متن کاملGuaranteed Frame Rate : a better service for TCP/IP in ATM networks
Guaranteed Frame Rate (GFR) recently approved by the ATM Forum is expected to become an important service category to efficiently support TCP/IP traffic in ATM networks. We first describe the GFR traffic contract in details. We then present different types of switch implementations that have been proposed to support GFR. We analyze the performance of three of these switch implementations by sim...

The Guaranteed Frame Rate service recently de ned by the ATM Forum allows users to send data in excess of their guaranteed service rate but only guarantees that such tra c will be delivered within the limits of available network resources that is it is transported on best e ort In order to distinguish tra c sent in line with the guaranteed service rate from tra c sent in excess a frame based ve...

Abstra t Di erentiated servi e approa h has been proposed as a potential solution to provide Quality of Servi es (QoS) in the next generation Internet. The ultimate goal of end-to-end servi e di erentiation an be a hieved by omplementing the network-level QoS with the servi e differentiation at the Internet servers. In this paper, we have presented a detailed study of the performan e of servi e...
متن کاملPerformance of the GFR-Service with Constant Available Bandwidth
Recently the ATM Forum defined the Guaranteed Frame Rate service category to provide a minimum service guarantee to classical best-effort services. The eligibility of frames for this service category is determined with the Frame Based Generic Cell Rate Algorithm and the transmission is guaranteed by a queuing-discipline based on two thresholds. In this paper we present a discrete-time analysis ...
