Systems and methods for providing full redundancy in a computing network using a single network interface controller (NIC) and a single NIC card within one or more computing devices (e.g., servers) are provided. Embodiments of the technology disclosed herein provide a NIC card with a processing device (e.g., a field-programmable gate array (FPGA)) having a first set of input pins associated with a primary network switch and a second set of input pins associated with a standby network switch. When a failure occurs on the primary network switch, the processing device of the NIC card is configured to perform a circuit switch action to switch the connection between a processing device output from the first set of input pins to the second set of input pins. Accordingly, the same NIC is capable of controlling the network interface of a computing device between to different network switches.
