Minimize the Cost of Video Transmission Among Cloud Data Center and Edge Cloud CDN Nodes

With the development of cloud computing, more and more video service providers use services from cloud providers. A video service provider can construct a scalable video streaming platform with high availability by the cloud services. Typically, a video service provider uploads its video data to a cloud data center. Then, the cloud data center distributes the video data to its edge cloud CDN nodes. Usually, the cloud data center links with its edge cloud CDN nodes by high-capacity links, spanning different geographical regions. Video traffic across the cloud data center and the edge cloud CDN nodes of a cloud provider, brings on large operational cost to the cloud provider. How to reduce the video traffic cost is important for a cloud provider. Therefore, to reduce the video traffic cost, we propose a set of algorithms based on network maximum flow and minimum cut, called Netcut-way. The proposed Netcut-way, charged by the peak-bandwidth billing model, consists of three parts. The first is peak bandwidth calculation. The second is video segment segmentation. The third is video distribution route. Through extensive simulations, we demonstrate that Netcut-way can effectively reduce the operational cost of cloud providers in video traffic across data centers.
