A cross entropy based approach to minimum propagation latency for controller placement in Software Defined Network

Jue Chen et al.

Summary: SDN plays a crucial role in data centers and wide-area networks, and a major challenge is to select appropriate controller locations and address latency issues between controllers and switches in a logically centralized architecture. A cross entropy-based approach is proposed to solve the Controller Placement Problem, which has been shown to achieve minimal propagation latency in various network scales and configurations with stable computation results.

Kalman Filter-Based Data-Driven Robust Model-Free Adaptive Predictive Control of a Complicated Industrial Process

Ping Zhou et al.

Summary: This article introduces a novel Kalman filter-based robust model-free adaptive predictive control (MFAPC) method for controlling molten iron quality in the blast furnace (BF) ironmaking process. The method extends the existing single-variable MFAPC method to multivariable systems using a compact-form dynamic linearization approach. A robust MFAPC is proposed to address data loss and measurement noise issues in quality detection, combining dynamic linearization with a Pseudo-Jacobian matrix for predicting missing data and using a Kalman filter to filter measurement noise.

Multi-Objective Control Plane Dimensioning in Hybrid SDN/Legacy Networks

Tamal Das et al.

Summary: Although SDN is gaining popularity in network operations, there is a lack of research on the placement of SDN controllers in hybrid SDN networks. This paper introduces and formulates a multi-objective control plane dimensioning problem, taking into account network resilience, flow-setup latency, and controller load balancing as objectives.

Resiliency-Aware Deployment of SDN in Smart Grid SCADA: A Formal Synthesis Model

A. H. M. Jakaria et al.

Summary: The study proposes a framework named SDNSynth, which can design a hybrid network consisting of both traditional devices and programmable SDN switches. The design aims to meet the resilience requirements of the SCADA network, including the best placement of SDN switches and certain requirements included in it. By simulating the suggested networks in a Mininet environment, the effectiveness of the deployment strategy over traditional networks during network congestions is demonstrated in terms of packet loss and recovery time.
