摘要:
A method and system for enabling a network service provider to monitor a packet network by using call detail records (CDRs) are disclosed. The method first detects a termination of a call by at least one voice gateway router and generates a call detail record (CDR) at said termination of said call by said at least one voice gateway router. The method then forwards said call detail record by said at least one voice gateway router to at least one CDR collecting and analysis server.

An open communication method between at least two sub-networks using a broker node. Each of the sub-networks has a different routable network addressing scheme. The method comprises receiving a packet for a specific application, the packet includes an application identifier, determining if the packet is to be relayed to another of the at least two sub-networks based upon the application identifier, determining if a node receiving the packet is a broker node, relaying the packet to a broker node if not a broker node and forwarding, by the broker node, the packet to at least one node in another of the at least two sub-networks. The node generating the packet communicates using a first of the at least two sub-networks. A broker node communicates using at least two of the at least two sub-networks via a corresponding routable network addressing schemes for each of the sub-networks.

A method for defining patterns in an integrated circuit comprises defining a plurality of features in a first photoresist layer using photolithography over a first region of a substrate. The method further comprises using pitch multiplication to produce at least two features in a lower masking layer for each feature in the photoresist layer. The features in the lower masking layer include looped ends. The method further comprises covering with a second photoresist layer a second region of the substrate including the looped ends in the lower masking layer. The method further comprises etching a pattern of trenches in the substrate through the features in the lower masking layer without etching in the second region. The trenches have a trench width.

A system for determination of the functionality of an audio-related device that is operable in an audio system includes a performance equipment manager. The performance equipment manager may receive from an audio-related device an audio node structure representative of the corresponding audio-related device. The received audio node structure may be reviewed to determine if all the components included in the audio node structure are predefined within the performance equipment manager. For those components that are known, no discovery is necessary and actual values of changeable parameters in the audio-related device may be obtained. For unknown components of the audio node structure, the performance equipment manager may undertake discovery to identify additional portions of the audio node structure, and/or attributes related to the unknown components, in order to obtain actual values of changeable parameters related to the unknown components.
摘要:
Without using additional probing packets, estimates of the narrow link bandwidth and available bandwidth of a network path are computed based on existing traffic. The network can be of different types such as a wireless battlefield network context or a wired or wireless commercial network environment. “Fast packets”, i.e. those packets which do not experience any queuing delay in the network, are identified. Fast packets are identified to resolve end-to-end packet delay into its constituent components (deterministic, transmission and queuing delays), estimate path utilization and eliminate the uncertainty (false alarms) that causes the prior art method to lose its effectiveness. An estimation algorithm computes end-to-end transmission delay and end-to-end deterministic delay of fast packets traveling along a path in a network. Examples of deterministic delay include satellite propagation delays and clock effects. Then, based on the results of the fast packet identifying algorithm, two logic branches are followed. A first branch calculates utilization and a second branch calculates narrow link bandwidth. The narrow link bandwidth is determined from the packet pair dispersion. The available bandwidth is obtained from the narrow link bandwidth and the utilization. Estimation of available bandwidth for an end-to-end network path allows traffic sources to judiciously regulate the volume of application traffic injected into the network.

The solar-based power generator (10) is a system for producing usable electricity from water, which is heated through concentration of ambient, environmental light. The generator (10) includes a reservoir (12) having an open upper end. The reservoir (12) receives a volume of water (14) therein. A convex lens (16) is mounted on an upper edge of the reservoir (12). The convex lens (16) covers the open upper end. A steam output port (11) is in fluid communication with a steam-based electrical generator (18). The convex lens (16) concentrates ambient light on the water (14) stored within the reservoir (16), thus heating the water (14) and converting the liquid water to steam. Additionally, a methane-burning electrical generator (24) is in communication with the reservoir (12). Pollutants in the water (14) produce methane during heating and decomposition, which is burned by the methane-burning electrical generator (24).
摘要:
A system for management and control of audio-related equipment. The system is a common architecture that provides the capability to manage, monitor and control all of the audio-related equipment in an audio system. To facilitate messaging between audio-related devices, each of the audio-related devices may be assigned a node ID a sequential manner as each audio-related device powers up. The system may also include a method for discovery of audio-related devices on an audio network. In some examples, a PEM may be located geographically remote from the audio-related devices. Accordingly, error logging, alarming and system operation may be monitored to provide troubleshooting from a remote location.
摘要:
A system for communication among audio-related devices in an audio system includes a performance equipment manager that communicates with audio-related devices to monitor and control changeable parameters of a corresponding audio-related device. Each of the audio-related devices includes an audio node structure having components that are representative of the functionality of the respective audio-related device. Some of the components are representative of changeable parameters in the audio-related device. The performance equipment manager is configured to be selectively subscribed to one or more of the changeable parameters so that when a predefined condition occurs, the audio-related device is configured to automatically provide the current value of the changeable parameter(s) to the performance equipment manager.
