Method for managing firewall cluster in network computing environments, systems, and computer program (firewall clustering regions in a network computing environment)

摘要

[problem] virtual / network (for example, cloud) for carrying out the optimal state share in a different site in a computing environment, to provide a method for the firewall clustering of the region. In A standard embodiment, each firewall in a particular region, is notified of the peer firewall through the registration process to the central management server. Each firewall, open the Internet Protocol (IP) based communication channel to each peer in the region, to share a state table information. Thus, asymmetric firewall flow through the network allows, even without considering the arrangement of the firewall, it is possible to determine the best route to a particular destination in the routing protocol.FIELD 6
