Abstract
In general, techniques are described for providing software redundancy for Virtual Network Functions (VNF). In one example, a method includes, by a host process executed by an insertable service card of a network device, pinning, to a plurality of hardware-based processors, active threads of an active network function. The host process pins, to a single hardware-based processor, backup threads of a backup network function for the active network function, wherein the plurality of hardware-based processors does not include the single hardware-based processor. The host process pins, to the single hardware-based processor, management threads of the active and backup network functions. The single hardware-based processor executes the management threads of the active and backup network functions to cause the management thread of the backup network function to receive, from the management thread of the active network function, state data generated by the active threads.
