1. A method, comprising:
storing, by a device, current traffic data received from a primary processing component as residual data associated with a backup processing component;
incrementing, by the device, a counter when a packet, from host transmitted traffic data generated by the primary processing component, is forwarded to the backup processing component;
removing, by the device, the host transmitted traffic data from the residual data when the host transmitted traffic data is larger than a threshold;
performing, by the device, a switchover from the primary processing component to the backup processing component to cause the backup processing component to operate as the primary processing component; and
determining, by the device and based on performing the switchover, switchover traffic data based on reading the counter and modifying the residual data with the host transmitted traffic data.
