transparent end-host-based service composition through network virtualization
Mobile devices have become a popular medium for delivering multimedia services to end users. A large variety of solutions have been proposed to flexibly compose such services and to provide quality-of-service guarantees for the resulting contents. However, low-level mobility artifacts resulting from network transitions (disconnected operation, reconfiguration, etc.) still prevent a seamless user experience of these technologies. This paper presents an architecture for supporting legacy applications with such solutions in mobile scenarios. Through network virtualization, it hides mobility artifacts and ensures connectivity at the network and transport level. Its adoption for multimedia applications poses unique challenges and advantages, which are discussed herein.
