Implementing Flexible Object Group Invocation in Networked Systems

Distributed applications should be able to make use of an object group service in a number of application specific ways. Three main modes of interactions can be identified: (i) request-reply: a client issues a request to multiple servers and waits for their replies; this represents a commonly occurring scenario when a service is replicated; (ii) group-to-group request-reply: a generalisation of the previous case, where clients are themselves groups; and (iii) Peer Participation: here all the members are regularly multicasting messages (asynchronous invocation); this represents a commonly occurring scenario when the purpose of an application is to share information between members, (e.g., a teleconferencing application). Customisation within each class of interaction is frequently required for obtaining better performance. This paper describes the design and implementation of a flexible CORBA object group service that supports the three types of interactions and enables application spe...
