CDNs and P2P shorts are the everyday techniques use for live streaming, each having its avow set of advantages and disadvantages. LiveSky inherits the better of two worlds: the tone of voice go steady and reliability of a CDN and the intact scalability of a P2P system. We address some(prenominal) cardinal challenges in the system design and implementation including (a) dynamic vision scaling spell guaranteeing stream quality, (b) providing low startup ladecadecy, (c) repose of integration with actual CDN infrastructure, and (d) ensuring network-friendliness and upload fairness in the P2P operation. LiveSky has been commercially deployed and used for several big live streaming events percentage more than ten one million million million users in China. We evaluate the act of LiveSky using information from these real-world deployments.

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