Resilient peer-to-peer streaming of scalable video over hierarchical multicast trees with backup parent pools

► We propose a new cross-layer design for peer to peer video streaming. ► Resilient multicast trees are constructed with backup parent pools. ► Resilient capacity-aware tree formation algorithm suits scalable video streaming well. ► We propose backup parent selection strategy according to underlying topology. ► Simulations show that the proposed system provides seamless streaming.
