Live Smooth Streaming, an IIS Media Services 3.0 extension, enables adaptive streaming of live events to Smooth Streaming clients, such as Microsoft Silverlight 3. Using HTTP to deliver live events takes advantage of the scale of existing HTTP networks and keeps content close to the end user and makes true HD (720p+) a realistic option for live Web broadcasts. The additional advantage of using HTTP-based delivery for live events is that the existing HTTP infrastructure also drastically increases live event availability. For the most popular live Web broadcasts, CDNs and content providers have to worry about how much capacity they can dedicate on their much more resource constrained streaming network. By using HTTP, they can take advantage of all the resources of their network and do not have to worry about maxing out network capacity and shutting out users from live events.
