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.
