CDNs and P2P trunks are the cursory techniques used for live streaming, each having its own set of advantages and disadvantages. LiveSky inherits the discover of both worlds: the tone of voice control and reliability of a CDN and the integral scalability of a P2P establishment. We address some(prenominal) key challenges in the strategy design and implementation including (a) dynamic resource scaling number guaranteeing stream feature, (b) providing low startu p ladecadecy, (c) ease of integration with substantial 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 tenner million users in China. We evaluate the performance of LiveSky using nurture 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.
