“…This can be accomplished by converting the optical signal to an electronic symbol, performing the operations using normal electronic computations, and then converting the result back into an optical signal for retransmission. This constant optical-electical-optical conversion and stopping/buffering of the flow is undesirable, and so the use of all-optical XOR gates for coding operations has been explored [5], [6], [7]. Using only XOR gates, however, limits coding operations to simple addition whereas most networking coding applications also require at least some scalar multiplication in the computing of a linear combination.…”

“…Kamal et al proposed network-coding schemes for survivable optical networks [2], [3], [4] in which electronic network coding operations supported the optical protection schemes. Menendez and Gannet [5] proposed performing the coding operations for survivability at the optical layer using alloptical XOR logic gates, and Hisano et al [6] and An et al [7] recently demonstrated network coding functionality using all-optical XOR logic gates. We investigated optical switch and optical network coder architectures which would provide unrestricted digital network coding capabilities at the optical layer [8], and Liu et al applied an asynchronous network coding strategy at the optical layer [9].…”

Network coding, a networking paradigm in which different pieces of data are coded together at various points along a transmission, has been proposed for providing a number of benefits to networks including increased throughput, robustness, and security. For optical networks, the potential for using network coding to provide survivability is especially noteworthy as it may be possible to allow for the ultra-fast recovery time of dedicated protection schemes with the bandwidth efficiency of shared protection schemes. However, the need to perform computations at intermediate nodes along the optical route leads to the undesirable necessity of either electronically buffering and processing the data at intermediate nodes or outfitting the network with complex photonic circuits capable of performing the computations entirely within the optical domain. In this paper, we take the latter approach but attempt to mitigate the impact of the device complexity by proposing a low-complexity, all-optical network coder architecture. Our design provides easily scalable, powerful digital network coding capabilities at the optical layer, and we show that existing network coding algorithms can be adjusted to accommodate it.

Abstract-Parallel transmission, as defined in high-speed Ethernet standards, enables to use less expensive optoelectronics and offers backwards compatibility with legacy Optical Transport Network (OTN) infrastructure. However, optimal parallel transmission does not scale to large networks, as it requires computationally expensive multipath routing algorithms to minimize differential delay, and thus the required buffer size, optimize traffic splitting ratio, and ensure frame synchronization. In this paper, we propose a novel framework for high-speed Ethernet, which we refer to as network coded parallel transmission, capable of effective buffer management and frame synchronization without the need for complex multipath algorithms in the OTN layer. We show that using network coding can reduce the delay caused by packet reordering at the receiver, thus requiring a smaller overall buffer size, while improving the network throughput. We design the framework in full compliance with high-speed Ethernet standards specified in IEEE802.3ba and present solutions for network encoding, data structure of coded parallel transmission, buffer management and decoding at the receiver side. The proposed network coded parallel transmission framework is simple to implement and represents a potential major breakthrough in the system design of future high-speed Ethernet.

“…The results confirm that the proposed MSMR scheme can obtain the obvious diversity gain with considering the effects of scintillation, thermal noise, background noise, and multiuser interference, and the rapid convergence property has been demonstrated by Extrinsic Information Transfer (EXIT) chart. Compared with the MSMR scheme requiring multiple relay nodes [18], in this paper, one single relay node is sufficient for serving the multisource, saving the equipment cost.Currently, a new form of cooperative relay method, known as network coding, has attracted tremendous interest [12][13][14][15]. It can increase the system throughput and transmission robustness.Menendez and Gannet [12] proposed a photonic XOR network coding technique for efficient and fault-tolerant all-optical networks.…”

Network‐coded multiple‐source cooperation aided relaying for free‐space optical transmission

SUMMARY A network‐coded cooperative relaying aided free‐space optical (FSO) transmission scheme is designed. The resultant multiple‐source cooperation diversity is exploited by the relay to mitigate the strong turbulence‐induced fading experienced in FSO channels. At the destination, an iterative multiple source detection algorithm is proposed in conjunction with a chip‐level soft network decoding method. Our performance evaluation results using simulation analysis demonstrate that the proposed FSO multiple source detection is capable of approaching the single‐user‐bound for transmission over Gamma–Gamma turbulence channels. Also, the network‐coded cooperative FSO scheme can achieve a significant BER improvement in comparison with conventional noncooperation schemes. Copyright © 2012 John Wiley & Sons, Ltd.
