ABSTRACT
In delay-sensitive real-time streaming applications, when a packet
is not delivered within an expected amount of time, an important
issue is to determine whether the missing packet is merely delayed
or is already lost. Historically, inherited from TCP jargon, the
duration after which the missing packet is assumed to be lost is
referred to as retransmission timeout (RTO). Regardless of doing
a retransmission or not, timely inference of late/lost packets is cru-
cial for real-time streaming applications, so that well-timed actions
can be taken by the server/client. In this paper, we introduce a
new client-driven RTO estimation algorithm that can be used in
conjunction with any error-control method for streaming real-time
audio/video. Our goal is to identify the lost packets as quickly as
possible, while keeping the chance of any misidentification, i.e.,
