Effects of Variations in the Available Bandwidth on the Performance of the GFR Service
Norbert Vicari · 2000
The Guaranteed Frame Rate service category is currently under discussion for incorporation into the specification documents of the ATM-Forum. The concept of the GFR service is to provide a minimum service guarantee to classical best-effort services, taking into account the frame-based nature of todays data-traffic. In this paper we present a discrete-time analysis of the GFR service and discuss the effects of variations of the bandwidth available for the GFR service. The presented method can be applied to dimension the thresholds of the algorithms used to enforce the guaranteed service.
