英文摘要 | As the fast increasing of multi-domain networks, energy efficiency has been widely focused on and become a critical issue in service function chaining (SFC). In this paper, we propose an energy-aware method for multiple SFC-enabled domain networks. Firstly, based on hierarchical SFC (hSFC), we propose a hierarchical control architecture to support the orchestration that allows service chains across multiple domains. Secondly, this paper proposes an energy-aware service function chain placement (EA-SFCP) algorithm that minimizing the power consumption of each service chain. Thirdly, we also propose an energy-aware service function chain migration (EA-SFCM) algorithm to improve the overall energy efficiency of the network. Finally, we implemented the proposed algorithms and conducted comparison simulations with existing algorithm to evaluate their performance. The results show that can reduce power cost at least 33.3% over the candidate algorithm. |
