RSSP: RSVP Session Set-Up Protocol for RSVP-Incapable Multimedia Applications

RSVP is the QoS signalling protocol used with Integrated Service Framework for QoS provisioning in IP networks. The existing RSVP mechanism requires that an RSVP daemon be embedded with the applications so as to initiate RSVP sessions. This requirement has been envisaged to be a major limitation over the use of RSVP and the associated QoS control mechanisms for those applications or platforms which are either RSVP-incapable or impossible to be modified to introduce a built-in RSVP capability. This paper introduces a mechanism, RSVP Session Set-up Protocol, which overcomes the limitations of existing RSVP implementations by initiating RSVP sessions for RSVP-incapable applications running on different platforms. The proposed mechanism features application and platform independence and eliminates the need for built-in RSVP processing capability for those applications or terminals of short battery life and limited processing power. Moreover it facilitates dynamic QoS provision for wireless mobile devices during hand-off control.
