I searched Google and Stackoverflow for information, but there are not many results and none of them was of much help.
We will have to implement our own protocol on top of UDP and "manually" fragment and reconstruct the data, but we could avoid this if we could find a way to reduce the packet reconstruction timeout on Windows to 500ms or less. We cannot use IPv6 (which would offer bigger packet ids) because there is no support for the hardware device. We cannot calculate the UDP checksum on the hardware device because of it's limited capabilities. So the longer the system runs, the more packet ids will be compromised until no communication is possible at all.
#Udp timeout settings on rv325 software
But they said on most firewalls you have to expand the UDP session timeout to avoid having to constantly reconnect the software console. To top it, the remaining fragments of the new #4711 packet are stored and combined with the next #4711 (which will be received a few seconds later). There is a software receptionist console that required a UDP port to be opened to the hosters network. Now the PC receives new fragments for (a new) packet #4711 and uses it to complete the old, still unassembled packet and assembles a damaged packet. Within this timespan a new packet with the same packed id is sent by the hardware device because of an overflow of the 16-bit packet id. Sometimes a packet (call it packet #4711) is lost and the PC side tries to reconstruct it for a long time. The supported range is minimum of 60 seconds and a maximum of 86400 seconds (24 hours), although the default 3600 seconds (1 hour) is recommended. TCP session timeout is the length of time an idle connection will remain in the Security gateway Connections Table.

These packets are fragmented by the hardware device and reconstructed by the network stack on the PC. Select Settings, Firewall, Advanced Configuration (you will need the router password - usually written on a label on the side of the router). Increasing Session Timeout for TCP services. The transmitted image data consists of packets with a size ranging from 6528 to 19680 bytes. The connect() operation is also subject to the timeout setting, and in general it is recommended to call settimeout() before calling connect() or pass a timeout parameter to createconnection. The device has a GBit connection to a dedicated switch and the PC uses a dedicated NIC and a 10GBit connection to this switch.
I am currently developing an image aquisition application in Visual C++ that receives image data from an UDP hardware device with limited capabilities (i.e.
