【摘要】 <正> 1.引言异构网络互联的一个难点就是协议的不匹配,它导致不同网络体系下的用户难以直接相互通信。为了解决此困难,在协议间插入转换器当作通信中介,与协议实体一起形成网络系统,转换器依事先定义好的次序分发报文到另外一个协议实体,实现协议的转换。Okumura提出了采用单个通信有限状态机(CFSM)作为一个转换种子,用它来描述两个协议间的交互操作关系,该方法能自动构造一个转换器,但转换种子是依设计者给出,设计者应用不同的转换种子可能得出不同的转换器,在转换器不能构造时,不知是协议本身问题,还是更多还原

【Abstract】 A protocol converter can solve the problem of communication between heterogeneous and distributed computer networks. This paper proposes a novel approach to construct a converter for these protocols. This approach includes following steps: getting reduced protocol model by merging states and shielding insignificant message; constructing protocol converter by reduced protocols) dividing merged states and getting a protocol converter. This approach can improve computational complexity.更多还原
