摘要： An improved method and apparatus for dynamic execution of mobile agents. For example, a symbolic name for a component to be executed can be dynamically resolved using a component directory to determine an appropriate network host that the agent needs to visit. Preferably, the component directory can be queried by client or host machines, and updated by component hosts. Changes in a component's location and/or availability can also be captured at runtime and the agents dynamically routed to alternate component hosts. Still other features enable agents to flexibly accommodate the dynamics of the system. For example, if the attributes of a component are modified, or a component host becomes heavily loaded, agents can adapt to such changes by looking up an alternate host for the same component. Yet other features provide improved system manageability. For example, component hosts can freely update a component's location and/or attributes at any time. Changes to code for agents that use components residing at an updated component location are not required.
摘要翻译：一种用于动态执行移动代理的改进方法和装置。例如，可以使用组件目录来动态地解析要执行的组件的符号名称，以确定代理需要访问的适当的网络主机。优选地，组件目录可以由客户机或主机查询，并由组件主机更新。还可以在运行时捕获组件位置和/或可用性的更改，并将代理程序动态路由到备用组件主机。还有其他功能使代理能够灵活地适应系统的动态。例如，如果组件的属性被修改或组件主机变得负载过重，则代理可以通过查找相同组件的备用主机来适应这些更改。其他功能提供了改进的系统可管理性。例如，组件主机可以随时自由地更新组件的位置和/或属性。不需要对使用位于更新组件位置的组件的代理程序的代码进行更改。

摘要： A system and method wherein a mobile user, or a user interacting with a mobile program, can at any time initiate a program status request. The program status request initiates the sequence of events whereby the current location of the program is determined and/or the current user location is made available to the program without the necessity of either entity changing location. Further, the agent script for the program maintains a composite data structure which includes an input buffer for storing input variables, an output buffer for storing output values to be displayed to the user, a program state data structure, and an optional bag buffer for temporarily storing input variables which the program will need in the course of future execution. By maintaining such a composite data structure, it is assured that all necessary information can be provided at a program location regardless of whether the program or the user has relocated.

摘要： A general purpose mechanism is provided for consolidating the launching of multiple tasks, wherein a task is launched when an associated software component is run or executed. In one embodiment, launch descriptions of individual tasks and composition parameters are respectively read, wherein the parameters indicate relationships between the launchings of different tasks, such as launch order. A composite launch description is constructed, by selectively processing the individual launch descriptions and composition parameters, and the tasks are launched according to the composite launch description. In a further embodiment, multiple individual launch descriptions are delivered to a tool, each launch description being usable to launch a corresponding component to perform a corresponding task. The tool includes a set of launch relationships that specify the relationship between launchings of different components. The tool generates a single composite launch description that defines launching of the components in accordance with the launch relationships.

摘要： A framework of a service directory that can handle service records changing rapidly is provided by using a content-based routing network. A directory node for providing the service directory is called a data resolver. The data resolver listens for service advertisements for certain service categories from service providers, and stores such advertisement data in the form of service records in a local cache. If a data resolver receives a query for some services, it first looks in the cache. If the cache contains at least one service record that satisfies the query, the data resolver returns the record. Otherwise, the data resolver issues a secondary query corresponding to the query it received, to other data resolvers connected by the content-based routing network. Simultaneously, the data resolver begins listening for service advertisements (service records) from other data resolvers on the content-based routing network.

摘要： The present invention discloses a new synchronization architecture for synchronization of data between different clients by using a central synchronization server linked to a Back End data store which additionally provides a cache for permanently buffering incoming updates into a permanent store by assigning an unique cache identifier (ID). Write conflicts between the synchronization server writing new entries to the cache and updates replicated from backend to cache are solved using a blocking mechanism based on the cache IDs, so that the backend updates are blocked as long as incoming updates from the clients having the same cache ID are not completely written into the cache during a synchronization session. The present invention is preferably suited for a synchronization architecture having a high number of clients connected with the central synchronization server as blocking of the Back End data store, and the connection and the transport to the Back End data store are minimized.
摘要翻译：本发明公开了一种用于通过使用链接到后端数据存储器的中央同步服务器在不同客户端之间进行数据同步的新同步架构，其另外提供用于通过分配唯一高速缓存标识符（ID）来永久地将进入的更新缓存到永久存储器中的高速缓存）。使用基于缓存ID的阻止机制来解决将写入缓存的新条目的同步服务器与从后端复制到高速缓存之间的写入冲突，只要来自具有相同缓存的客户端的传入更新就会阻止后端更新 ID在同步会话期间未完全写入高速缓存。本发明优选地适合于具有与中心同步服务器连接的大量客户端作为后端数据存储器的阻塞的同步架构，并且连接和到后端数据存储器的传输被最小化。
