One example embodiment provides a method and system where a node in a utility network receives a block of IPv6 network addresses from an access point in the utility network. The utility node allocates an IP network address from the block of IPv6 network addresses received from the access point to an in-premise device which communicates to the utility node over an in-premise network which is not IP based. The utility node proxies the allocated IP address to the utility network, allowing other nodes on the utility network to address and communicate with the in-premise device.

Method and system of providing network addresses to in-premise devices in a utility network

The present invention provides for a system and method for data network control. Using a flow control system, embodiments of the present invention can analyze traffic flow volume and performance, incorporate usage, billing, and cost control data to yield an improved data network controller. Efficiency in data routing is improved while costs are decreased by enabling the selection of the optimal performance data route. Cost constraints and costs are minimized for an overall data load. Given a diverse set of cost structures for available transit providers, the overall system cost can be minimized by distributing traffic in a manner that takes advantage of the diverse billing structures and yet maintains acceptable performance levels. Systems and methods in accordance with embodiments of the present invention determine projected flow performance and projected flow volume in relation to the available bandwidth and marginal cost to a destination provider.

Data network controller

A system and method for controlling routing of data. It is determined whether at least one data flow is active, the at least one data flow having an ingress portion of a current ingress path to a first point from a second point and an egress portion of a current egress path to the second point from the first point. Another data flow is routed via a next ingress portion of a next path to the first point from the second point.

System and method to provide routing control of information over networks

The present invention uses proxy points for measuring different routes to a destination address space. Multiple paths to the desired destination address space are identified. Each path begins at a source and terminates at the destination address space. Proxy points are identified for each path and are associated with a point between the source and the destination address space. Measurements of the path performance from each source to the appropriate proxy point are compared to determine an optimum route.

Topology aware route control

A method and system for maintaining a traffic service level for data communicated by a computer network having a source. The computer network is connected to at least one of many networks, where each of the many networks includes a number of paths for transporting the data communicated to a destination. In one embodiment of the method, the traffic service level associated with one of the paths between the source and the destination is monitored. Then, it is determined whether the traffic service level associated with that path meets one or more performance metrics. If a flow of data communicated over the monitored path fails to meet at least one of the performance metrics, then a service level violation is indicated. Upon such an indication, an alternate path is selected to resolve the service level violation.

System and method to assure network service levels with intelligent routing

A system and a method for controlling routing of data over multiple networks. Accordingly, network users can define specific flow polices to ensure that a particular flow of data traffic maintains an acceptable level of performance, such as in terms of latency, loss, jitter, or an acceptable level usage that includes cost and bandwidth management across multiple networks.
