PACKET PROCESSING CONFIGURATIONS
Examples described herein relate to an interface and a network interface device coupled to the interface and comprising circuitry. In some examples, the circuitry is to receive packet data to be egressed, wherein the packet data does not specify a destination for the packet data and process the packet data to be egressed to generate a mapping of ingress packet-to-target based on a determination.
1 . An apparatus comprising:
an interface and
a network interface device coupled to the interface and comprising circuitry to:
receive packet data to be egressed, wherein the packet data does not specify a destination for the packet data and
process the packet data to be egressed to generate a mapping of ingress packet-to-target based on a determination.
2 . The apparatus of claim 1 , wherein the determination comprises a type of packet data or content of a descriptor.
3 . The apparatus of claim 1 , wherein the determination comprises content of a descriptor and wherein the descriptor is to identify one or more fields of a the packet data that comprise content to include in the mapping.
4 . The apparatus of claim 3 , wherein the descriptor is to specify a depth of the received packet to process to determine a processor to process the received packet.
5 . The apparatus of claim 1 , wherein the packet data to be egressed comprises a Linux® eXpress Data Path (XDP) raw frame.
6 . The apparatus of claim 1 , wherein the circuitry comprises a packet parser to process the packet data to generate the mapping of received packet-to-target.
7 . The apparatus of claim 1 , wherein
based on receipt of a packet, access the mapping to determine a processor to process the received packet and provide received packet to a queue associated with determined processor.
8 . The apparatus of claim 1 , wherein the network interface device comprises one or more of: a network interface controller (NIC), a remote direct memory access (RDMA)-enabled NIC, SmartNlC, router, switch, forwarding element, infrastructure processing unit (IPU), or data processing unit (DPU).
9 . The apparatus of claim 1 , comprising a server, wherein the server is to execute a driver to cause generation of the mapping.
10 . The apparatus of claim 9 , comprising a data center comprising the server and a second server, wherein the network interface is to transmit the packet to the second server and direct a packet received from the second server to a target process based on the mapping of received packet-to-target.
11 . A non-transitory computer-readable medium comprising instructions stored thereon, that if executed by one or more processors, cause the one or more processors to:
execute a driver to
based on transmission of a frame without destination metadata, generate a descriptor to cause parsing of the frame to update an association of packets to one or more queues.
12 . The computer-readable medium of claim 11 , wherein data of the frame comprises a Linux® eXpress Data Path (XDP) raw frame.
13 . The computer-readable medium of claim 11 , wherein the descriptor is to cause a packet parser to process data of the frame based on the descriptor to generate the packets to one or more queues.
14 . The computer-readable medium of claim 11 , wherein the descriptor is to identify one or more fields of a the packet data that comprise content to include in the association of packets to one or more queues.
15 . The computer-readable medium of claim 11 , wherein the descriptor is to specify a depth of a received packet to process to determine the processor to process the received packet.
16 . A method comprising:
receiving packet data that does not specify a destination for the packet data;
receiving a descriptor associated with the packet data; and
processing the packet data based on the descriptor to generate a mapping of received packet-to-target.
17 . The method of claim 16 , wherein the packet data comprises a Linux® eXpress Data Path (XDP) raw frame.
18 . The method of claim 16 , wherein a packet parser performs the processing the packet data based on the descriptor to generate a mapping of received packet-to-target.
19 . The method of claim 16 , wherein the descriptor is to identify one or more fields of a the packet data that comprise content to include in the mapping.
20 . The method of claim 16 , comprising:
based on receipt of a packet, accessing the mapping to determine a processor to process the received packet and provide received packet to a queue associated with determined processor.
