Future Directions for Differential Services (fddifs) ---------------------------------------------------- Charter Last Modified: 1997-03-24 Current Status: Concluded Working Group Chair(s): Brian Carpenter Transport Area Director(s): Scott Bradner Allison Mankin Transport Area Advisor: Scott Bradner Mailing Lists: General Discussion: To Subscribe: Archive: Description of Working Group: Goal: establish framework for future IETF work on differential service classes on IP networks. IntServ and RSVP describe an end-to-end session-based model for differential service classes. Doubts have been expressed about the scalability of this approach for the global Internet as well as doubts about how well these technologies match what Internet users would like to see as products from Internet service providers. Other models of differential service classes exist, with coarser granularity (per subscriber, per application class, etc.) These potentially rely only on simple mechanisms that implement the integrated services classes (local bandwidth management, precedence and TOS bits, WFQ, CBQ, etc.). The BOF will explore the types of differential services that are desired in the Internet and in private intranets and thus what directions IETF work should take in the area of differential services over IP, now that the basic IntServ & RSVP technologies are complete.
