Secure dynamic flow policy for content delivery networks

Content Delivery Networks (CDNs) have evolved to overcome the inherent limitations of the Internet in terms of user perceived Quality of Service (QoS) when accessing Web content. A CDN replicates content from the origin server to cache servers (also called surrogates), scattered over the globe, in order to deliver content to end-users in a reliable and timely manner from nearby optimal surrogates. Like many other network systems and services, securing data is becoming a crucial need for CDNs. Deploying and broadcasting contents across the geographically distributed servers require reliably secured flow and access control policies. In this article, we have developed a security mechanism for CDN based on dynamic source routing protocol where flow control can be supported with dynamic flow scenario.
