Method to improve packet rate using packet bundle mode to transmit a vector of packets in a single job

A network interface controller (NIC) configured to bundle multiple data packets in a single transmission job, wherein each of the packets comprises a header and a payload, the NIC comprising:

• an application software module configured to:
• create a job descriptor for the single transmission job based on at least one of a packet mode for the single transmission job and a bundling mode for the single transmission job, the job descriptor comprising a pointer to a read DMA section, the read DMA section including at least one read DMA command for fetching all of the data packets;
• and
• store the job descriptor in a memory device;
• and
• a physical layer scheduler module (PSM), wherein the PSM receives from the application software module a job command associated with the job descriptor job, the PSM configured to enqueue the job command;
• and
• a transmit module configured to receive the job command from the PSM and, subsequent to receipt of the job command:
• retrieve the job descriptor from the memory device;
• execute the at least one DMA command to fetch all of the data packets;
• transmit the data packets via a data communications system in accordance with the at least one of the packet mode and the bundling mode;
• and
• return a job completion event to the software module subsequent to the transmitting;
• wherein N is greater than 1 and less than or equal to 16.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to implement operations for bundling N data packets in a single job for transmission via a data communications system, wherein each of the data packets comprises a header and a payload, the operations comprising:

• creating a job descriptor for the single transmission job based on at least one of a packet mode for the single transmission job and a bundling mode for the single transmission job, the job descriptor comprising a pointer to a read DMA section, the read DMA section including at least one read DMA command for fetching all of the data packets;
• storing the job descriptor in a memory device;
• enqueuing a job command associated with the job descriptor job to a hardware scheduler;
• processing the job command by a transmission module, the processing comprising:
• retrieving the job descriptor from the memory device;
• executing the at least one DMA command to fetch all of the data packets;
• transmitting the data packets via the data communications system in accordance with the at least one of the packet mode and the bundling mode;
• and
• returning a job completion event subsequent to the transmitting.
