Abstract:
1. A method of non-intrusive determination of a transmission quality of a first communication link between a transmitter device and a receiver device, said method being implemented by a transmission quality monitoring device, wherein said method comprises the following steps: reception, by said transmission quality monitoring device, from said transmitter device, of first data packets and storing of at least part of said first data packets as reference data packets; reception, by said transmission quality monitoring device, of retransmitted packets, said retransmitted packets being at least part of said first data packets that are transmitted from said transmitter device to said receiver device via said first communication link, received by said receiver device, and retransmitted by said receiver device to said transmission quality monitoring device via a second communication link, said second communication link being different from said first communication link of which transmission quality is to be determined; determination, by said transmission quality monitoring device, of said transmission quality of said first communication link between said transmitter device and said receiver device through comparison between said reference data packets and said retransmitted packets.
