Abstract: A streaming server receives a first request to view the media item from the client device via a connection between the client device and the streaming server. An encrypted portion of the media item is provided to the client device. A cryptography key is sent to the client device for decrypting the encrypted portion of the media item by the client device to facilitate the playback of the decrypted portion of the media item. A verification is received to determine whether the client device is authorized to play the decrypted media item.

Abstract: Technology for characterizing internet application performance is described. An example method may involve, analyzing client requests from a plurality of internet service providers, the client requests comprising requests to access media items and being associated with internet service provider identities; identifying a set of the client requests that are associated with a first internet service provider; determining for at least one client request of the set: a request time, a payload data quantity, and an elapsed time; calculating a transfer rate comprising an application level throughput for the at least one client request, the transfer rate being based on the payload data quantity and the elapsed time; and calculating a performance measurement of the first and second internet service providers, the performance measurements being based on the transfer rate and on a portion of the set of client requests that have a transfer rate meeting a transfer threshold.
