Abstract
A system incorporates notification aspects of a presence system with content distribution capabilities of a content delivery network to both notify subscribers of the presence of content from a host and provide relatively fast and efficient delivery of the content to the user. A content host provides content, such as streaming audio or video media, to a content delivery network. The content host also provides notification of the availability of the content to a central site or presence server. A subscriber to the content host receives, from the presence server, notification as to the availability of content by the content host. The subscriber also receives notification as to the location of the content in the content delivery network. Based upon the notification, the subscriber retrieves the content from the content delivery network.
