application level session logs from a commercial streaming service.
over 185,000 sessions for RealMedia streaming objects, over a seven days period from Dec 13-19,2001 were analyzed.
A streaming session is initiated when a new request for a streaming object is received at a streaming node. The session terminates either when the client sends a termination request, or due to some error situation. At
termination, a single entry is created in the log summarizing a range of information for that session. The fields in each log entry include: requesting IP address, particulars of requested resource, whether the file is a Real or Windows Media object, transport protocol used for streaming (TCP or UDP), total data transmitted, total packets, session end-time, total session time, status/error codes, etc.
