针对大规模分布式系统中对象迁移、网络和系统动态重构的要求,文中介绍了一种层次式的命名和编址方案,它将对位置透明的标识(OID)和表示位置的地址(OAD)二者结合起来标识对象.从局部唯一的ID和地址出发构造全局ID和地址,它们是相对表示,当在命名上下文中传送时被转换,从而保证了ID的唯一性,也缩短了对象标识符的大小.尤其在网络和系统动态重构时,其优点更为突出,用户无需了解对象地址的改变就可进行正确通信,实现了位置透明性.文中还就命名方案的实现问题进行了探讨
In order to meet the requirements of object migration, network and system dynamic reconfiguration in large-scale distributed systems, a layered naming and addressing scheme is introduced in this paper. The transparent OID and location-oriented address (OAD) ) The two combine to identify the object. Starting from a locally unique ID and address, global IDs and addresses are constructed, which are relative representations that are translated when passed in naming contexts, thereby ensuring the uniqueness of IDs and the size of object identifiers. Especially in the network and system dynamic reconfiguration, the advantages are more prominent, users do not need to understand the change of object address can be the correct communication, to achieve the position of transparency. The paper also discusses the realization of the naming scheme
