Replica Placement Algorithms with Latency Constraints in Content Distribution Networks
نویسندگان
چکیده
Content distribution networks (CDNs) are a recent development to improve the performance of networked applications. The design of replica placement algorithms is one of the foremost problems in CDNs. Current replica placement methods do not guarantee a bound on the maximum latency to any client. In this paper, we propose several algorithms for replica placement with latency constraints. The algorithms are compared with respect to scalability and performance under a variety of conditions, including the case where clients’ request patterns are unknown.

متن کاملOn the Placement of Web Server Replicas
Recently there has been an increasing deployment of content distribution networks (CDNs) that offer hosting services to Web content providers. CDNs deploy a set of servers distributed throughout the Internet and replicate provider content across these servers for better performance and availability than centralized provider servers. Existing work on CDNs has primarily focused on techniques for ...
