Abstract:
In the system of IPv6 video grid with guarantees of service quality, video data packets are transported by TCP protocol. According to the feature of TCP protocol, this paper utilizes passive measurement based on client method to realize the measurement of the network performance parameter of user’s video stream, such as delay, bandwidth, jitter, and proposes the concept and computation method of late rate.
