Abstract: QoS (Quality of Service) guarantee is highly desirable for many
service-oriented computer and network applications on the Internet. This paper
focuses on the timeliness aspect of QoS, especially the end-to-end delay
guarantee. Resource reSerVation Protocol (RSVP) has been proposed based on the
Integrated Service (InteServ) model to provide the QoS guarantee through
bandwidth reservation that is applicable to jobs with continuous data flows
over a period of time, such as those for tele-conferencing, voice over IP,
video and audio streaming applications. There are other applications such as
emails generating one-time, instantaneous jobs that cannot be characterized by
the flow rate and peak rate for bandwidth reservation. Hence, RSVP is not
applicable to instantaneous jobs. This paper presents QoS protocols, called
Instantaneous RSVP (I-RSVP) and Stable Instantaneous Resource reSerVation
Protocol (SI-RSVP), which are developed for providing the end-to-end delay
guarantee of instantaneous jobs. The performance of I-RSVP and SI-RSVP are
tested and compared with that of the best effort service model using both small
and large scale network simulations.
