IB has roce (RDMA Over Converged Ethernet, better thought of as IB over Ethernet) under it's standization umbrella and every major commodity NIC vendor (mellanox, broadcom, intel) now implements roce. We also have the roce support in the switch from all major switch vendors. IB as a link layer "failed" with most implementors leaving the ecosystem broadly because Ethernet link layer always wins in networking - this is more of an economic outcome than a standardization outcome in my mind. Due to roce, IB as a transport and software protocol has a solid multi-vendor ecosystem. Jason
