Timeout Resend Mechanism Parameters

The timeout resend mechanism is illustrated in Figure 29 where the following assumptions are
made:



The frame includes 3000 packets.



Packet 1002 is missing within the stream of packets and has not been recovered.



Packets 2999 and 3000 are missing at the end of the stream of packets (end of the frame).



The Maximum Number Resend Requests parameter is set to 3.

(1)

Stream of packets. Gray indicates that the status was checked as the packet entered the
receive window. White indicates that the status has not yet been checked.

(2)

Receive window of the performance driver.

(3)

As packet 1003 enters the receive window, packet 1002 is detected as missing.

(4)

Interval defined by the Resend Timeout parameter.

(5)

The Resend Timeout interval expires and the first resend request for packet 1002 is sent to
the camera. The camera does not respond with a resend.

(6)

Interval defined by the Resend Response Timeout parameter.

(7)

The Resend Response Timeout interval expires and a second resend request for packet
1002 is sent to the camera. The camera does not respond with a resend.

(8)

Interval defined by the Resend Response Timeout parameter.

(9)

The Resend Response Timeout interval expires and a third resend request for packet 1002 is
sent to the camera. The camera still does not respond with a resend.

(10) Interval defined by the Resend Response Timeout parameter.

(11) Because the maximum number of resend requests has been sent and the last Resend

Response Timeout interval has expired, packet 1002 is now considered as lost.

(12) End of the frame.

(13) Missing packets at the end of the frame (2999 and 3000).

(14) Interval defined by the Packet Timeout parameter.
