 RoCEv2 on the other hand utilizes UDP which has a far smaller overhead and better performance but does not provide inherent reliability, and therefore reliability must be implemented alongside RoCEv2.One solution is to use converged Ethernet switches to make the local area network reliable.This require converged Ethernet support on all the switches in the local area network and prevents RoCEv2 packets from traveling through a wide area network such as the internet which is not reliable.
