Export of RoCEv2 Base Transport Header (BTH) Information Using IP Flow Information Export (IPFIX)

This document defines a new set of IP Flow Information Export (IPFIX) Information Elements (IEs) for exporting Base Transport Header (BTH) information for RDMA over Converged Ethernet version 2 (RoCEv2) traffic. These extensions enable network monitoring systems to collect and analyze the characteristics of RDMA traffic widely used in high-performance computing, storage, and artificial intelligence applications.
