“…In order to address the looming capacity crunch, various solutions are considered by research and industrial community, including space division multiplexing [2,3], fiber nonlinearity compensation [4], flex-grid networks [5], etc. Although spatial multiplexing, in one form or the other, will enable uninterrupted capacity growth, it is still an immature technology, and a more practical solution is favored for near-and medium-term network deployments.…”

“…Flex-grid networks, or software defined networks have recently gained significant interest, in order to cater the ever-increasing dynamic bandwidth demands [5][6][7][8][9]. The core concept of flex-grid networks is borrowed from radio communications, where an agile control plane is able to switch the link to employ the most optimum modulation type, data-rate, spectral-grid, etc., based on a given demand.…”

Abstract:We report on the nonlinear transmission limits of various superchannel configurations in a flex-grid network upgrade scenario. In particular, we consider flexible data-rates ranging from 180Gb/s to 1.2Tb/s, employing either single-carrier, dual-carrier, or penta-carrier polarization multiplexed m-state quadrature amplitude modulation (PM-8QAM/PM-16QAM) -termed as super-channels, and establish transmission performance margins for each configuration, both with and without superchannel fiber nonlinearity compensation. Our results show that the benefit of intra super-channel nonlinearity mitigation (nonlinear compensation addressing full super-channel bandwidth) reduces with increasing subcarrier count within the super-channel, and that single-carrier super-channel achieves the maximum improvement from nonlinearity mitigation (up to ~4.5dB, in Q-factor), better than dual-carrier (up to ~3.5dB) and pentacarrier (up to ~2dB) configurations. Moreover, the maximum reach improvement, compared to linear compensation only, is found to be ~170%

“…Presently, there are a number of wired communication technologies and standards that can be used in electrical power communication networks, such as 100 Gbps optical fibers physical infrastructure, Synchronous Digital Hierarchy (SDH) technology, and Automatically Switched Optical Network (ASON) architecture [4]. But there is also another important challenge that is to provide a reliable and flexible last mile communication.…”

Internet of Things or wireless sensor networks (WSNs) can be utilized in monitoring electrical power consumption. For electrical power application, the main issue is how to effectively apply self-organized WSNs technology to handle the last mile communication and supply the reliable, real-time transmission. For example, great number of renewable generators' instantaneous voltage and power parameters should be reported in real time to dispatching center, which is the primary guarantee to keep the power system's stability. In this paper, integrating traffic engineering and distributed agent technologies, a novel distributed agents QoS routing algorithm is proposed to transmit electrical information flows with multi-QoS constraints. The algorithm can explore fast forward path with multiagents and guarantee transmitting quality with smooth allocating different traffic. We also present the mathematical analysis to prove the algorithm's validity. Finally, in the computer simulation, the average end-to-end delay, routing overhead, and links' bandwidth occupation ratio are computed to evaluate the algorithm performance. Coincident results show that the new algorithm can provide short end-to-end transmission with optimal utilized communication resource. A health infrastructure with load balance can effectively avoid the potential congestion and has robust capability to bear abrupt strong traffic flows.
