Dynamic transmission side scaling

An apparatus comprising:

• a plurality of transmit queues associated with a network interface;
• a plurality of threads for user plane functions, a number of said threads exceeding a number of the transmit queues;
• a processor for assigning a portion of said plurality of threads to a corresponding number of transmit queues, assigning remaining threads to software transmission queues associated with the threads assigned to the transmit queues, identifying a load at each of the threads, and dynamically updating assignment of the threads to said software transmission queues based on the load at the threads;
• memory for storing a mapping of the threads to said software transmission queues;
• and
• a physical interface for transmitting packets from the transmit queues to a network.

Logic encoded on one or more non-transitory computer readable media for execution and when executed operable to:

• assign a number of threads for user plane functions to a corresponding number of transmit queues for transmission of packets on a network interface;
• assign a plurality of additional threads exceeding the number of transmit queues to software transmission queues associated with the threads assigned to the transmit queues;
• identify a load at each of the threads assigned to the transmit queues;
• dynamically update assignment of said additional threads to said software transmission queues based on the load at the threads;
• and
• transmit packets from the transmit queues for transmission on a network from a physical interface at a network device.
