A jitter buffering system and a method of jitter buffering. The jitter buffering system may be embodied in a quality of service (QoS) management server, including: (1) a network interface controller (NIC) configured to receive one-way-delay statistics regarding a video stream transmitted to a client, and (2) a processer configured to employ the one-way-delay statistics to calculate and recognize jitter and subsequently generate a command for the client to enable jitter buffering.
