RSVP is a resource reservation setup protocol for the Internet. Its major features include: (1) the use of ``soft state'' in the routers, (2) receiver-controlled reservation requests, (3) flexible control over sharing of reservations and forwarding of subflows, and (4) the use of IP multicast for data distribution. The primary purpose of this working group is to evolve the RSVP specification and to introduce it into the Internet standards track. The working group will also serve as a meeting place and forum for those developing and experimenting with RSVP implementations. The task of the RSVP Working Group, creating a robust specification for real-world implementations of RSVP, will require liaison with two other efforts: (1) continuing research and development work on RSVP in the DARTnet research community, and (2) the parallel IETF working group that is considering the service model for integrated service. Although RSVP is largely independent of the service model, its design does depend upon the overall integrated service architecture and the requirements of real-time applications. As an additional task, RSVP will maintain coordination with the IPng-related working groups.
