An Implementation Model of IntServMVP based CORBA AN Stream Service
Junqing Xie, WangYun Gu Guanqun · 2000
In order to meet the requirements of building CORBA-based distributed multimedia applications, OMG has defined the CORBA AN Stream Service Specification. However, it is not specified to use what network mechanism to ensure the QoS of multimedia streams. In this paper, an implementation model of IntServ/RSVP based CORBA AN Stream Service is proposed. It first maps the application-level QoS parameters of multimedia streams specified by application developers into network-level QoS parameters. It then negotiates the QoS requirements with the IntServ/RSVP enabled network and reserves corresponding network resource in the endsystems and intermediate network systems to maintain end-to-end QoS enforcement through the RSVP API. Also, developers can flexibly control and manage the multimedia streams using CORBA IIOP protocol.
