摘要：

In this paper, we introduce a framework for designing an energy efficient cloud service for content delivery applications over non-bypass IP/WDM core networks. We develop a Mixed Integer Linear Programming (MILP) model to optimize network related factors including the location of the cloud in the network and whether it should be centralized or distributed, and cloud capability factors including the number of servers, switches, routers and amount of storage required at each cloud location. Our results indicate that distributing the cloud into many mini clouds in the network based on content popularity yields 40% total saving in power consumption compared to power un-aware centralized content delivery.
