International Classification:

G06F 15/16

US Classification:

709250, 709238

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.

International Classification:

G06F 15/173

US Classification:

709240, 370238, 370254, 37039531

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.

International Classification:

G06F 15/173
G06F 9/46

US Classification:

709224, 718105

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.

US Classification:

726 24, 726 25, 713154, 370230, 370231, 709224

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. Some embodiments provide a network device that includes an input for receiving incoming traffic, an output for sending outgoing traffic, a categorization module that categorizes incoming traffic, and a resource assignment module that assigns the categorized traffic for a particular resource.
