Abstract—Streaming is a popular technology used by active users for enjoying audio or video. Broadly, this technology needs high bandwidth to carefully keep its Quality of Service (QoS) at a reasonable level. Without enough bandwidth, a problem arises, such as packet loss. This condition can decrease the quality of content delivery. To properly handle that problem, cache technology can be utilized. One type of these technologies is Content Delivery System (CDN). Naturally, the position of CDN has to be placed not far from the user area, so the access time can be faster than the access time when the CDN is not used. Another contributing factor, such as the right video format selecting can provide a good impact. There are two popular formats for live video streaming, such as HLS (HTTP Live Streaming) and RTMP (Real Time Messaging Protocol). This study is going to elaborate on the comparative between HLS and RTMP with CDN and also without it. The result shows live video streaming with CDN has better performance than without CDN.
