How does DMIF make use of the network standards?
The DMIF layer makes use of the available underlying network protocols to establish sessions and channels, as well as, to transfer the multimedia content for each of the channel of a session. The Control plane DAI primitives are mapped in underlying connection management mechanisms to establish and control the network resources needed in a DMIF session. On one hand, the Control plane DAI primitives are mapped into DNI messages, which can be subsequently mapped into existing network signaling protocols (e.g., UNI 4.0) and/or mapped into application-to-application signaling protocols (e.g., RTSP). In the absence of an application-to-application signaling protocol, DNI defines a syntax for a default signaling protocol (i.e., DS messages). On the other hand, the payload of the User plane DAI primitives (i.e., send and receive) are delivered using a multiplexing channel structure, called FlexMux, which is transported using any available and suitable transport stack (e.g., UDP/IP, AAL-5/ATM,
