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

9305115 Ammar实现异类系统互连的一个重大障碍是需要在所有通信系统上保持兼容的网络协议。长期以来，协议标准化和概要分析一直被视为克服这一障碍的一种方法。然而，这种方法的排他性带来了一定的局限性。其中包括排除有时更先进的技术，以及有必要在系统之间严格达成一致。这项研究将考虑一种基于使用多协议体系结构实现互操作性的包容性方法，即具有来自不同标准家族的混合协议的系统。这些体系结构中的互操作性通过1)在系统实现的协议中提供足够的重叠，以及2)装备具有可用于确定这种重叠的机制的系统来实现。这项工作将包括两个主要部分：一个是建立模型活动，它将有助于集中工作并帮助确定问题和解决办法；另一个是以因特网和开放系统互连协议组的案例研究为基础的并行执行活动。***

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. ***
