Abstract: An interface unit providing an interface between a control and sensor system of an assisted vessel with thrust capabilities and a master dynamic positioning system. The master dynamic positioning system is configured to control a number of auxiliary vessels as one unit and control the thrust capabilities of the assisted vessel for assisting in maneuvering of the assisted vessel. A master dynamic positioning system comprises the interface unit above. A system for assisting in maneuvering of a vessel with thrust capabilities comprises the master dynamic positioning system controlling a number of auxiliary vessels as one unit for assisting in maneuvering of an assisted vessel. A dynamic positioning system of each of the auxiliary vessels is controlled by the master dynamic positioning system. The master dynamic positioning system controls the thrust capabilities of the assisted vessel. The master dynamic positioning system may be provided on-board a tugboat.

Abstract: A method for measuring the performance of a large computer network is defined. The method provides a method of defining and characterizing the population of interest and interesting sub-populations; a method of providing a sampling list of nodes that represent the population; measuring the performance of destinations in the sampling list; recording raw data therefrom; reducing the raw data and providing presentations of information indicative of one or more of the sub-populations in ways that address questions of interest.

Abstract: A method for monitoring of network performance is defined. The method includes the steps of defining and characterizing the population of interest (the set of hosts and networks in which there is interest); choosing a set of destinations that represent the population (pinglists) including categorization structure (viewlists); monitoring the destinations in the pinglists from one or more vantage points (beacons) and collecting information therefrom; compiling and summarizing the data in ways that address questions of interest about the population; and providing an appropriate interpretation of the analysis in terms of the questions of interest.
