Abstract: In a system, a load balancer transmits, to a selected content origin node, a first content request based on a first request for first requested content received from a client node, the selected content origin node transmits, to the load balancer, a first response to the first content request, wherein the selected content origin node has the first requested content, and the load balancer transmits, to the client node, a first redirect message identifying the selected content origin node as having the first requested content without transmitting the first requested content to the client node. In some implementations, the selected content origin node transmits the first redirect message as the first response. In other implementations, the first response from the selected content origin node contains the first requested content, and the load balancer converts the first response into the first redirect message.

Abstract: Methods and systems for analyzing video quality of programming by content type. A method for analyzing video quality includes receiving, at a service provider system, video containing a source event. The system can sample the video at a least processed sampling point in the service provider system. An event feature set characterizing the source event is determined using the sampled video. The event feature set includes unique features that are same and unique features that are substantially same in videos including future occurrences of the source event. The system assesses the quality of one or more sampled videos taken at other delivery path points in the service provider system. The quality assessed using a source event no reference quality evaluator trained using at least the event feature set. The system outputs a quality metric for each of the one or more sampled videos taken at the other delivery path points.
