The UDP packets or TCP packets transmitted by VVR that are of size greater than the network Maximum Transmission Unit (MTU) are broken up into IP packets of MTU size by the IP module of the operating system. There may be losses on the network because the packets are going through routers that do not support IP fragmentation and have a smaller MTU than your network device. In this case, make the MTU size the same as the MTU size of the router with the smallest MTU in the network.
