Abstract

Examples described herein includes a network interface controller comprising a memory interface and a network interface, the network interface controller configurable to provide access to local memory and remote memory to a requester, wherein the network interface controller is configured with an amount of memory of different memory access speeds for allocation to one or more requesters. In some examples, the network interface controller is to grant or deny a memory allocation request from a requester based on a configuration of an amount of memory for different memory access speeds for allocation to the requester. In some examples, the network interface controller is to grant or deny a memory access request from a requester based on a configuration of memory allocated to the requester. In some examples, the network interface controller is to regulate quality of service of memory access requests from requesters.

Dependent claims

An apparatus comprising:

a network interface controller comprising a direct memory access (DMA) circuitry, a memory interface, and a network interface, the network interface controller configurable to provide access to a first memory and a second memory, wherein:
the network interface controller is configured with amounts of memory in the first memory and the second memory associated with different memory access speeds for allocation to one or more requesters based on class of service of the one or more requesters,
a first amount of memory in the first memory is associated with a first class of service and first memory access speed,
a second amount of memory in the second memory is associated with a second class of service and second memory access speed,
the first class of service is higher than the second class of service,
the first memory access speed is higher than the second memory access speed,
the network interface controller is to access the first memory using the memory interface, and
the network interface controller is to access the second memory by transmission or receipt of Ethernet packets.

5 more elements

enable or disable a network interface device to:
manage access to a first memory and a second memory granted to a requester, wherein
the network interface device is configured with amounts of memory in the first memory and the second memory associated with different memory access speeds for allocation to one or more requesters based on class of service of the one or more requesters,
the network interface device comprises a direct memory access (DMA) circuitry, a memory interface, and network interface,
a first amount of memory in the first memory is associated with a first class of service and first memory access speed,
a second amount of memory in the second memory is associated with a second class of service and second memory access speed,
the first class of service is higher than the second class of service,
the first memory access speed is higher than the second memory access speed,
the network interface device is to access the first memory using the memory interface, and
the network interface device is to access the second memory by transmission or receipt of Ethernet packets.
