Abstract

Techniques are disclosed for a smart network interface card (smartNIC) performing a unified logging process. In one example, an accelerator of the smartNIC receives a packet that is a candidate for rejection, whereby the accelerator is configured to log traffic for authorized flows that are forwarded by the accelerator to another device. The accelerator transmits the packet to a programming data plane of the smartNIC for further processing. The programming data plane determines that the packet should not be forwarded by the smartNIC, and modifies the packet to include an instruction that instructs the accelerator to log the packet. The programming data plane then transmits the modified packet to the accelerator. Upon receiving the modified packet, the accelerator logs the packet to the unified log based on the instruction.

Claims20

Dependent claims

A computer-implemented method, comprising:

receiving, by an accelerator of a smart network interface card (SmartNIC), a packet that is intended for forwarding by the smart network interface card to another device;
determining, by the accelerator, that the packet is a candidate for rejection based at least in part on the packet not being associated with an authorized flow, the accelerator being configured to log traffic to a unified log for authorized flows that are forwarded by the accelerator;
transmitting, by the accelerator, the packet to a programming data plane of the smart network interface card;
determining, by the programming data plane, whether the packet should be forwarded;
and
in accordance with a determination that the packet should not be forwarded:
modifying, by the programming data plane, the packet to include an instruction that instructs the accelerator to log the packet and to not forward the packet;
transmitting, by the programming data plane, the modified packet to the accelerator;
and
logging, by the accelerator, data associated with the modified packet to the unified log based at least in part on the instruction.

7 more elements

A smart network interface card (smartNIC), comprising:

a programming data plane comprising a first set of one or more processors of a plurality of processors;
an accelerator comprising a second set of one or more processors of the plurality of processors and a cache;
and
a memory comprising computer-executable instructions that, when executed by one or more of the plurality of processors, cause the smart network interface card to:
receive, by the accelerator, a packet that is intended for forwarding by the smart network interface card to another device;
determine, by the accelerator, that the packet is a candidate for rejection, the accelerator being configured to log traffic to a unified log for authorized flows that are forwarded by the accelerator;
transmit, by the accelerator, the packet to the programming data plane;
modify, by the programming data plane, the packet to include an instruction that instructs the accelerator to log the packet;
transmit, by the programming data plane, the modified packet to the accelerator;
and
log, by the accelerator, data associated with the modified packet to the unified log based at least in part on the instruction.

8 more elements

One or more non-transitory computer-readable storage media comprising computer-executable instructions that, when executed by one or more processors of a smart network interface card (smartNIC), cause the one or more processors to:

receive, by an accelerator of the smart network interface card, a packet that is intended for forwarding by the smart network interface card to another device;
determine, by the accelerator, that the packet is a candidate for rejection, the accelerator being configured to log traffic to a unified log for authorized flows that are forwarded by the accelerator;
transmit, by the accelerator, the packet to a programming data plane of the smart network interface card;
modify, by the programming data plane, the packet to include an instruction that instructs the accelerator to log the packet;
transmit, by the programming data plane, the modified packet to the accelerator;
and
log, by the accelerator, data associated with the modified packet to the unified log based at least in part on the instruction.
