ACE自适配通信环境（ADAPTIVE Communication Environment）是可自由使用、开放源码的面向对象（OO）构架（fr a mework），它实现了许多用于并发通信软件的核心模式。ACE提供了一组丰富的可重用C++包装外观（wrapper facade）和构架组件，可跨多种平台完成通用的通信软件任务，其中包括：事件多路分离和事件处理器分派、信号处理、服务初始化、进程间通信、共享内存管理、消息路由、分布式服务动态（重）配置、并发执行和同步，等等。 -ACE ADAPTIVE Communication Environment (ADAPTIVE Communication Environment) is free to use, open source object-oriented (OO) architecture (fr a mework), which implements many core patterns for concurrent communication software. ACE provides a rich set of a reusable C++ packaging appearance (wrapper facade) and fr a mework components that perform common communication software tasks across a variety of platforms, including: event demultiplexing and event handler dispatching, signal processing, service initialization, interprocess communication, shared memory management, message routing, distributed services dynamic (re) configuration, concurrent execution and synchronization, and so on.
