Media streaming has gained popularity due to convenience of playing it at one’s own leisure. It demands for smooth playing of media. However,with the increasing trend of media streaming and number of online users, it is getting difficult for content providers of popular media contents to handle media playing requests for popular media files. The number of simultaneous requests for media contents may affect uniform delivery of media contents and can lead to lower engagement of end-users.Content Delivery Network (CDN) plays an important role in streaming popular media contents by satisfying end-users’ requests through surrogate servers. However, in order to enhance end-users experience, it is not sufficient to only reduce response time of media segments. It also requires to have lesser number of stalls during media streaming. This entails for redirecting requests to suitable surrogate servers as well as managingthetime duration between delivery of subsequent segments of a media file.The proposed methodnamed Stall Aware Media Streaming (SAMS) focuses on enhancing end-users experience by reducing wait time during media streaming.It keeps track of the possibility of stalls during media streaming and adjusts the media segments delivery rate to end-users accordingly. This results in meeting Quality of Service (QoS) requirement of end-users for media streaming in a better way by content providers.
