Abstract: A method for energy consumption monitoring in an ICT environment, wherein the ICT environment (1) includes a multitude of energy consuming components (2, 3), at least partly the components (2, 3) being instrumented with elements for energy consumption monitoring and/or having assigned specific energy consumption models that derive one or more energy metrics for the respective component (2, 3) from the component's (2, 3) current performance metrics, is characterized in the steps of ascertaining changes of and/or related to the ICT environment (1) via an energy consumption monitoring controller (7), performing an assessment of available energy consumption monitoring techniques both instrumentation-based and model-based, based on the result of the assessment selecting one or more energy consumption monitoring techniques that best satisfy the change of the ICT environment (1) according to predefined policies. Furthermore, a corresponding monitoring system is described.

Abstract: A method for transferring time-synchronous data, particularly voice and video data, over a network, particularly the Internet, between at least two terminals, where between the terminals a connection is established using a SIP server and where the SIP protocol is used for establishing the connection, is—with respect to high Quality of Service for transferring time-synchronous data and with a technically simple and cost effective design—developed in a way that the SIP server analyzes the connection and/or the terminals or the like and that based on the analysis it determines an ideal bandwidth for optimizing the transfer of time-synchronous data.

Abstract: A method of monitoring a network, in particular a data or telecommunication network, where the network includes a number of units to be monitored, and where relevant states of these units are controlled with respect to functionality, efficiency and/or security by means of provided information elements called managed objects at the monitored units, that reflect states and/or parameters to be monitored, and that are read and/or written by a network management system using network management protocols, is characterized in that at the managed units an additional management object—the health check object—is being implemented, such that almost all relevant states of the respective monitored unit are aggregated into a single value, that can be read by the network management system.
