TL;DR: The changing nature of data center networks and the role played by optoelectronics in future network designs are reviewed and industry roadmaps for bandwidth, port density, and scalability of optical links will be presented.
Abstract: In this invited tutorial paper, we review the changing nature of data center networks and the role played by optoelectronics in future network designs. Conventional network protocols will be reviewed, including Ethernet, Fibre Channel, and InfiniBand, and requirements for WAN connectivity between data centers. The transition to converged networks based on lossless Ethernet will be discussed, including FCoE and RoCE protocols. Industry roadmaps for bandwidth, port density, and scalability of optical links will be presented, and optical transceiver form factors including QSFP, CFP, and active optical cables will be discussed. The role of software defined networking (SDN) in next generation data center networks will also be presented in this context.

TL;DR: A new MAC is proposed that turns a PON system to be a slotted one when the system is operating in light load state and a Markov model is presented for the system to reduce power consumption.
Abstract: Ethernet Passive Optical Network (EPON) has become an important access network for realizing FTTX. Due to its broadcast nature in EPON, each Optical Network Unit (ONU) needs to examine every downstream frame delivered from Optical Line Terminal (OLT) to determine whether the frame is destined to it or not. This results in a waste of energy for all ONUs in a PON system. To reduce power consumption, we propose a new MAC that turns a PON system to be a slotted one when the system is operating in light load state. By doing so, an ONU can turn off its transmitter, receiver, and even part of the MAC controller to reduce power consumption. We present a Markov model for the system. Numerical results reveal that an ONU can still have 20 Mbps bandwidth even if only 3% of its time is in working state.

TL;DR: In this paper, the impact of impairments introduced by transparent elements present in the network, such as OADM and/or optical switches, is discussed and optimised solutions introducing low penalties proposed.
Abstract: WDM optical communication systems are evolving from simple point-to-point links to complex network architectures. In wavelength routed networks switching is performed through optical add/drop multiplexer (OADM) and optical cross-connect (OXC) nodes. These nodes provide provisioning capabilities as well as protection and restoration at the optical layer. Routing and management of the traffic demands are applied through the generalised multiprotocol label switching (GMPLS) a control plane offering intelligence at the optical layer. A central subject of debate has been the comparison of optical and electrical switching technologies, however transparent solutions offer attractive features associated with reduced unnecessary optoelectronic conversions supporting transparent networks with reduced capital and operational cost. A number of different OADM and OXC architectures based on various technologies have been proposed to date. A detailed discussion on the different architecture and technology choices supporting a variety of features are given and specific design and implementation examples are analysed. The impact of impairments introduced by transparent elements present in the network, such as OADM and/or optical switches, is discussed and optimised solutions introducing low penalties proposed. In addition, the use of novel modulation formats improving the concatenation performance of such elements is covered.

TL;DR: This article presents a network framework for delivering optical services, and opens exciting opportunities for delivering new customized optical services directly to end-users, allowing carriers to fully exploit the economics of optical transport.
Abstract: Optical networks are growing at unprecedented rates to accommodate the explosion in data traffic brought on by new Internet and enterprise applications. Coupled with this growth has been the introduction of client devices (e.g., routers, storage devices, and content servers) at the network edge operating at optical line rates. These two trends are changing the fundamental way in which optical transport networks are being architectured, deployed, and managed. Emerging intelligent optical networks address the traffic scaling challenge. Additionally, when combined with modern service management technologies, these networks open exciting opportunities for delivering new customized optical services directly to end-users, allowing carriers to fully exploit the economics of optical transport. This article presents a network framework for delivering optical services.
