ACE (the ADAPTIVE Communication Environment) is an Object-Oriented (OO) Network Programming Toolkit for C++.

ACE provides a rich set of reusable C++ wrapper facades and framework components that perform common communication software tasks across a range of OS platforms. The communication software tasks provided by ACE include:

  • Event De-multiplexing and Event Handler Dispatching,
  • Signal Handling,
  • Service Initialization,
  • Inter-process Communication,
  • Shared Memory Management,
  • Message Routing,
  • Dynamic (Re)Configuration of Distributed Services,
  • Concurrent Execution and Synchronization.

The Benefits of Using ACE

  • Increased portability. ACE components make it easy to write concurrent networked applications on one OS platform and quickly port them to many other OS platforms. Moreover, because ACE is free and open source software (FOSS), operating system or compiler lock-in is not a concern.
  • Increased software quality. ACE components are designed using many key patterns that increase key qualities, such as flexibility, extensibility, reusability, and modularity.
  • Increased efficiency and predictability. ACE is carefully designed to support a wide range of application quality of service (QoS) requirements, including low latency for delay-sensitive applications, high performance for bandwidth-intensive applications, and predictability for real-time applications.
  • Easier transition to standard higher-level middleware. ACE provides the reusable components and patterns used in The ACE ORB (TAO), which is an open-source standard-compliant implementation of CORBA that's optimized for high-performance and real-time systems. Thus, ACE and TAO are designed to work well together in order to provide comprehensive middleware solutions.
