Port address overloading based packet forwarding verification in SDN by Ping WU, Chaowen CHANG, Yingying MA

“…Aiming at the problem that the existing forwarding verification mechanisms in software-defined networking (SDN) incur significant communication overhead caused by embedding additional packet fields, a packet forwarding verification mechanism based on port address overloading was proposed, which key idea was the ingress switch implemented port address overloading by reconstructing port and address of packet, downstream switches executed packet probabilistic verification based on overloading port address, and the controller acquired valid and invalid packet statistics of node verification in the path and localized anomaly.Anomaly detection threshold of malicious injecting and dropping packets was presented by theoretical analysis.Finally, the proposed scheme was implemented and evaluated.Experiments demonstrate the proposed scheme achieves efficient forwarding and effective anomaly localization with less than 10% of additional forwarding delays and less than 8% of throughput degradation.…”

Simulation of transmission characteristics of oceanic wireless optical communication systems based on orbital angular momentum multiplexing with space-time coding by Xiaoli YIN, Tong ZHENG, Zhiwen SUN, Zhaoyuan ZHANG

“…In order to mitigate the crosstalk caused by oceanic turbulence in the underwater wireless orbital angular momentum multiplexing optical communication system, the application of space-time coding technology in the system was studied.Based on Rytov approximation, the covariance method and interpolation method were used to simulate correlated random phase screens and then the influence of time-varying oceanic turbulence channel on orbital angular momentum signal was studied.The transmission characteristics of orbital angular momentum multiplexing optical communication system with space-time coding was analyzed by simulation.The phase structure function of the time-varying phase screens and the detection probability distribution of the beam carrying the orbital angular momentum through the time-varying simulation channel were in line with theoretical expectations.The simulation results show that the space-time coding technology can effectively mitigate the influence of ocean turbulence on the system bit error rate.…”
