Multi-Protocol Architecture as a Paradigm for Achieving Inter-Operability

9305115 Ammar实现异构系统互连的一个重要障碍是需要在所有通信系统上保持兼容的网络协议。协议标准化和分析一直被视为克服这一障碍的一种方法。然而，这种方法的排他性存在一定的局限性。其中包括排除有时较先进的技术，以及系统之间必须严格一致。本研究将考虑一种基于使用多协议架构实现互操作性的包容性方法，即混合了来自不同标准家族的协议的系统。这些体系结构中的互操作性是通过以下方式实现的：1)在系统实现的协议中提供足够的重叠；2)为系统提供可用于确定这种重叠的机制。这项工作将有两个主要组成部分：一个模型建立活动，它将有助于集中工作，并有助于确定问题和解决方案；另一个并行的实施活动基于对因特网和OSI协议套件的案例研究。＊＊＊

9305115 Ammar A significant obstacle to achieving heterogeneous system interconnection is the need to maintain compatible network protocols on all communication systems. Protocol standardization and profiling has long been viewed as a way to overcome this obstacle. The exclusive nature of this approach, however, presents certain limitations. Among them are exclusion of sometimes superior technology and the necessity for strict agreement among systems. This research will consider an inclusive approach for achieving inter-operability based on the use of multi-protocol architectures, that is systems with a mixture of protocols from different standards families. Inter-operability in these architectures is achieved by 1) providing sufficient overlap in the protocols that systems implement and 2) equipment systems with the mechanisms that can be used to determine this overlap. The work will have two major components: a model building activity which will help focus the work and help in identifying problems and solutions and a parallel implementation activity based on a case study of Internet and OSI protocol suites. ***
