Future Standards Development

With the revision of RTP for draft standard status, there are no known unresolved issues with the protocol specification, and RTP itself is not expected to change in the foreseeable future. This does not mean that the standards work is finished, though. New payload formats are always under development, and work on new profiles will extend RTP to encompass new functionality (for example, the profiles for secure RTP and enhanced feedback).

In the long term , we expect the RTP framework to evolve along with the network itself. Future changes in the network may also affect RTP, and we expect new profiles to be developed to take advantage of any changes. We also expect a continual series of new payload format specifications, to keep up with changes in codec technology and to provide new error resilience schemes.

Finally, we can expect considerable changes in the related protocols for call setup and control, resource reservation, and quality of service. These protocols are newer than RTP, and they are currently undergoing rapid development, implying that changes here will likely be more substantial than changes to RTP, its profile, and payload formats.
