Abstract
A method for processing packets in a computer undergoing transitioning from a first configuration of a firewall to a second configuration of the firewall is disclosed. Packets arriving in the computer are associated with the first configuration of the firewall existing in the computer, and after a second configuration of the firewall becomes available, the computer starts associating packets arriving in the computer with the second configuration of the firewall, and processing packets associated with the second configuration according to the second configuration of the firewall, while continuing processing the packets associated with the first configuration according to the first configuration of the firewall until all packets associated with the first configuration are processed. Packets are processed by a plurality of firewall processing modules asynchronously. First and second reference counts, counting numbers of packets processed according to respective firewall configuration are conveniently introduced. A corresponding system is also provided.
