Autonomous decentralized system with event service for information services

Autonomous Decentralized System (ADS) has the properties of online expansion, online maintenance and fault tolerance, which are among the important features for next generation information services. Since information services require transfer of large amounts of data with different levels of Quality of Services (QoS), it is necessary, to have an ADS architecture to satisfy these requirements. This approach uses event service as the communication middleware and ATM network to handle large amounts of data and satisfy various QoS requirements.
