the challenging demands for the next generation of the Internet of things have led to a massive increase in edge computing and network virtualization technologies. One significant technology is Multi-access Edge computing (MEC), a central piece of 5G telecommunication systems. MEC provides a cloud computing platform at the edge of the radio access network and is particularly essential to satisfy the challenging low-latency demands of future applications. Our previous publications argue that edge computing should be transparent to clients. We introduced an efficient solution to implement such a transparent approach, leveraging Software-Defined Networking (SDN) and virtual IP+port addresses for registered edge services. Building on our already efficient approach, in this work, we propose significant improvements to scale our transparent solution to large-scale real-world access networks. First, by improving the modularity of our SDN controller design, we enable various options to distribute boththe SDN controller's load and the switches' flows. Second, we introduce the Unique Mask, a solution superior to the Unique Prefix presented in our previous work that considerably reduces the number of required flows in the switches. Our evaluations show that both algorithms perform very well, withthe Unique Mask capable of reducing the number of flows by up to 98 %.

A novel backstepping global integral terminal sliding mode controller (BGITSMC) has been proposed in this paper for three - phase (3 - phi) grid - integrated solar photovoltaic (PV) systems by taking external disturbances (EDs) into consideration. the proposed controller ensures the dynamic stability of 3 - phi grid - integrated PV systems by controlling the voltage source converter (VSC). the control Lyapunov function (CLF) has been used to demonstrate the dynamic stability of the system withthe suggested control law. the robustness of the proposed controller has been examined through numerical simulations under various operating situations. Finally, by comparing the effectiveness of the suggested BGITSMC withthe existing sliding mode control (SMC) scheme revealed how much preferable it is at delivering active power into the grid and lowering total harmonic distortion (thD) in the grid current.
grid-forming converter can actively provide fast power support for the power system, and play a pivotal role in the new power system mainly based on new energy converters. Due to the weak overcurrent capability of the...
