Anti-packet loss introduction time delay statistical method, anti-packet loss evaluation method and device

The embodiment of the invention discloses an anti-packet loss introduction time delay statistical method, an anti-packet loss evaluation method and device. The anti-packet loss introduction time delay statistical method comprises the following steps: when a data packet is received, obtaining the receiving time of receiving the data packet; when it is determined that the data packet is lost, recovering the lost data packet and recording the recovery time of the lost data packet; determining the receiving time of the lost data packets according to the receiving time of the plurality of received data packets; and calculating the time delay introduced by recovering the lost data packet according to the recovery time and the time to be received as the introduced time delay. On one hand, the introduction time delay for recovering the lost data packet is calculated through the recovery time and the receiving time of the lost data packet, the method is suitable for various lost packet recovery algorithms, and the uni
