TL;DR: This paper articulate how the traditional optical networking research area of traffic grooming may be combined with recent advances in Internet architecture, specifically a proposed Future Internet architecture called ChoiceNet, and empowered by the recently emerged concept of software defined networking to make some key contributions to this problem.
Abstract: The problem of providing an agile, energy-aware, flexible optical network architecture is one of the challenges in optical networking in the coming decade. A key element in this challenge is the balancing of the benefits to customer and provider, and creating an agile system capable of reflecting both provider and customer interests on an ongoing basis as network conditions change. In this paper, we articulate how the traditional optical networking research area of traffic grooming may be combined with recent advances in Internet architecture, specifically a proposed Future Internet architecture called ChoiceNet, and empowered by the recently emerged concept of software defined networking, to make some key contributions to this problem.

TL;DR: In this scheme, variable-bit-rate VPN communications are achieved and based on optical sideband reuse at the ONU side and optical carrier suppression at the optical line terminal (OLT), the ONUs are source-free and components for the operation of frequency shift are eliminated.
Abstract: We propose and experimentally demonstrate a new orthogonal frequency division multiple access-based passive optical network (OFDMA-PON) architecture supporting flexible all-optical virtual private network (VPN) with source-free optical network units (ONUs). In our scheme, variable-bit-rate VPN communications are achieved. Moreover, based on optical sideband reuse at the ONU side and optical carrier suppression (OCS) at the optical line terminal (OLT), the ONUs are source-free and components for the operation of frequency shift are eliminated.

TL;DR: This paper introduces the recent efforts that have been devoted to the research supported by the STRAUSS project on SDN/Openflow controlled optical networks, and demonstrates the end-to-end flexible service provisioning over both nationwide and international testbeds with SDN orchestration via unified interface based on control orchestration protocol.
Abstract: Software-defined optical network has the combined benefit of both control flexibility and large transport capacity, thus having the potential of realizing a new ground-breaking optical network framework. In this paper, we introduce our recent efforts that have been devoted to the research supported by the STRAUSS project on SDN/Openflow controlled optical networks. The unified SDN control plane is able to configure the optical nodes/devices and thus the optical network through the cooperation of Openflow agents with more flexibility and optimization, thanks to its global knowledge of network resource and centralized controllability. Furthermore, we are able to interconnect our network with other heterogeneous multi-domain networks, while demonstrating the end-to-end flexible service provisioning over both nationwide and international testbeds with SDN orchestration via unified interface based on control orchestration protocol.

TL;DR: Simulation and experimental results demonstrate the proof of concept and show that the power consumption of the access/in-building network can be significantly reduced when the proposed cascaded bit-interleaving protocol is employed.
Abstract: This paper proposes and experimentally evaluates the Cascaded Bit-interleaving architecture and protocol, an energy-efficient solution that aims to reduce the power consumption of integrated optical access/in-building networks, while offering high-speed Internet service to end-users. In the new architecture, optical-electrical-optical (OED) regeneration is employed at the interface between the access and in-building networks, and downstream frames are generated at the central office using the two-stage bit-interleaving scheme. The users' network nodes only process the data destined for them without any buffering at a lower clock rate than the aggregate PON rate, thereby significantly reducing their energy consumption. Simulation and experimental results demonstrate the proof of concept and show that the power consumption of the access/in-building network can be significantly reduced when the proposed cascaded bit-interleaving protocol is employed.
