In this community, an adaptive system is a system where the implementation of the system software can change even while the system is used.
This kind of adaptiveness is very useful when the behavior of the system cannot be analyzed statically such as data dependent behavior.
For the software engineering adaptiveness this is possible by using the evolutionary meta-object protocol of Huersch described in his thesis.

 Introduction
In particular, advances in IP-based communication for handheld devices equipped with wireless interfaces is creating new challenges for mobile middleware frameworks, while opening new possibilities in areas such as distributed robotic system (DRS), where intelligent autonomous mobile robots can communicate and collaborate in order to perform complex tasks.
To provide an adaptive communication environment that will make it transparent to the application and robot what the actual network characteristics are and how to deal with the inherent restrictions.
Communication Environment: At the application level, the impact of mobility in communication intensive tasks, such as video processing in wireless devices, should be hidden by enforcing communication policies that allow the robot to adapt in response to an environmental or system configuration change.

 Adaptive Middleware for Disrtibuted Mobile Robotic Systems
Furthermore, the specification and enforcement of QoS present interesting challenges in mobile environments, due to their lack of support for continuous flow of information over error-prone channels and the notion of an on-going communication activity with an associated QoS.
It provides a comprehensive set of basic communication services and an appropriate transfer system offering transparency of the underlying heterogeneous UMTS network to support basic communication and common application services [M16].
By dynamic customization we mean adding and possibly removing communication services on the fly in a plug-n-play manner, in order to respond to new requirements demanded by the environment.

The Adaptive Communication Environment (often referred to as ACE) is an open source framework of object oriented classes to help the developing of communication software.
ACE is one of many solutions to a common problem: making easy to use powerful but complex features of modern operating systems like inter-process communication, thread management, efficient memory management and so on.
ACE is written in C++ and runs on a wide variety of operating systems (most Unixes, Microsoft Windows various versions, real-time systems like VxWorks and QnX).

 Parallel Protocol Processing   (Site not responding. Last check: 2007-11-02)
The demand for high-performance distributed communication systems (such as video-on-demand servers, global personal communication systems, and the underlying communication protocol stacks) is increasing dramatically.
Many communication systems (such as the standard layered protocol stacks specified by the TCP/IP and the ISO OSI reference models) decompose naturally into a series of hierarchically-related tasks.
This knowledge has led to the development and deployment of distributed communication systems that effectively utilize parallelism to satisfy their performance requirements.

Object-oriented analysis and design, C++, and design patterns are helping more and more of today's harried engineering teams put their expertise into domain-specific engineering problems, without needing to solve many of the same framework issues over and over on each new project.
The ADAPTIVE Communication Environment (ACE) is a modern, high-performance framework and C++ class library that provides precisely these benefits, providing a wide variety of classes and patterns, allowing your engineers to concentrate on adding the domain-specific knowledge, and complete your projects in shorter times.
And, since ACE provides the framework and patterns commonly found in high-performance, networked, multi-threaded systems, there is much less code for your team to write (and debug), reducing both your engineering and maintenance costs, now and in the future.

 Developing Efficient Network and Distributed Applications with ACE, Part 2
Communication in a distributed application that implements ACE follows the usual client/server model (refined into a new Acceptor-Connector pattern by ACE).
It involves an active client that initiates a communication and requests for a connection for data exchange; and a passive server that waits for a needy client to initiate communication and request for a connection to arrive.
Note: ACE allows the reversal of client and server roles anytime during communication, once a connection between the two is established.

For platforms that support shared memory, communication overhead can be minimized by storing the current time into shared memory that is mapped into the address space of the Clerk and all Clients on the same host.
In contrast, in a real-time avionics environment it might be necessary to co-locate the Clerk and the Time Server into one process to reduce communication latency.
