Abstract: Some embodiments of the invention provide a method of upgrading a firewall module executing on a host computer to process traffic sent to and from machines executing on the host computer. While a first version of the firewall module executes on the host computer to process the traffic to and from the machines, the method loads a second version of the firewall module alongside the first version of the firewall module. For each of multiple ports associated with machines executing on the host computer for which the firewall module processes traffic sent to and from the port, the method saves a runtime state of the first version that relates to the port, transfers association of a firewall filter associated with the port from the first version to the second version, and restores the saved runtime state for the port to the second version.

Abstract: Some embodiments of the invention provide a method of upgrading software defined networking (SDN) modules executing on a host computer. While a first version of the SDN modules is executing on the host computer to perform traffic processing, the method loads a second version of the SDN modules alongside the first version of the SDN modules such that the first and second versions of the SDN modules are executing on the host computer at the same time. The method saves runtime states from the first version of the SDN modules, and transfers responsibility for performing traffic processing from the first version of the SDN modules to the second version of the SDN modules. The method then restores the saved runtime states to the second version of the SDN modules.
