Hybrid Networking Techniques for Low-Latency Media-Rich Applications

With the ever increasing growth of media-rich applications from traditional video to virtual meeting/classrooms to tactile internet, the future networking paradigm will go away form a networking concept based on single-technology, single-flow, single-route model of information transfer, pushing the issues of usage prediction, integrated resource utilization and parallelism to all layers of protocol stack. Recent successful approaches, such as multi-homing, overlay networking, and distributed storage, deviate from this paradigm by using intelligent control to take advantage of redundancy and path diversity that already exist in the modern networks to provide a better experience to end-users.

Rather than treating the heterogeneous nature of the network and diversity of access technologies as an afterthought, this proposal considers an integrated approach that  systematically takes advantage of various hybrid networking techniques to improve upon the network experience in general, and in particular upon latency in media-rich applications.  These techniques include content caching, multicasting, multi-homing, multi-user coding, as well as braiding satellite+wifi+cellular technologies.
