbps throughput in one-way transmission. Moreover, an additional numerical analysis confirms that the authors proposed architecture can accommodate sufficient PON port number.
