Abstract: An arrangement for handling control signal messaging in a distributed system comprising a number of sending nodes and a number of receiving nodes and implementing a control signaling communication protocol. The sending and/or the receiving node is adapted to send and/or receive the current message as a compressed message comprising only the difference portion between a selected or preferred previous message and the current message and the unique identity of said previous message.

Abstract: A software performance-analysis and installation method includes estimating performance of a system including a software component to be installed on the system and determining, based on the estimated performance, whether to install the software component in a current configuration. The software component is installed in the current configuration responsive to a determination to install the software component in the current configuration. At least one of the following four steps is performed responsive to a determination not to install the software components to be installed in the current configuration: (1) deleting at least one software component of the system; (2) determining a new usage profile; (3) aborting installation of the software component to be installed; and (4) selecting an alternative component to be installed. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure.
