Dynamic Integrated Resource Management
QuO version 3.0 is now available
BBN Distributed Systems Project -- Technical Overview
The Dynamic Integrated Resource Management (DIRM) project will develop a high-level API that allows applications to control Quality of Service (QoS) for their communications over RSVP. This API will hide the complexity of the underlying RSVP control structures and present QoS abstractions in a form natural to application developers. Both a streams-based (socket) and object-based (CORBA) APIs will be developed. In order to implement this interface, information must be gathered and control coordinated among applications, network management, and network control systems.
Our approach is to combine several existing subsystems from different disciplines into a coherent system. The Quality Objects (QuO) architecture, from BBN, will be used to extend the CORBA interface to allow application to control and adapt to network performance. The QoS Management Environment (QoSME), from Columbia University, will similarly extend the streams/socket interface. An application management system will coordinate the use of network resources for group of users based on the MODEL event correlation system from SMARTS.
The toolkit created by this project will set a new high-water mark for integrating applications over emerging network functionality, such as resource reservation and multicast. The toolkit supports developers by offering a natural interface to QoS management. The toolkit supports operations by offering a comprehensive application management system that will allow QoS management over a group of end users. Using this toolkit will dramatically reduce the time to get military relevant applications to take advantage of new communication technologies.
