Abstract
The Content Delivery Networks (CDN) host the rich and bandwidth consuming content of an organization and process the requests of clients and deliver the content for them. With the extension of these networks and also distributive nature of the resources on them, it is necessary to ensure the desired quality of service for users of these networks. One of the important requirements of maintaining quality of access over the content delivery networks is to utilize an efficient data replication algorithm. This brief review, first explains the necessity of using data replication over the CDN networks and then discusses the challenges exist in this process. The paper then describes the popular replication methods in Content Delivery Networks. The heuristic method as an effective algorithm for data replication is also presented.
