[IEEE 2018 IEEE International Conference on Computer and Communication Engineering Technology (CCET) - Beijing, China (2018.8.18-2018.8.20)] 2018 IEEE International Conference on Computer and Communication Engineering Technology (CCET) - Lightweight Security Signaling Mechanism in Optical Network for Smart Power Grid
摘要： The communication security issue brought by Smart Grid is of great importance and should not be ignored in backbone optical networks. With the aim to solve this problem, this paper firstly conducts deep analysis into the security challenge of optical network under smart power grid environment and proposes a so-called lightweight security signaling mechanism of multi-domain optical network for Energy Internet. The proposed scheme makes full advantage of current signaling protocol with some necessary extensions and security improvement. Thus, this lightweight security signaling protocol is designed to make sure the end-to-end trusted connection. Under the multi-domain communication services of smart power grid, evaluation simulation for the signaling interaction is conducted. Simulation results show that this proposed approach can greatly improve the security level of large-scale multi-domain optical network for smart power grid with better performance in term of connection success rate performance.

[Institution of Engineering and Technology International Conference on Signal Processing (ICSP 2016) - Vidisha, India (7-9 Nov. 2016)] International Conference on Signal Processing (ICSP 2016) - Wavelength indexing based end-to-end routing in multi-domain optical networks under scheduled lightpath demands
摘要： Today’s multi-domain optical network (MDON) suffer resource unavailability crisis due to the ever increasing multi-media application based scheduled traffic (ST). In optical networks, the ST demands are referred as scheduled lightpath demands (SLDs). Thus, there is the pressing need to allocate resources efficiently throughout the network. In line of this, we present a wavelength indexing based end-to-end routing (WIR) strategy in MDON under SLD. As per the strategy, the demands are first sorted in increasing order of their holding time. For routing and wavelength assignment (RWA), the wavelength selection gets priority over the route selection. Corresponding to each wavelength, the shortest route from among the available K predefined candidate routes is assigned. The simulation results demonstrate improvement in the blocking probability and resource utilization with respect to the conventional RWA techniques named as scheduling based RWA (S-RWA) and greedy-RWA (G-RWA). The proposed strategy also improves the acceptance of intra- and inter-domain demands in MDONs.
