A Multi-Domain Virtual Network Embedding Algorithm with Delay Predictioncations, how to improve the delay performance of the system has become a hot topic in academic circles. Based on extensive research, we proposed a multi-domain VNE algorithm based on delay prediction (DP-VNE). Firstly, the candidate physical nodes are selected by estimating the delay of virtual requ

Multi-Objective Enhanced Particle Swarm Optimization in Virtual Network Embedding problem. Prior studies on this problem only consider one objective, e.g., maximizing the revenues by mapping more virtual networks or minimizing the energy cost. In this chapter, we addressed the VNE problem with these two objectives. We leverage niche PSO technique to design a meta-heuristic algor

Incorporating Energy and Load Balance into Virtual Network Embedding Processhms focus primarily on the revenue of SPs and the acceptance ratio of VNRs, regardless of the energy consumption for substrate nodes and substrate links. To deal with this issue, some of researchers proposed energy-aware VNE algorithm to do a tradeoff between the revenue and energy consumption. Howe

In addition, it is difficult to deploy new network protocols on the existing Internet infrastructure. Therefore, the traditional Internet architecture gradually presents a rigid phenomenon.
