Abstract: A system includes a data processing unit (DPU) and DPU resource management circuits. A DPU resource management circuit establishes an interface associated with managing resources of the DPU, where establishing the interface is based on another DPU resource management circuit of the system accessing the DPU. The DPU resource management circuit monitors usage of the resources of the DPU based on auditing data provided by the second DPU resource management circuit. In some cases, the DPU resource management circuit may allocate resources of the DPU to an application. The DPU resource management circuit generates a catalog data structure of the resources of the DPU. The catalog data structure includes entries corresponding to resources of the DPU and functions provided by the resources.

Abstract: Communication apparatus includes a plurality of ports, including at least a first port configured to transmit and receive first data packets over a network in accordance with a network-layer protocol to and from a network management station, and a second port configured to be connected to a neighboring unmanaged device so as to transmit and receive second data packets to and from the unmanaged device in accordance with a link-layer protocol. A processor is configured to receive telemetry data from the unmanaged device via the second port in accordance with the link-layer protocol, to aggregate the received telemetry data in a memory, and to report the aggregated telemetry data to the network management station via the first port in accordance with the network-layer protocol.
