PETRI NET-BASED ANALYSIS ON OBJECT ASSIGNMENT IN DISTRIBUTED OBJECT-ORIENTED SYSTEMS

Object-oriented programming [9], which treats objects as processes in execution, has shown significant effectiveness in distributed systems. This effectiveness is greatly influenced by how objects are assigned to nodes. In this paper, we present a colored generalized stochastic P etri net (CGSPN) model to analyze the behavior of object invocations w hen an assignment strategy is applied. The effectiveness of an object assignment is also analyzed by our CGSPN model. Moreover, this analysi s provides guidelines to develop an efficient object assignment strate gy. [4-8].
