Milestones[ edit ] This signals a transport protocol like TCP to reduce its transmission rate to alleviate the congestion. Various error conditions may occur, such as data corruptionpacket loss and duplication. This suggests continually estimating the mean delay and its standard deviation and setting the playout delay so that only packets delayed more than several standard deviations above the mean will arrive too late to be useful.
