We apply the proposed architecture to streaming of scalable (layered) videos, where the base layer routes are dynamically optimized to fulfill a required QoS level, while enhancement layers follow traditional shortest path. We show that the proposed solution approaches the expensive non-scalable globally optimal solution (single controller for the whole network) in terms of received video quality under various congestion scenarios.Electrical electronics engineeringConference proceedinghttps://www.scopus.com/inward/record.uri?eid=2-s2.0-84875822149anddoi=10.1109%2fICIP.2012.6467340andpartnerID=40andmd5=4b507145110859c0373937e1cd40925e319334902072N/A8364
