Description of Working Group:
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.
