Does Internet make DSM-CC redundant with RSVP, RTSP, RTP and SCP?
No, DSM-CC is not made redundant. DSM-CC works in conjunction with these protocols. There are two main components of DSM-CC, U-N and U-U. Equivalence can be drawn between U-N and RSVP on the one hand and U-U and RTSP, RTP and SCP on the other hand. RSVP is not able to account for the stacks above which IP packets are carried. DSM-CC U-N on the other hand accounts for the layers of transport above which IP packets are carried as network connection resources. In addition DSM-CC can account for network processing resources which are used, such as multicast servers and translators. Since DSM-CC U-N can be implemented independently from DSM-CC U-U it can operate with RTSP, RTP and SCP. RTSP provides the equivalent of the DSM-CC U-U directory resolve and stream control while RTP and SCP provide the equivalent of MPEG-2 TS and allows for the selection of a transport within the confines of connections between the sender and the receiver (or receivers for multicast). In comparison DSM-CC U-U al
