cost nowadays reaches 80% of the IT expenditure. coordination even under any subsystem’s in-operation.

The ADS take a bottom-up approach, which means that at first each subsystem exists and then the system is clarified

as the results of the integration of the subsystems.

The ADS have been motivated from two aspects of the technologies advancements such as the LSI and optical fiber, and of the evolving market requirements of the on-line property. Therefore until now, the ADS technologies have been advanced in the local-area network-oriented manufacturing, railway transportation, utility management, car/satellite on-board computing, systems and so on. While, the Internet is itself the integration of the autonomous communication subsystems (nodes) and it has been gradually expanded from the local to the global.

3. Conclusion

The ADS have been expected for the system assurance, the efficient investment of the IT systems and the customer-oriented services, and the autonomous community technology is one of the new paradigms.
