Energy-Efficient Provisioning for Service Function Chains to Support Delay-Sensitive Applications in Network Function Virtualization
TL;DR: The simulation results show that EAR-ADS not only minimizes the cost of energy and resources but also achieves an excellent success rate and stability, and is efficient compared with an improved Markov algorithm (SAMA), reducing the average deployment time by more than a factor of 40.
