TCP Sessions in Adobe HTTP Dynamic Streaming

Hello All,

I have one question on the Adobe HTTP Dynamic Streaming.

In Microsoft Smooth Streaming two separate TCP sessions are initiated by the client to the sevrer for downloading the fragments irrespective of the bitrate changes. (One each for video and audio).

In the case of Apple HTTP Live Streaming there is one TCP session is created by the client to the server for every single bitrate request. So if the bit rate changes then a new TCP session is created.

I would like to know how this is in the case of Adobe?

1.How many TCP sessions are created?

2. Does it change in case of the bite rate fluctiations?

Regards
