Vadim, My understanding is that RSVP is targeted to solve the problem of offering services such as audio/video conferencing, audio/video streaming such as radio/television, and telephony services on the Internet and private networks that use IP. A "problem to start with" is offering these services in the current Internet does not yet work. Cheers, peter
