摘要： The network densi?cation of small cells (SCs) is a promising way to cope with the explosive growth of future traf?c demands in 5G networks. However, the overall power consumption and the backhaul limitation of the network have become the key factors affecting the network performance and users’ quality-of-experience, which have great importance in 5G wireless networks. Due to the complexity of 5G networks and the variety of user behaviors, the combination of software-de?ned networks and content delivery strategy could be a more ef?cient way to manage such networks. In this paper, a cache-enabled wireless heterogeneous network with the control-plane (C-plane) and user-plane (U -plane) split is proposed, where the macro cell and SCs with different cache abilities are overlaid and cooperated together in the backhaul scenario. Using an evaluation tool composed of stochastic processes and classical power consumption model, key performance indicators, e.g., the coverage probability, throughput, and energy ef?ciency (EE), are derived as closed-form expressions or the functions of the signal-to-interference-plus-noise ratio threshold, path loss exponent, transmission power and density of macro and SCs, cache ability, ?le popularity, and backhaul capacity. Fundamental trade-offs are illustrated between EE and transmission power, EE and SC density, as well as the throughput and density of SCs. Numerical results show that the proposed cache-enabled software-de?ned networks have much higher throughput and improved EE than current LTE networks, which shows a promising solution for future cellular networks.

[IEEE 2018 20th International Conference on Transparent Optical Networks (ICTON) - Bucharest (2018.7.1-2018.7.5)] 2018 20th International Conference on Transparent Optical Networks (ICTON) - Monitoring Intent for Optical Channel Defragmentation in Software-Defined Elastic Optical Networks
摘要： As optical networks become more and more elastic to adapt to data traffic demands, knowing the health of the network is of key interest. We propose a monitoring intent framework to facilitate the development of control functions exploiting the monitored optical parameters. We then demonstrate an optical channel defragmentation control function deployed as an SDN application taking advantages of a centralized view of SDN controller to optimize the spectrum utilization.

[IEEE 2018 2nd IEEE Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC) - Xi'an (2018.5.25-2018.5.27)] 2018 2nd IEEE Advanced Information Management,Communicates,Electronic and Automation Control Conference (IMCEC) - Physical-Layer-Factor Constrained Multicast Scheme in Software Defined Optical Networks
摘要： As the scale of software defined optical networks (SDON) grows with ever increasing multicast services, the communication quality suffers seriously from physical-layer-factor (PLF). Aimed to solve this problem, a PLF constrained optical multicast mechanism is proposed for OpenFlow controlled optical networks. This proposed approach takes these PLF model including both of linear factors and non-linear ones into optical multicast controlled by OpenFlow. Thus, the proposed scheme is able to cover nearly all PLF of each optical link and to conduct optical multicast with better communication quality. Simulation results show that the proposed scheme is able to better performance of SDON optical multicast services.
