PROJECT: Interplay and Interactions of Socio-Technical Networks: A Case Study using Large-Scale Content Delivery over the Internet. A significant portion of today’s digital multimedia content is serviced by large content providers such as YouTube, Yahoo, Google, and the like. These large content providers often employ several huge data centers as well as a large number of geographically dispersed cache/proxy servers to meet and serve growing user demands. In this project, we propose to explore and study the interplay and interactions of socio-technical networks through network traffic. Understanding the interplay of socio-technical networks will not only help improve the operations and management of today’s Internet and emerging services such as cloud and mobile computing, but will also provide guidance to the design of future network architectures.
