YES. RTP contains no specific assumptions about the capabilities of the lower layers, except that they provide framing. It contains no network-layer addresses, so that RTP is not affected by ADDRESSING changes. Any additional lower-layer capabilities such as SECURITY or quality-of-service guarantees can obviously be used by applications employing RTP. There are several implementations of video tools that run RTP directly over AAL5 (T. BRAUN) and recent efforts to define the carriage of RTP over AAL2 and AAL5. It should be noted that the RTCP CNAME field is currently based on the assumption that hosts have Internet-style domain names.
