A CORBA based architecture for QoS-sensitive networking

We describe an architecture, based on the common object request broker architecture (CORBA), for the communication support of quality of service (QoS) sensitive networked multimedia applications. Shared by both control and management entities, this architecture smoothly integrates real-time QoS oriented communication services, such as those offered now or planned for the future in the public network, with everyday services of the Internet. A prototype system is presented which features virtual interfaces that pass QoS information in both directions between a network and an end system, a domain resources manager for maintaining network control policies, and a streams architecture, as an example of a virtual service that facilitates rapid service deployment.
