Welcome to the fourth installment of the IEEE Communications Magazine Series on Network Softwarization and Management. We are very excited to introduce this issue and write this first editorial as a new team of Series Editors. We start by expressing our sincere gratitude and appreciation to the past Series Editors, professors Alex Galis, Kohei Shiomoto (lead Editor), and Mohamed Faten Zhani, who were the first group of Editors to be assigned the responsibility of this ComMag Series and brought it to the current high quality level. We are honored to take over the Series from such an outstanding group of experts and will do our best to uphold the quality standards of the series and the magazine.
