基于传统体系结构的CDN内容分发服务性能分析
Performance characterization of CDN cache server based on traditional architecture
摘要
Abstract
With the rapid development of mobile Internet and Internet of Things,more and more terminal devices are con-nected to network edge nodes,and the amount of data has shown explosive growth,among which streaming media data accounts for more than 80％.Network edge devices need to request data from the data center,resulting in a sharp increase in traffic pressure on the backbone network,which leads to an increase in data transmission delay,and the quality of user service cannot be effectively guaranteed.Content distribution networks(CDN)is an effec-tive means to relieve the pressure on backbone networks and improve the quality of service.CDN caches data fre-quently accessed by users within a certain region at edge nodes of the network closer to the users,thereby reducing the network bandwidth pressure,lowering the data transmission latency and improving the quality of service.How-ever,network data content distribution,especially streaming media processing,has very strict requirements on ar-chitecture performance and power consumption,and network data content distribution applications have different characteristics from traditional high-performance applications.Therefore,how to design energy-efficient CDN server architecture has become an urgent problem to be solved.Based on this,this paper tests the performance of CDN content distribution application on traditional server architecture,including application type,central processing unit(CPU)utilization,branch prediction failure rate,Cache failure rate,network bandwidth,delay and off-chip stor-age performance.Based on the test results,this paper analyzes the architecture requirements of CDN content distri-bution applications that are different from traditional high performance computing(HPC)applications.Based on the analysis results,this paper gives corresponding design suggestions and optimization directions for CDN content distri-bution application architecture.Our research results have certain reference significance and practical value for the de-sign of high-throughput and energy-efficient CDN server architecture in the future.关键词
