== Acceptance ==

As of 2018 RDMA had achieved broader acceptance as a result of implementation enhancements that enable good performance over ordinary networking infrastructure <ref>RoCE Rocks over Lossy Network: https://dl.acm.org/citation.cfm?id=3098588&dl=ACM&coll=DL</ref>. For example [[RDMA over Converged Ethernet|RoCE]] (RDMA over Converged EthernetRoCE) now is able to run over either lossy or lossless infrastructure. In addition [[iWARP|Internet Wide Area RDMA Protocol]] (iWARP) enables an [[Ethernet]] RDMA implementation at the physical layer using [[Transmission Control Protocol|TCP]]/[[Internet Protocol|IP]] as the transport, combining the performance and latency advantages of RDMA with a low-cost, standards-based solution.<ref>{{cite web|url=https://www.intel.com/content/dam/support/us/en/documents/network/sb/understanding_iwarp_final.pdf|title=Understanding iWARP|publisher=Intel Corporation|accessdate=16 May 2018}}</ref> The RDMA Consortium and the DAT Collaborative<ref>{{cite web|url=http://www.datcollaborative.org/|title=DAT Collaborative website|accessdate=14 October 2014|deadurl=yes|archiveurl=https://web.archive.org/web/20150117180600/http://www.datcollaborative.org/|archivedate=17 January 2015|df=}}</ref> have played key roles in the development of RDMA protocols and [[Application programming interface|APIs]] for consideration by standards groups such as the [[Internet Engineering Task Force]] and the Interconnect Software Consortium.<ref>[http://www.opengroup.org/icsc/ The Interconnect Software Consortium website] {{webarchive|url=https://web.archive.org/web/20050830201232/http://www.opengroup.org/icsc/ |date=2005-08-30 }}</ref>
