In general, embodiments of the invention relate to processing network traffic data units (NTDUs). More specifically, embodiments of the invention relate to processing NTDUs transmitted between client device and the one or more protected resources. The protected resources are logically surrounded by a perimeter, which is implemented as a set of network devices that manage the flow of NTDUs between client devices and the protected resources. The perimeter works in conjunction with a set of filtering devices to determine whether a given NTDU can ultimately be transmitted to, and processed by, a protected resource.

Embodiments of the invention may relate to method. In one or more embodiments of the invention, the method includes receiving, by a network device, a command to initiate a control plane reboot. The method may also include extracting, based on the command, a transitional update database from a software image that includes a new software version and the transitional update database. The method may also include performing a query to determine whether the transitional update database includes a required transitional update for performing an upgrade to the new software version; installing, when the query determines that the required transitional update is included in the software image, the required transitional update; and performing, after installation of the transitional update is complete, the control plane reboot to complete the upgrade to the new software version.
