分布式机构系统的设计、实现与应用

A System for Distributed Mechanisms: Design, Implementation and Applications

Krzysztof R. Apt, Farhad Arbab, Huiye Ma

摘要:

我们在这里描述了一个适用于内联网和互联网应用程序的分布式机制设计的结构化系统。在我们的方法中,玩家动态地形成一个网络,在这个网络中,他们既不知道他们的邻居,也不知道网络的大小,他们相互作用,共同做出决定。关于底层通信层的唯一假设是,对于每对进程,都有一条相邻进程的路径将它们连接起来。这允许我们处理任意的网络拓扑。我们还讨论了该系统的实现,其中包括一个序列的层。较低层处理实现分布式计算的基本原语的操作,即低层通信和分布式终止,而上层使用这些原语来实现参与者之间的高层通信,包括广播和多播以及分布式决策。这就产生了一个高度灵活的分布式系统,其特定的应用程序作为其顶层的实例来实现。这个设计是用Java实现的。该系统在各级支持容错,并包括一项分散监管的规定,其目的是排除“不诚实”的参与者。此外,它可以用于重复创建动态形成的参与者网络,这些参与者对通过基于税收的机制实现的联合决策感兴趣。我们说明了它的灵活性,通过讨论一些实施的例子。

英文摘要:

We describe here a structured system for distributed mechanism design appropriate for both Intranet and Internet applications. In our approach the players dynamically form a network in which they know neither their neighbours nor the size of the network and interact to jointly take decisions. The only assumption concerning the underlying communication layer is that for each pair of processes there is a path of neighbours connecting them. This allows us to deal with arbitrary network topologies. We also discuss the implementation of this system which consists of a sequence of layers. The lower layers deal with the operations that implement the basic primitives of distributed computing, namely low level communication and distributed termination, while the upper layers use these primitives to implement high level communication among players, including broadcasting and multicasting, and distributed decision making. This yields a highly flexible distributed system whose specific applications are realized as instances of its top layer. This design is implemented in Java. The system supports at various levels fault-tolerance and includes a provision for distributed policing the purpose of which is to exclude `dishonest' players. Also, it can be used for repeated creation of dynamically formed networks of players interested in a joint decision making implemented by means of a tax-based mechanism. We illustrate its flexibility by discussing a number of implemented examples.
