DOCA (Data Center Infrastructure on a Chip Architecture)
DOCA (Data Center Infrastructure on a Chip Architecture) is NVIDIA’s software framework for building and operating services on BlueField DPUs. Its objective is to standardize how operators and ISVs develop infrastructure applications—OVS offload, firewall/VNF, storage targets, RDMA/RoCE control, TLS inspection, telemetry agents—on Arm cores and hardware accelerators embedded in the NIC, using a consistent set of libraries instead of ad hoc kernel modules on the host. DOCA spans drivers, userspace APIs, reference pipelines, and marketplace-packaged applications; it is the DPU counterpart to CUDA on GPUs, oriented toward I/O and packet processing rather than tensor math.
