Abstract: Distributed object management is important in implementing distributed object interoperability. This paper presents an expanded and improved basic trading model of ODP to implement the local management of object services. Based on the new trading model, it proposes a federated trading model in large-scale distributed object interoperability environments, which provides new concepts of trading space and confidence. It describes the rigorous federated search procedure and search rules and the algorithm for the best federated search route, and also provides the structure model of federated trading and the federated consultation protocol to establish federated trading.

Key words: basic trading model, federated trading model, trading space, confidence, federated search route

摘要： 分布对象管理是实现分布对象互操作的一个重点。该文通过扩展ODP中的基本交易模型，实现了对象服务的局部管理，提出了一种新的联邦交易模型，使用联邦交易空间和信任度的概念实现了大规模互操作环境中的对象服务的全局管理，给出了分布对象服务的联邦搜索过程和联邦搜索规则，以及联邦查询的最佳搜索路径选择算法，研究并提出了联邦交易的实现结构模型和建立联邦和约的协商协议。
