The classical resource reservation protocol (RSVP) is a flow-based signaling protocol used for reserving resources in the network for a given session. RSVP maintains state information for each reservation at every router along the path. Even though this protocol is very popular, he has some weaknesses. Indeed, RSVP does not include a bidirectional reservation process and it requires refresh messages to maintain the soft states in the routers for each session. In this paper, we propose a senderoriented version of RSVP that can reserve the resources in both directions with only one message, thus reducing the delay for establishing the reservations. We also suggest a refreshment mechanism without any refresh message which could be applied to any soft states protocol. Simulation results show that the proposed protocol is approximately twice faster than RSVPv2 for establishing bidirectional reservations with almost no control overhead during the session.
