摘要：Content Delivery Networks (CDNs) have evolved to overcome the inherent limitations of the Internet. CDNs approach is based on the observation that serving web content from a single location can present serious problems for site scalability, reliability and performance. Hence, a system is devised to serve requests of end-user from nearby optimal surrogate server. CDN replicates content from the origin server to cache servers scattered over the globe. This seminar reports provides the broad coverage of CDNs in terms of layered architecture, basic interactions, technical issues involved, applications, advantages and disadvantages. It also provides the analysis of state-of-arts of existing CDNs and their comparative study on the basis of content distribution and management and request routing technique
