In this book, based on the analysis of the principle of VNE algorithm, we provide a VNE scheme for users with differentiated QoS requirements. We summarize the common user requirements into four categories: security awareness, service awareness, energy awareness, and load balance, and then introduce the specific implementation methods of various differentiated QoS algorithms. This book provides a variety of VNE solutions, including VNE algorithm for a single physical domain, VNE algorithm across multiple physical domains, VNE algorithm based on heuristic method, and VNE algorithm based on machine learning method. Finally, we summarize the whole content. weiterlesen
