Improving on service-customizing for applications in PGPS-based IntServ/RSVP architecture

The future Internet is expected to support applications with quality of service (QoS) requirements. For this end several mechanisms are suggested in the IETF to support signaling, one of the most promising component among them is IntServ. In this paper, we study the relationship between the QoS implementing mechanism and application demands, and make a set of an improved application interface beyond the standard resource reservation protocol (RSVP) application programming interface (API). Our goal is to provide an API friendly to applications, through extracting the key elements from the traffic parameters and reservation parameters which should be opaque to applications.
