QoS-driven multipath routing for on-demand video streaming in a Publish-Subscribe Internet

Aiming to improve the performance of on-demand video streaming services in an Information-Centric Network, we propose a mechanism for selecting multiple delivery paths, satisfying bandwidth, error rate and number-of-paths constraints. Our scheme is developed in the context of the Publish-Subscribe Internet architecture and is shown to outperform state-of-the-art multi-constrained multipath selection mechanisms by up to 7%, and single-path or single-constrained multipath selection schemes by up to 17%, in terms of feasible path discovery, while at the same time improving on bandwidth aggregation. Also, it is suitable for supporting resource-demanding high-definition scalable video streaming services, offering Quality-of-Experience gains.
