# What Is RoCEv2?

> RoCEv2 (RDMA over Converged Ethernet v2) is a protocol that implements RDMA on Ethernet. Its packets are encapsulated in UDP/IP, so they can be routed across layer-3 networks. RDMA moves data directly between the memory of two machines, bypassing the operating-system kernel, which keeps latency and CPU usage low.
