Abstract: A method and system of generating performance metrics for network traffic being transferred in and out of an intranet. Network traffic is non-intrusively measured from a server to client perspective within periodic measurement time intervals. The network traffic is analyzed based on each connection made from a server to a client and the measurement time interval. Using the network traffic analyzed, performance metrics are generated. Accumulated performance metrics are also generated when a connection extends beyond a measurement time interval.

Abstract: In general, a proxy-assisted staggered two-flow video streaming technique is described that provides controlled service assurance for individual videos delivered across a wide-area best-effort network. A server partitions an encoded video into an “essential” part and an “enhanced” part. The essential part includes video frames that have been encoded independently from the other frames of the video. The enhanced part includes video frames that have been encoded in a dependent fashion based on the other frames. A proxy server coupled to the server via a network, wherein the server delivers the essential part of the encoded video to the proxy server using a reliable network protocol, and the second part of the encoded video using an unreliable network protocol. The proxy server merges the essential part and the enhanced part to form a merged video stream, and delivers the merged video stream to a client device.
