Parameter
Type
Description
PacketResendTimeout
Integer
The elapsed time (in ms) before the first resend
request for a missing packet is sent to the
camera. The default value is 0 ms, meaning the
request for a missing packet will be sent instantly.
This parameter applies only once to each
missing packet after the packet was detected as
missing.
PacketResendResponseTimeout
Integer
Represents how long (ms) the Packet Resend
Mechanism will wait for response after sending a
resend request, until another resend request is
sent.
MaxResendPacketRetry
Integer
Represents the maximum number of resend
requests sent for a missing packet.
MaxMissingPacketWaiting
Integer
Maximum time (in ms) the missing packet is
waited for. When this time expires, there will be
no more resend requests sent to camera even if
the driver did not send all resend request
specified with MaxResendPacketRetry and the
packet will be considered as lost.
MaxNextPacketWaiting
Integer
Maximum time (ms) that the resend mechanism
will wait for the next packet. If this time expires
and there are still retries left, the resend request
is sent again.
MaxMissingPacketsCount
Integer
Maximum number of missing packets in one
frame. If the frame has more missing packets
then this value it will be dropped.
MaxNewImagesPending
Integer
Maximum amount of new images pending in the
buffer. Current image is dropped if this amount is
exceeded.
MaxNewPacketsPending
Integer
Maximum amount of incoming payload packets
pending in the buffer. Current frame is dropped if
this amount is exceeded.
MaxIncompletePackets
Integer
Maximum amount of missing payload packets
from a block of the image to be accepted.

Note
In healthy networks it is not necessary to recover more than a small number of packets
per hundreds of transmitted images. Should the amount of packet resends rise to
a unnatural height, check the correctness of the physical network setup (cabling,
switches) and the network optimization settings located in chapter
7.1.3 - Network
Interface Optimization
