在全球系统中定位移动的对象需要可扩展的定位服务。对象可以是电话或笔记本电脑，也可以是软件或数据对象，例如文件或电子文档。我们的服务严格区分对象的名称和可以联系的地址。这是通过引入位置无关的对象句柄来实现的。对象的名称绑定到其唯一的对象句柄，而对象句柄又映射到可以联系该对象的地址。要定位一个对象，我们只需要它的对象句柄。我们提出了一个可扩展的位置服务的基础上，全球分布式搜索树，动态适应对象的迁移模式，以优化查找和更新。
Locating mobile objects in a worldwide system requires a scalable location service. An object can be a telephone or a notebook computer, but also a software or data object, such as a file or an electronic document. Our service strictly separates an object's name from the addresses where it can be contacted. This is done by introducing a location-independent object handle. An object's name is bound to its unique object handle, which, in turn, is mapped to the addresses where the object can be contacted. To locate an object, we need only its object handle. We present a scalable location service based on a worldwide distributed search tree that adapts dynamically to an object's migration pattern to optimize lookups and updates.
