CDNs and P2P trunks are the prevalent techniques used for live streaming, each having its own set of advantages and disadvantages. LiveSky inherits the break down of both worlds: the tone of voice control and reliability of a CDN and the integral scalability of a P2P body. We address some(prenominal) key challenges in the constitution design and implementation including (a) dynamic resource scaling duty tour guaranteeing stream bore, (b) providing low startup ladecade cy, (c) ease of integration with unfeigned CDN infrastructure, and (d) ensuring network-friendliness and upload fairness in the P2P operation. LiveSky has been commercially deployed and used for some(prenominal)(prenominal) large-scale live streaming events serving more than cristal million users in China. We evaluate the performance of LiveSky using breeding from these real-world deployments.

Our results indicate that such a hybrid CDNP2P system provides quality and user performance comparable to a CDN and e?ectively scales the system capacity when the user volume exceeds the CDN capacity.
