Abstract :
We investigate the TCP packet transmission over the ATM guaranteed frame rate (GFR) service using the proposed virtual buffering strategy (VBS) which provides both minimum cell rate (MCR) guarantees and fair sharing to GFR VCs on a FIFO queue. VBS is composed of an emulation of per-VC queueing with weighted round robin (EWRR) and the differential packet discarding (DPD) buffer management scheme. From the simulation results, we demonstrate that VBS fulfils the requirements of GFR service as well as improves the TCP throughput
