Operator perspective on next-generation optical access for future radio access

Abstract: Toward 5G mobile systems for 2020 and beyond, aggressive studies on radio access networks (RANs) are underway. In 5G systems, the role of the small cell based RAN is important to provide 10 Gb/s class broadband and flexible services, and optimization of the optical access network to accommodate small cells is also important. To efficiently deploy and operate small cells, cooperation between mobile and optical access networks is essential. For the fixed network operator side, TDM-PON based mobile backhaul and fronthaul are preferable for its cost effectiveness. In this article, radio access and optical access technologies are briefly introduced, and TDM-PON based optical access techniques for future radio access are described.

Next-Generation Optically-Interconnected High-Performance Data Centers

Abstract: The communication requirements imposed by the unabated growth in both the size and computational density of modern data centers will soon outpace the fundamental capabilities of conventional electronic interconnection networks. Optical interconnects represent a potentially disruptive technology that can simultaneously satisfy the throughput, latency, and energy demands of these next-generation systems. In this paper, we propose an end-to-end photonic networking platform for future optically-interconnected data center networks. A reconfigurable hybrid photonic network building block and a protocol-agnostic optical network interface comprise the key elements of our proposed system. A modular optical switch fabric prototyping platform is designed and implemented to support a wide variety of potential photonic technologies. We successfully demonstrate nanosecond-scale optical packet-switching at 1-Tb/s per port (40-Gb/s ×25λs) through our prototype, configured as a 4×4 switch, and confirm error-free transmission across all wavelengths. In order to flexibly allocate appropriate bandwidth for heterogeneous applications, we further implement and evaluate a novel wavelength-reconfigurable optical packet- and circuit-switch by utilizing our optical switch platform. Finally, we detail our implementation of an optical network interface card (O-NIC) designed to bridge the gap between the well-established protocol layers utilized in current networks and the physical layer of the proposed photonic networks and demonstrate its functionality by the streaming of high-definition video through the end-to-end optical network.

System for operating an Ethernet data network over a passive optical network access system

Abstract: A data communications system which provides multiple logical channels on a passive optical network (PON) using subcarrier multiple access (SCMA). The PON includes multiple optical network units (ONU) which each communicate with a head-end over a logical channel. Collisions among upstream transmissions are thereby avoided and high speed Ethernet service over large distances is made possible.

Abstract: We report the first experiment of the OpenFlow architecture in flexible optical networks. Effective control of transmission performance is demonstrated through integrated correlation of statistics and monitoring information.

An XG-PON module for the NS-3 network simulator

Abstract: 10-Gigabit-capable Passive Optical Network (XG-PON), one of the latest standards of optical access networks, is regarded as one of the key technologies for future Internet access networks. In this paper, we propose and discuss the design and implementation of an XG-PON module for the NS-3 network simulator. The aim is to provide a standards-compliant, configurable, and extensible module that can simulate XG-PON with reasonable speed and can support a wide range of research topics. These include analysing and improving the performance of XG-PON, studying the interactions between XG-PON and the upper-layer protocols, and investigating its integration with various wireless networks.
