The Internet has been successfully deployed for several decades due to its high flexibility in running over different physical media and supporting different high-layer protocols and applications, including traditional file transfer, email, and client-server-based web applications, among others. The future Internet is expected to be more agile, scalable, secure, and reliable. Meanwhile, we have witnessed the unprecedented development and growth of new applications and services in recent years ranging from location-based services, social networking, cloud computing, and peer-to-peer (P2P)-based applications. Such rapidly emerging applications with different requirements and implications for the future Internet design pose a significant set of problems and challenges.
