DiffServ Driver for cRIO
DiffServ - Differentiated Services
Differentiated services or DiffServ is a method of prioritizing UDP and TCP/IP packets on Ethernet networks to avoid network congestions. It uses a field in the IP-header which is read by the routers and then the routers handles the packet appropriately. Some industrial networks utilize this functionality. There are multiple approaches how to implement DiffServ in an application and they differ in most operating systems.
DiffServ is not natively supported in LabVIEW.
This MI-DiffServ Toolkit is provided with license for each cRIO it will be applied on. (Serial number must be provided to generate license file)
The toolkit will enable you to set the DiffServ level you want on all TCPIP connections opened on the cRIO.
