Significant message precedence in object-based systems
Distributed applications are realized through cooperation among multiple objects. The state of an object depends on the order in which the objects exchange request and response messages. In this paper, we newly define an object-based precedent relation of messages based on a conflicting relation among requests. Here, only the messages to be ordered in the object-based system are ordered, and the others are not ordered. We discuss a protocol which supports object-based ordered delivery of request and response messages. Here, an object vector is newly proposed to order messages.
