ROIA: The Architecture and State Consistency

Real-time online interactive application (ROIA) is an emerging distributed application in recent years. Compared with other general distributed applications, ROIA has its own challenging features. In this paper, we focus on the architecture and state consistency of ROIA. First, the paper classifies the architectures of ROIA in detail and compares their merits and disadvantages. Then, the paper discusses the key issue of ROIA: the state consistency. The paper analyzes the two basic consistency models, and describes the consistency maintenance in C/MS model.
