Skypoint for mobile hotspots

A system and method for dynamically planning a network is presented. One method may begin by determining network parameters for connecting nodes to a network and decision variables associated with radios and / or nodes in the network. Constraints may be established to narrow possible values of the network parameters and / or the decision variables. The constraints may be based on one or more of: values associated with connecting a radio to a node in the network, values associated with connecting two nodes in the network together over a communication link, whether a node can connect to a GIG node and a flow balance in the GIG node. To find possible links in the network that are optimal, the method may minimize an equation based on the network parameters, constraints and decision variables to determine optimal communication links between pairs of nodes in the network, pairs of nodes and radios and / or pairs of radios.

ActiveUS20110131017A1Accurately solves massAccurately flow balanceProgramme controlAnalogue computers for control systemsMass storageParallel computing
A high fidelity distributed plant simulation technique includes a plurality of separate simulation modules that may be stored and executed separately in different drops or computing devices. The simulation modules communicate directly with one another to perform accurate simulation of a plant, without requiring a centralized coordinator to coordinate the operation of the simulation system. In particular, numerous simulation modules are created, with each simulation module including a model of an associated plant element and these simulation modules are stored in different drops of a computer network to perform distributed simulation of a plant or a portion of a plant. At least some of the simulation modules, when executing, perform mass flow balances taking into account process variables associated with adjacent simulation modules to thereby assure pressure, temperature and flow balancing (i.e., conservation of mass flow) through the entire simulation system. In a dynamic situation, a transient mass storage relay technique is used to account for transient changes in mass flow through any non-storage devices being simulated by the simulation modules. Moreover, adjacent simulation modules located in different drops communicate directly with one another using a background processing task, which simplifies communications between adjacent simulation modules without the need for a central coordinator.

Combining multilink and IP per-destination load balancing over a multilink bundle

Load balanced transport of best efforts traffic together with delay-bounded traffic over a multilink bundle combines fragmentation and fragment distribution for best efforts packets with per-flow balancing for delay-bounded traffic. In the preferred embodiments, the best efforts packets receive Multilink Protocol treatment, including fragmentation and addition of sequence headers. Fragments of packets for one such communication go over the various links within the bundle, as appropriate for load balancing on the links. For each delay-bounded flow, such as for a VOIP service, the sending node hashes the packet header data and applies all packets for the flow to one of the links, assigned as a function of the hash value. Different flow headers produce different hash results; therefore the node sends different flows over the different links in a substantially balanced manner.

Method for controlling traffic balance between peering networks

A method that measures ratio, relative to a peering network, of traffic burden of incoming traffic to traffic burden of outgoing traffic, where traffic burden takes into account traffic volume and distance that the traffic traverses through the network. A determination is made from this ratio as to whether an imbalance exists with the peering network. With the assistance of a simulation of changes in routing policy and their effects, an existing or impending imbalance is remedied by changing the routing policy relative to particular customers, for example from a “hot potato” routing policy to a “best exit” routing policy.

The system applies a utilization metric to determine how much capacity a given task has available and uses this determination to determine the capacity available for the cluster as a whole. Load balancing is achieved by re-directing queries to another cluster in response to the utilization value for a given cluster reaching a threshold.
