Nowadays, people commonly use streaming technology to enjoy audio or video broadcasted from the server. With this technology, they do not need to download the content first. But, they can directly enjoy the content through the streaming mechanism. Generally, this technology requires high bandwidth to maintain its Quality of Service (QoS) to stay at a good level. The problem can occur, such as packet loss because of limited bandwidth supported by the network provider. This condition can reduce the quality of the content delivered. One technology that can be used to improve the quality of content delivered by streaming service is CDN (Content Delivery Network). This study is going to improve the quality of live video streaming by using CDN. The global CDN infrastructure used is Cloudfront, supported by AWS (Amazon Web Services). The broadcaster is located in Bandung, Indonesia, and the client is placed in Tokyo, Japan. HTTP Live Streaming (HLS) format is performed for content streaming. It is proved CDN can increase the QoS of content delivered. The result presents live video streaming with CDN has better achievement than the other one without CDN. The broadcasting of live video streaming gives a throughput average of 4452.6 kbps and a packet loss ratio average of 0.08% by using CDN. Without using CDN, it presents the throughput average of 3990.4 kbps and the packet loss ratio average of 0.33%.
