  • System and method for managing computer networks
    Patent number: 8667047
    Abstract: A system and method are provided for monitoring traffic in an enterprise network. Similar hosts may be grouped using flow information. Network policy may then be created at the group level based on the signatures of the hosts and groups of hosts in the enterprise. Hosts may be arranged in hierarchical clusters. Some of these clusters may be selected as groups based on a desired degree of similarity between hosts in a group. The similarity between hosts may be determined based on similarity of network behavior of the hosts.
    Type: Grant
