Group protocol for inter-object communications
Y. Timura, Katsuya Tanaka, Makoto Takizawa · 2002
Distributed applications are realized by cooperation of a group of multiple objects. In the group cooperation, objects send and receive messages in various ways. A message is multicast to objects in the group. In addition, multiple types of messages are in parallel sent to multiple destinations. Then, an object waits for messages from all and some of the source objects. i.e. conjunctive and disjunctive ways. In this paper, we newly define a novel precedent relation on request and response messages exchanged among objects in presence of the transmission and receipt ways. We present a protocol for supporting the ordered delivery of messages in the precedent relation.
