Networked Group Communication - Techniques for Making IP Multicast Simple and Scalable
Lecture Notes in Computer Science, 1999Co-Authors: Radia J. Perlman, Suchitra RamanAbstract:This paper describes Root Administered Multicast Addressing (RAMA), a protocol for wide-area IP multicast that scales to a large number of simultaneous Groups with topologically distant members. RAMA solves the wide-area “rendezvous” problem by making the root of the distribution tree explicit in the multicast Group Identifier. This is done by extending the 4-byte IPv4 multicast Group address format to an 8-byte address format, (R, G), where R is the unicast address of the root of the multicast distribution tree and G is a Group Identifier, unique with respect to R and administered by it. Data distribution occurs via a single shared bi-directional tree, allowing scalable operation for multiple senders. RAMA generalizes two recent protocols, Simple Multicast [18] and EXPRESS Multicast [10], into a common protocol that has the desirable features of both.

system method and apparatus for Grouping building automation objects for Group communication within a building automation system
2013Co-Authors: James J Coogan, William H Choi, Gerhard BrunAbstract:A system is provided for communicating common data associated with building automation objects between building automation devices across a network. The common data corresponds to a Group of one or more building automation objects representing points associated with a plurality of field devices controlled or monitored in a building by the building automation devices. The system comprises a first building automation device having a Group master object that includes a Group Identifier. A second building automation device includes a Group member object having the same Group Identifier as the Group master object. The Group master object exchanges the common data to each of the building automation devices having a Group member object that has the same Group Identifier as the Group master object.

CSCWD - An event and service interacting model and event detection based on the broker/service model
Proceedings of the Sixth International Conference on Computer Supported Cooperative Work in Design (IEEE Cat. No.01EX472), 1Co-Authors: Ping-peng Yuan, Gang Chen, Jinxiang Dong, Wei-li HanAbstract:In distributed systems based on B/SM, events and event-condition-action rules are the fundamental metaphors for defining and enforcing the system. Processing entities execute behavior by reacting to and generating new events. It is important that event semantics is explicit. Although a lot of research has concentrated on event semantics, there still exists potential semantic ambiguity which is unacceptable in some circumstances. We propose an event model and incorporate an interaction Group Identifier into it. We emphasize that the semantics is a key to capture the actual meaning of events in real life, in which the same composite event patterns may imply totally different semantic meanings. Based on this observation, a graph-ESIG (Event and Service Interacting Graph) and ESIC (Event and Service Interacting Chain), which are constructed according to ECA-Rules, are proposed to trace events. ESIG greatly enhanced the expressive power to allow event detection correctly, which matches situations in reality. Finally, we develop a event detection algorithm that uses ESIG and ESIC.

The Experimental Economics of Religion
2011Co-Authors: Robert HoffmannAbstract:This article surveys the experimental economics approach to the study of religion. The field has a place in the context of the scientific study of religion generally and the social psychology of religion in particular, but employs distinct economic methods which promise new and different insights. In particular, certain features of the experimental approach as used by economists such as incentive compatibility are particularly appropriate for studying the effect of religion on individual behaviour. The paper discusses results obtained so far in terms of two roles of religion in shaping individual behaviour, i.e. as a social Group Identifier and as a set of values.
