Establishing a multicast tree in a point-to-point network of switch nodes, such as a wide-area ATM network, can be modeled as the NP-complete Steiner problem in networks. In this paper, we introduce and evaluate two distributed algorithms for nding multicast trees in point-to-point data networks. These algorithms are based on the centralized Steiner(More)
<lb>In this paper, we propose and evaluate ARIES, a heuristic for updating multicast trees dynamically<lb>in large point-to-point networks. The algorithm is based on monitoring the accumulated damage to the<lb>multicast tree within local regions of the tree as nodes are added and deleted, and triggering a rearrangement<lb>when the number of changes within a(More)
We present a transport protocol that uses IP multicasting to provide reliable multicast transport services for distributed applications. The Transport Protocol for Reliable Multicast (TRM) has a receiver{ oriented style of deening group membership and the lack of group information at the source. The distributed nature of the group membership information(More)
BACKGROUND: A useful approach to quantifying factors which influence human performance involves the classification and comparison of so-called “elite” and “non-elite” performers. OBJECTIVE: In this pilot study, we classified 6 graduates of the Basic Underwater Demolition/SEAL training program as elite and compared them to 6 age-matched non-elite military(More)
We think that state-of-the-art techniques in computer graphics and geometry processing can be leveraged in training and entertainment to make the topic of cultural heritage more accessible to a wider audience. In a cooperation with the &#x201C;Antikensammlung&#x201D; in Erlangen we produced five unique applications - all based around emperor Augustus - to(More)
