It first introduces the key issues and design choices of representative real-world CDNs, and discusses the energy saving techniques for data centers and CDNs. Then, based on a measurement study on a large video streaming CDN, it reveals an inherent conflict between improving a video streaming CDN?s energy efficiency for energy saving, and maintaining the CDN?s ISP-friendly server selection policy. Further, it discusses a cost-aware capacity provisioning algorithm that not only allows the service capacity of a CDN?s server clusters in numerous ISPs to be dynamically planned, but also means that the overall operating cost, including both the energy consumptions and the cross-ISP traffics, can be further optimized. In addition it uses the workload derived from real-world measurement and also implements real values of the actual power and bandwidth prices to evaluate the capacity provisioning algorithm, showing that it can significantly reduce the overall operating cost of a video streaming CDN, and effectively avoid frequent server switches. Lastly, the book outlines a number of potential research directions regarding cost-aware content delivery. The measurement, analysis, and optimization methodologies and results presented in this book are of particular interest to researchers in the Internet and networking area. 410 0$aSpringerBriefs in Computer Science,$x2191-5768 606 $aComputers 606 $aComputer communication systems 606 $aElectrical engineering 606 $aComputer system failures 606 $aInformation Systems and Communication Service$3https://scigraph.springernature.com/ontologies/product-market-codes/I18008 606 $aComputer Communication Networks$3https://scigraph.springernature.com/ontologies/product-market-codes/I13022 606 $aCommunications Engineering, Networks$3https://scigraph.springernature.com/ontologies/product-market-codes/T24035 606 $aSystem Performance and Evaluation$3https://scigraph.springernature.com/ontologies/product-market-codes/I13049 615 0$aComputers. 615 0$aComputer communication systems. 615 0$aElectrical engineering. 615 0$aComputer system failures. 615 14$aInformation Systems and Communication Service. 615 24$aComputer Communication Networks. 615 24$aCommunications Engineering, Networks. 615 24$aSystem Performance and Evaluation. 676 $a004.6 700 $aTian$b Ye$4aut$4http://id.loc.gov/vocabulary/relators/aut$0897533 702 $aZhao$b Min$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aZhang$b Xinming$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910254847403321 996 $aInternet Video Data Streaming$92538892 997 $aUNINA
