RoCEv2和rdma标准文档

RoCEv2和rdma标准文档 This document is an annex to Volume 1 release 1.2.1 of the InfiniBand Architecture, herein referred to as the base specification. This annex is Optional Normative, meaning that implementation of the feature described by this annex is Optional, but if present, the implementation must comply with the compliance statements contained within this annex. This specification follows the spirit of the RoCE Annex (Annex A16 to the base specification) in defining a new InfiniBand protocol variant that uses an IP network layer (with an IP header instead of InfiniBand‘s GRH) thus allowing IP routing of its packets.
