Abstract: A method of estimating power consumption of one or more network connected devices configured within an information technology (IT) architecture includes monitoring network events occurring within the IT architecture over a defined time period; correlating the monitored network events with predetermined power profile operating point data associated with the one or more network connected devices, wherein the power profile operating point data is based on possible network event occurrences within the IT architecture; and based on the correlating, generating an estimated energy usage of the one or more network connected devices for the defined time period.

Abstract: A method, article of manufacture, and system for indicating underutilized network devices that provide services in a data communications network. The method includes: receiving network traffic data; filtering the network traffic data to eliminate data for predefined connections; producing, from the filtered network traffic data, a graph representing a connection between a first device and a second device within the data communications network; analyzing the graph to identify a set of interconnected nodes that is outside the data communications network; and indicating an underutilized network device by producing an output dependent on traffic rate data associated with a link to the identified set of interconnected nodes that is outside the data communications network.

Abstract: Techniques are disclosed for discovery and tracking of locations of devices attached to a computing system network. By way of example, an automated method for determining a location of a target element in a distributed network includes the following steps. One or more locations of one or more sample topology elements in the distributed network are learned. Location mappings are generated, the location mappings representing associations between the learned locations of the one or more sample topology elements and one or more network attributes. A location of a target element is estimated using the location mappings.

Abstract: A system and method for mapping a network. Specifically, the present invention provides a non-intrusive system and method for identifying network attached devices as well as the details thereof. Under the present invention, a collection apparatus having collection tools is communicated with the network. The collection tools are operated to collect information from the devices. The device information is then analyzed to identify details of the devices. Once identified, the details are aggregated into a report.

Abstract: In an infrared communication system in which many units of different requirements can communicate with each other, transceivers are assigned to different categories, each with its own transmitting power and receiving sensitivity depending on the required distance range. This allows simultaneous independent infrared communications in different local areas between low power/sensitivity devices but enables also transmission over larger distances or over the whole system between larger power/sensitivity devices. Depending on the power/sensitivity relation and distance, a potential receiver may either be able to decode data signals correctly, or it may be only able to detect the presence of a carrier. To allow a clear access protocol in all cases, a unit gets two chances to reenter access competition after having sensed the carrier: Either upon decoding a data end delimiter, or upon a timeout equal to the longest possible packet transmission time.
