"Joint Software-Defined Application-Network Control Plane for Next Generation Real-Time Applications"
Current real-time applications such as telepresence systems require a verystrong
real-time interactivity. Requirements are even more stringent in multi-stream and
multi-site tele immersive applications due to strong dependencies across geographically
distributed streams. In this talk, I will argue for a joint software-defined application-
Network control plane to assist the next generation real-time applications such as
Telepresence and teleimmersion. Furthermore, I will discuss OpenSession, the
new 'Northbound' application-network control plane for multi-stream and
multi-site real-time applications, which represents the interaction between the application-level
session controller and Software-Defined Network (SDN) controller. OpenSession aims
to improve end-to-end latency, bandwidth utilization and scalability by decoupling
application data transport and control functionality, and partially offload the data
transport functionalities to network layer switches. The offloading of application
transport and control functions to network switches during their session run-time
happens via OpenSession by leveraging the SDN (e.g., OpenFlow) assistance. The
experiments with the OpenSession application-network control plane are very encouraging,
since OpenSession improves greatly the performance, interactivity and resources usage of our
real-time applications such as the 3D Teleimmersion.
