ABSTRACT:
Server-side determination of quality of service received by a client. Content is transmitted from the server to the client according to a protocol. During transmission, the protocol requires the client to periodically send the server statistics concerning the transmitting, e.g., lost packets, latency, or the like. The server simulates the network connection between the client and server based at least in part on the received statistics. The simulating allows the server to recreate, server-side, the content received by the client. The server may then compare what was sent to the client, versus the recreated received content, to determine a quality of service received by the client.
