In essence, CloudSec is MACSec-in-UDP using Transport Mode, similar to ESP-in-UDP in Transport Mode as described in RFC3948. In addition to the specifics of transporting MACSec encrypted data over IP networks, CloudSec also carries a UDP header for entropy as well as an encrypted payload for Network Virtualization use-cases.
