He mentioned hardware-accelerated packet routing. RoCE is not a routing protocol -- it's a UDP packet using IB verbs to DMA directly to hardware on the PCIe bus

He mentioned hardware-accelerated packet routing. RoCE is not a routing protocol -- it's a UDP packet using IB verbs to DMA directly to hardware on the PCIe bus and bypass the processor. But yes, RoCE is a really interesting protocol and seems to have won the RoCE versus iWarp war.
