A meshing network comprising one full function controller (WDC) and a plurality of nodes (WDN, WSN), that is RF quiet capable with very low power consumption and the ability to quickly heal itself and create new network paths. The network uses an addressing scheme that allows for each node to not have a network map but still be able to route messages. A piping scheme allows a mesh to become a high throughput network. A sensor rail protocol definition allows sensor devices to connect to nodes and route messages through the network.

Automatic white balancing and/or autoexposure as useful in a digital camera extracts color channel gains from comparisons of image colors with reference colors under various color temperature illuminants and/or extracts exposure settings from illuminance mean, illuminance variance, illuminance minimum, and illuminance maximum in areas of an image with a trained neural network.

A client player performs a query to a nameserver against a network map of Internet traffic conditions. The query is made asking for a particular service (e.g., RTSP) via a particular protocol (TCP) in a particular domain. In response, the nameserver returns a set of one or more tokens, with each token defining a machine or, in the preferred embodiment, a group of machines, from which the player should seek to obtain the stream. The player may then optionally perform one or more tests to determine which of a set of servers provides a best quality of service for the stream. That server is then used to retrieve the stream. Periodically, the client player code repeats the query during stream playback to determine whether there is a better source for the stream. If a better source exists, the player performs a switch to the better stream source “on the fly” if appropriate to maintain and/or enhance the quality of service. Preferably, the client player publishes data identifying why it selected a particular server, and such data may be used to augment the network map used for subsequent request routing determinations.

A policy component comprises policy configuration information. The policy configuration information contains one or more rules. Each rule and group of rules can be associated with a set of response actions. As the nodes on the monitored networks change or intrusive actions are introduced on the networks, network change events or intrusion events are generated. The policy component correlates network change events and/or intrusions events with network map information. The network map contains information on the network topology, services and network devices, amongst other things. When certain criteria is satisfied based on the correlation, a policy violation event may be issued by the system resulting in alerts or remediations.

The architecture is desirably implemented in a proton beam therapy system to provide flexible security policies which improve patent safety and facilitate system maintenance and development.

Embodiments of systems, computer-implemented methods, and non-transitory computer-readable medium having one or more computer programs stored therein are provided to enhance borehole image analysis associated with a hydrocarbon reservoir. A neural network mapping process can first be performed, responsive to openhole log data and core data, to thereby generate a material-type scheme. Then, an image-based petrophysical analysis process can distribute and calibrate borehole image data, responsive to the core data and material-type scheme. Consequently, an approximated material type and an approximated grain size can be produced for each borehole image reading. The openhole log data, the core data, the material-type scheme, and the approximated material types and grain sizes, for example, can then be displayed to thereby increase consistency in categorizing subsurface material associated with hydrocarbon wells by material type and enhance interpretation of subsurface material texture, fabric, and features to predict subsurface material composition of the hydrocarbon reservoir.

Methods, devices, and systems are disclosed for simulating a large, realistic computer network. Virtual actors statistically emulate the behaviors of humans using networked devices or responses and automatic functions of networked equipment, and their stochastic actions are queued in buffer pools by a behavioral engine.

Using the ALTO Service, networking applications can request through the ALTO protocol information about the underlying network topology from the ISP or Content Provider. The ALTO Service provides information such as preferences of network resources with the goal of modifying network resource consumption patterns while maintaining or improving application performance. This document describes, in one example, an ALTO server that intersects network and cost maps for a first network with network and cost maps for a second network to generate a master cost map that includes one or more master cost entries that each represent a cost to traverse a network from an endpoint in the first network to an endpoint in the second network. Using the master cost map, a redirector may select a preferred node in the first network with which to service a content request received from a host in the second network.

The invention provides a particle-swarm-optimization-based virtual network mapping method and a particle-swarm-optimization-based virtual network mapping system. The method comprises the following steps of: initializing position and speed parameters of particles; performing feasibility checking on the particles to obtain feasible particles, and determining an initial global optimal position and individual optimal positions of each particle; performing speed and position updating on the feasible particles, performing the feasibility checking on the updated particles to obtain feasible particles again, determining a global optimal position and individual optimal positions again, adding 1 to a current number of iterations, and repeating the operations of the step when the number of iterations is less than a maximum number of iterations; and when the number of iterations is equal to the maximum number of iterations, outputting the finally determined global optimal position as a mapping scheme. By the method and the system, the position and speed parameters of a particle swarm are initialized under the condition that a bottom-layer network does not support path splitting, and the particles are iterated to select an optimal virtual network mapping scheme, so the resource utilization efficiency of the bottom-layer network is improved.

A trace detector prevents network mapping and tracing by detecting an initial packet containing an initial time to live value that meets a first predetermined threshold range. The trace detector identifies a source address of the initial packet and adjusts a threshold time to live range for detection of at least one subsequent trace route or response packet associated with the source address of the initial packet. In response to detecting the subsequent packet(s), the trace detector processes the subsequent packet(s) associated with the source address of the initial packet according to a security policy to prevent a trace process originating the initial packet from tracing a network using the at least one subsequent packet.

The failover of nodes within networks, using a multicast address or a multicast port, is disclosed. A first node of a network joins a multicast group having a multicast address, which is assigned to the first node. Communication to the first node is achieved via communication to the multicast address, and/or through a multicast port on a switch of the network mapping to a port on the first node. When the first node fails, one of two actions occurs. First, a second node of the network may join the multicast group, such that the multicast address is assigned to the second node, and the second node handles communication to the multicast address. Second, the multicast port on the switch may be remapped to a port on the second node, so that communication to the multicast address is directed to the port on the second node.
