Energy Conservation Modeling and Online Optimization for Multimedia Server Cluster Systems
摘要
Abstract
An energy conservation optimal control approach is proposed for multimedia server cluster systems based on Markov switching state space control model. First the stochastic control model is introduced for multimedia server cluster systems. Under this model, the energy conservation control problem is formulated as a constrained optimization problem. Based on Lagrange multipliers method and performance potential theory, an online policy iterative algorithm is proposed. The algorithm solves the optimal control policy on-line by sample path and the solving procedure does not need any accurate system parameter information. Simulation experiments demonstrate the effectiveness of the proposed approach.关键词
