Abstract

Whe origin of the RSVP protocol can be traced back to 1991, when a team of network researchers, including myself, started playing with a number of packet scheduling algorithms on the DARTNET (DARPA Testbed NETwork), a network testbed made of open source, workstation-based routers. Because scheduling algorithms simply shuffle packet processing orders according to some established rates or priorities for different data flows, to test a scheduling algorithm requires setting up the appropriate control state at each router along the data flow paths. I was challenged to design a set-up protocol that could support both unicast and many-to-many multicast applications. That effort led to the birth of RSVP. As a signaling protocol designed specifically to run over IP, RSVP distinguishes itself from previous signaling protocols in several fundamental ways. The most profound ones include a soft-state approach, two-way signaling message exchanges, receiver-based resource reservation, and being independent from all other related components in a QOS support architecture, such as flow-specification, admission control, scheduling algorithm, and routing. As stated in the article, “RSVP is primarily a vehicle used by applications to communicate their requirements to the network in a robust and efficient way, independent of the specific requirements.” It has been more than 10 years since the original idea
