“…Note that another type of FEC is used in optical transmission at very high speeds in connection with advanced modulation schemes [14]. Moreover, the use of NC has been proposed at the optical layer for dedicated protection [15]. In this paper, we utilize FEC at the network layer operating on data packets, and NC inside optical packet switches.…”

Abstract-Bufferless network operation is favorable in many application domains such as industrial networks, on-chip networks and optical packet switching (OPS). The main challenge with zero buffers is the avoidance or handling of contention; indeed, many domain-specific contention resolution techniques have been proposed in the literature. In this paper, we propose a generic combined forward error correction (FEC) and network coding (NC) scheme, which mitigates the negative impact of contentions at the network layer. Specifically, we present a case study for OPS utilizing FEC at the ingress node and NC at an intermediary optical packet switch to reduce packet loss due to contention. Our analysis shows that if used in a smart way, our mechanism can reduce decoding error and packet loss with multiple orders of magnitude while adhering to buffering limitations and meeting delay requirements. We believe that such a combined coding scheme has the potential to be utilized both in OPS (data center and core networks) and other networks where (near-)zero buffers are required.

“…Matsuda and Takine [95] proposed Reed Solomon/network joint coding, where G is set to be a generator matrix of ReedSolomon erasure correcting codes. Network erasure correcting codes are applied to various network environments of computer networks, e.g., protection in optical networks (Kamal [61], Manley et al [91]), and wireless sensor and wireless mesh networks (Al-Kofahi and Kamal [4]). …”

SUMMARYThis survey summarizes the state-of-the-art research on network coding, mainly focusing on its applications to computer networking. Network coding generalizes traditional store-and-forward routing techniques by allowing intermediate nodes in networks to encode several received packets into a single coded packet before forwarding. Network coding was proposed in 2000, and since then, it has been studied extensively in the field of computer networking. In this survey, we first summarize linear network coding and provide a taxonomy of network coding research, i.e., the network coding design problem and network coding applications. Moreover, the latter is subdivided into throughput/capacity enhancement, robustness enhancement, network tomography, and security. We then discuss the fundamental characteristics of network coding and diverse applications of network coding in details, following the above taxonomy.

“…NC allows intermediate network nodes to perform arbitrary mathematical operations to combine the data received from different links, thus offering numerous advantages over the traditional routing schemes [8]. This has been extensively studied in the context of optical multicast networks [9,10]. To mitigate the strong turbulence-induced fading, a cooperative relaying aided FSO transmission network based on NC and using an iterative multiple source detection scheme in conjunction with a chip-level soft network decoding at the relay and the destination node was proposed in [11].…”

Physical layer network coding (PNC) improves the throughput in wireless networks by enabling two nodes to exchange information using a minimum number of time slots. The PNC technique is proposed for two-way relay channel free space optical (TWR-FSO) communications with the aim of maximizing the utilization of network resources. The multipair TWR-FSO is considered in this paper, where a single antenna on each pair seeks to communicate via a common receiver aperture at the relay. Therefore, chip-interleaving is adopted as a technique to separate the different transmitted signals at the relay node to perform PNC mapping. Accordingly, this scheme relies on the iterative multiuser technique for detection of users at the receiver. The bit error rate (BER) performance of the proposed system is examined under the combined influences of atmospheric loss, turbulence-induced channel fading and the pointing errors (PEs). By adopting the joint PNC mapping with interleaving and multiuser detection techniques, the BER results show that the proposed scheme can achieve a significant performance improvement against the degrading effects of turbulences and PEs. It is also demonstrated that a larger number of simultaneous users can be supported with this new scheme in establishing a communication link between multiple pairs of nodes in two time slots, thereby improving the channel capacity.
