The applications that will be implemented on future high-bandwidth networks of processors will be significantly more ambitious than the current applications (which are mostly involved with transmissions of digital data and images). This project attempts to develop an object-based model of concurrent programming for these applications, that permits the programmer to employ a largely sequential style of programming for concurrent threads. Concepts developed for databases, object-based programming and reactive systems form the basis of this model. The model is minimal: no specific communication or synchronization mechanism, except procedure call, is built into this model. The traditional schemes for communication, synchronization, interfaces among processes and accesses to shared memory are encoded by objects. Concurrency is transparent to the programmer; the programmer believes that the program executes in a sequential manner whereas the implementation employs concurrent threads to gain efficiency. The project plan is to solidify the theoretical foundation of the work, and extend the basis of the model to make it more useful in practice, introducing real time, dynamic object creation, more general forms of parameter passing among object instances, and recursive calls among concurrent threads.

在未来的高带宽处理器网络上实现的应用程序将比当前的应用程序（主要涉及数字数据和图像的传输）更加雄心勃勃。这个项目试图为这些应用程序开发一个基于对象的并发编程模型，它允许程序员为并发线程采用一种主要的顺序编程风格。 为数据库开发的概念，基于对象的编程和反应式系统形成了这个模型的基础。 该模型是最小的：没有特定的通信或同步机制，除了过程调用，内置到这个模型。传统的通信、同步、进程间接口和访问共享内存的方案都是用对象编码的。 并发性对程序员来说是透明的;程序员相信程序以顺序方式执行，而实现则使用并发线程来提高效率。 项目计划是巩固工作的理论基础，并扩展模型的基础，使其在实践中更有用，引入真实的时间，动态对象创建，对象实例之间的参数传递的更一般的形式，并发线程之间的递归调用。
