Abstract: A network interface card (NIC) can be configured to monitor a first central processing unit (CPU) core mapped to a first receive queue having a receive queue length. The NIC can also be configured to determine whether the CPU core is overloaded based on the receive queue length. The NIC can also be configured to redirect data packets that were targeted from the first receive queue to the CPU core to another CPU core responsive to a determination that the CPU core is overloaded.

Abstract: Technologies for network application programming include a computing device that analyzes a network application source program. The source program includes a declarative description of a network application in a domain-specific language, such as P4. The computing device translates the declarative description of the network application into a register-transfer level (RTL) description, and then compiles the RTL description into a bitstream definition that is targeted to an FPGA. For example, the computing device may generate a parse graph based on the network application source program, and then generate an RTL TCAM-SRAM structure for each node of the parse graph. The computing device may optimize the RTL description, for example by simplifying RTL structures or removing unused logic. The computing device may program an FPGA with the bitstream definition. Other embodiments are described and claimed.
