It defines the UBoE packet encapsulation based on IPv4/IPv6 and UDP over Ethernet, including the invariant CRC (ICRC) integrity protection for end-to-end packet verification. This document further specifies the cross-domain packet conversion and header adaptation behaviors at UB2E switches, including bidirectional mapping rules for UB-specific network layer and IP network layer.}, }
