RoCE incorporates the + IBTA RDMA semantics to allow devices to perform direct memory + to memory transfers at the application level without involving + the host CPU. Both the transport processing and the memory + translation and placement are performed by hardware resulting + in lower latency, higher throughput, and better performance + compared to software based protocols.</p> + + <p>RoCEv2 is the most recent version of RoCE, adding some routing + capabilities as both IP and UDP headers are included in the + packet format. To complete the RoCEv2 solution, Support for + ECN (Explicit Congestion Notification, lossy fabric) and PFC + (Priority Flow Control, lossless fabric) protocols with rate + limiting options will be added in the first quarter of + 2018.</p> + + <p>This project also introduces the following updates:</p> + + <ul> + <li><tt>libibverbs</tt>, <tt>librdmacm</tt>, + <tt>libibumad</tt> and vendor-specific libraries + ported from the Linux rdma-core v15+</li> + + <li>InfiniBand diagnostic tools, + <tt>infiniband-diags</tt>, version 1.6.7</li> + + <li>InfiniBand subnet manager — OpenSM, version 3.3.20+</li> + + <li>LinuxKPI support</li> + </ul> + + <p>Important notes:</p> + + <ul> + <li>GPL-only (non dual-licensed) portions of the Linux code were either + excluded or written from scratch under a BSD license by + &a.hselasky;.</li> + + <li>The code has been tested by several RDMA vendors + that also support iWARP.</li> + </ul> + </body> + + <sponsor>Mellanox Technologies</sponsor> + + <help> + <task>Add ECN (Explicit Congestion Notification) and PFC + (Priority Flow Control) support.</task> + </help> + </project> </report>
