Abstract: A network interface device comprises a streaming data processing path comprising a first data processing engine and hubs. A first scheduler associated with a first hub controls an output of data by the first hub to the first data processing engine and a second scheduler associated with a second hub controls an output of data by the second hub. The first hub is arranged upstream of the first data processing engine on the data processing path and is configured to receive data from a first upstream data path entity and from a first data processing entity implemented in programmable circuitry via a data ingress interface of the first hub. The first data processing engine is configured to receive data from the first hub, process the received data and output the processed data to the second hub arranged downstream of first data processing engine.

Abstract: A network interface device has a data source, a data sink and an interconnect configured to receive data from the data source and to output data to the data sink. The interconnect has a memory having memory cells. Each memory cell has a width which matches a bus segment width. The memory is configured to receive a first write output with a width corresponding to the bus segment width. The write output comprises first data to be written to a first memory cell of the memory, the first data being from the data source.

Abstract: Roughly described, a network interface device receiving data packets from a computing device for transmission onto a network, the data packets having a certain characteristic, transmits the packet only if the sending queue has authority to send packets having that characteristic. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. Authorizations can be programmed into the NIC by a kernel routine upon establishment of the transmit queue, based on the privilege level of the process for which the queue is being established. In this way, a user process can use an untrusted user-level protocol stack to initiate data transmission onto the network, while the NIC protects the remainder of the system or network from certain kinds of compromise.

Abstract: A network interface device has an input configured to receive data from a network. The data is for one of a plurality of different applications. The applications may be supported by a host system. The network interface device is configured to determine which of a plurality of available different caches in a host the data is to be injected. The network interface device will then inject the determined cached with the received data.

Abstract: Embodiments herein describe creating tag bindings that can be used to assign tags to data corresponding to different tenants using a data processing unit (DPU) such as a SmartNIC, Artificial Intelligence Unit, Network Storage Unit, Database Acceleration Units, and the like. In one embodiment, the DPUs include tag gateways at the interface between a host and network element (e.g., a switch) that recognize and tag the data corresponding to the tenants. These tags are then recognized by data processing engines (DPEs) in the DPU such as AI engines, cryptographic engines, encryption engines, Direct Memory Access (DMA) engines, and the like. These DPEs can be configured to perform tag policies that provide security isolation and performance isolation between the tenants.
