On the use of Reliable Multicast for Content Distribution

Content Distribution Networks (CDNs) are used to deliver content inexpensively in terms of network bandwidth and computational resources. The typical CDN architecture consists of an origin server and at least one level of content replication or caching servers. When content is replicated, CDN operation breaks up into two different stages: cache server synchronization and content delivery to the client. Our goal is to optimize the server synchronization process in terms of network bandwidth and computational resources. The protocol is based on multicast for the control and signaling, and on reliable multicast for the transmission of data.
