CDNs and P2P trunks are the day-after-day techniques used for live streaming, each having its own set of advantages and disadvantages. LiveSky inherits the intermit of both worlds: the tone of voice control and reliability of a CDN and the integral scalability of a P2P trunk. We address some(prenominal) key challenges in the organization design and implementation including (a) dynamic resource scaling enchantment guaranteeing stream role, (b) providin g low startup ladecadecy, (c) ease of integration with effective 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 hug drug million users in China. We evaluate the performance of LiveSky using discipline 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.
