Abstract
In ATM networks, the guaranteed frame rate (GFR) service has been designed to accommodate non-real-time applications, such as TCP/IP-based traffic. The GFR service not only guarantees a minimum throughput at the frame level, but also supports a fair share of available resources. In this article, we propose a buffering strategy called intelligent fair buffer allocation (IFBA) that provides MCR (minimum cell rate) guarantees and fair sharing to GFR VC (virtual circuits). From the simulation results, we demonstrate that IFBA fulfils the requirements of GFR service as well as improves the TCP throughput using FIFO scheduling.
