  • Patent number: 9325719
    Abstract: A network analysis tool is provided in support of a data communication network having user devices at indeterminate endpoints wherein user identities, namely, the collection of meta-data about a user device of a network (beyond the conventional networking concept of an endpoint address), is modeled as fixed endpoints for purposes of tracking. More specifically, users at indeterminate endpoints are identified by modeling using user roles as models of the user devices.

  • Patent number: 9325741
    Abstract: A network analysis tool is provided in support of a data communication network having dynamically provisioned devices at indeterminate endpoints wherein templates, namely, the collection of meta-data about dynamically provisioned devices on a network (beyond the conventional networking concept of an endpoint address), are modeled as fixed endpoints for purposes of tracking. In a specific embodiment, template groups are generated as network interfaces for a modeled template enforcement device, and template groups are represented as if they are network endpoints connected to a template enforcement device, and a device description for the template enforcement device is produced.

  • Patent number: 8479257
    Abstract: An as-built network is evaluated by analyzing a model of the network by the steps of determining zones within the network, computing the access between zones, summarizing the access between zones to produce a dataset, then inputting a policy set comprising a collection of approvals, typically in the form of simple white-lists of approvals, then comparing the dataset and particularly the access between zones with the policy set of approvals (white-lists) to determine which access fall outside the approvals, and producing therefrom as an output to an end user a report of compliance and noncompliance, and then repeating the steps of determining, computing, and summarizing, and then the comparing step, after a period or after the network has changed. Thus a network operator or auditor can readily and interactively assess whether the infrastructure is in compliance with regulatory or other design requirements.

  • Patent number: 8051481
    Abstract: The present invention is directed to methods of and systems for adaptive networking that monitors a network resource of a network. The method monitors an application performance. The method categorizes a first subset of traffic of the network. The categories for the first subset include trusted, known to be bad, and suspect. The method determines an action for a second subset of traffic based on the category for the first subset of traffic. Some embodiments provide a system for adaptive networking that includes a first device and traffic that has a first subset and a second subset. The system also includes a first resource and a second resource for the transmission of the traffic. The first device receives the traffic and categorizes the traffic into the first and second subsets. The first device assigns the first subset to the first resource.

  • Patent number: 8023421
    Abstract: A system for the assessment of network performance criteria, and applying this criteria to the classification of network addresses into appropriate ranges, using these ranges to consolidate performance measurements for the associated addresses, and applying these metrics toward the optimization of the network towards performance or policy objectives.

  • Patent number: 7840704
    Abstract: Systems and methods are described for supporting routing intelligence for evaluating routing paths based on performance measurements. The routing intelligence may include processes executed in a self-contained device. This device may control one or more edge routers, based on performance data from end users. In other embodiments, the routing intelligence device may be used solely to monitor one or more edge routers, producing reports but not effecting any changes to routing. Routing decisions may be injected to the edge routers via BGP updates. The devices may be stationed at the premises of a multihomed organization, such as an enterprise, ISP, government organization, university, or other organization supporting a sub-network coupled to an internetwork. In other embodiments, the routing intelligence comprises processes executed on a router.

  • Patent number: 7675868
    Abstract: Systems and methods are described for enabling routers to coordinate via a back-channel communication medium. The information exchanged over the back-channel is used to increase the number of paths considered for the routers during route optimization. The Decision Makers may assert routes and prefixes to the routers under their control. This may be done via a Border Gateway Protocol (BGP) feed. The Decision Makers, in turn, communicate separately with one another, in order to coordinate routing policy amongst themselves. This coordination may be performed over a back-channel, which may take the form of physical or logical connections between the Decision Makers.

  • Patent number: 7487237
    Abstract: Methods, computer code, and means are described that can control load in a network. In some applications, the monetary cost of operating the network can be reduced. Utilization of links in the network can be monitored. A degree of suboptimality with respect to some criteria can be assessed. In some instances, the criteria could be based at least partly one or more monetary billing structures of some subset of two or more links. A subset of the forwarding decisions of one or more forwarding nodes in the network can be adjusted automatically, based at least partly on the assessing. The adjustment can attempt to reduce the degree of suboptimality.
