Abstract:
Network infrastructures such as Content Distribution Networks (CDNs) often need to prefetch bandwidth-intensive content for consumers of a plethora of applications, including elearning, healthcare, ecommerce, gaming, social activities, smart cities and environment management. With Internet traffic generated every day by online multimedia streaming providers reaching huge numbers, and the traffic growth being intensified by the circulation of media content over the well established Online Social Networks (OSNs), the performance of existent solutions can be improved in terms of latency the consumers of content experience, as well as bandwidth the media providers need. Our thesis is that information extracted from OSNs can be harnessed via an OSN-awareness mechanism that will mitigate the considerable weight placed on bandwidth and will facilitate proactive content caching decisions for the CDN infrastructure. This claim is supported by three case studies, which apply social information in situations where traditional bandwidth-intensive content scaling is infeasible, as replication demanded by traditional CDNs for the voluminous long-tail user-generated content becomes resource-intensive. Our approach is based on experimentation with empirical traces to identify relevant social properties and is followed by incorporation of the latter into current Content Delivery infrastructures.
