Publication number: 20230362284Abstract: Technologies for programming flexible accelerated network pipelines include a comping device with a network controller. The computing device loads a program binary file that includes a packet processing program and a requested hint section. The binary file may be an executable and linkable format (ELF) file with an extended Berkeley packet filter (eBPF) program. The computing device determines a hardware configuration for the network controller based on the requested offload hints and programs the network controller. The network controller processes network packets with the requested offloads, such as packet classification, hashing, checksums, traffic shaping, or other offloads. The network controller returns results of the offloads as hints in metadata. The packet processing program performs actions based on the metadata, such as forwarding, dropping, packet modification, or other actions. The computing device may compile an eBPF source file to generate the binary file.Type: ApplicationFiled: June 23, 2023Publication date: November 9, 2023Inventors: Peter P.

Publication number: 20230056330Abstract: Methods and apparatus for two-layer Alpha-based buffer management with dynamic RED. A two-layer hierarchical sharing scheme using alpha parameters is provided. A buffer is dynamically shared across upper-level entities, such as hosts, using one set of alpha parameters, then a dynamically-adjusted buffer portion allocated for an upper level entity is shared among its lower level entities (e.g., sub queues) using a separate set of low-level alpha parameters. The memory spaces for the upper- and lower-level entities may be dynamically redistributed. Determinations to drop and/or mark and ECN field of received packets are performed using Dynamic RED, which employs dynamic thresholds and associated dynamic probabilities.Type: ApplicationFiled: October 18, 2022Publication date: February 23, 2023Applicant: Intel CorporationInventors: Sarig LIVNE, Nrupal JANI, Eli SHAPIRO, Parthasarathy SARANGAM, Neerav PARIKH

Patent number: 11467873Abstract: Technologies for remote direct memory access (RDMA) queue pair quality of service (QoS) management are disclosed. In the illustrative embodiment, several queue pairs associated with a virtual machine on a compute sled may be created in a network interface controller of the compute sled. A QoS parameter such as a class of service identifier or a weighting may be assigned to each queue pair such that each queue pair has a different available bandwidth. The compute sled may also predict future RDMA queue pair bandwidth usage and adjust RDMA queue pair bandwidth allocation based on the prediction.Type: GrantFiled: July 29, 2019Date of Patent: October 11, 2022Assignee: Intel CorporationInventors: Mrittika Ganguli, Neerav Parikh, Robert Sharp, Sujoy Sen

Patent number: 11403137Abstract: Tenant support is provided in a multi-tenant configuration in a data center by a Physical Function driver communicating a virtual User Priority to a virtual traffic class mapper to a Virtual Function driver. The Physical Function driver configures the Network Interface Controller to map virtual User Priorities to Physical User Priorities and to enforce the Virtual Function's limited access to Traffic Classes. Data Center Bridging features assigned to the physical network interface controller are hidden by virtualizing user priorities and traffic classes. A virtual Data Center Bridging configuration is enabled for a Virtual Function, to provide access to the user priorities and traffic classes that are not visible to the Virtual Function that the Virtual Function may need.Type: GrantFiled: October 7, 2019Date of Patent: August 2, 2022Assignee: Intel CorporationInventors: Manasi Deval, Neerav Parikh, Robert O.

Publication number: 20200099628Abstract: The present disclosure is directed to systems and methods for rate limiting network traffic generated by virtual machines (VMs) having multiple attached SR-IOV virtual functions. The network interface circuitry includes a plurality of offload circuits, each performing operations associated with a specific VF. Each VM attached to network interface circuitry is assigned a unique identifier. The unique identifier associated with a VM is inserted into the header of data packets originated by the VM. The packets are queued using a dedicated memory queue assigned to the VM. The aggregate data transfer rate for the VM is determined based upon counting the data packets originated by the VM and processed across the plurality of offload circuits. If the aggregate data transfer rate exceeds a data transfer rate threshold, traffic control circuitry limits the transfer of data packets from the memory queue associated with the VM to the plurality of offload circuits.Type: ApplicationFiled: November 27, 2019Publication date: March 26, 2020Applicant: Intel CorporationInventors: Neerav Parikh, Nrupal Jani
