A high-speed novel fair buffer allocation for ATM-GFR services in TCP/IP internetworks

Within an ATM network domain, the guaranteed frame rate (GFR) service has been designed to accommodate non-real-time application, such as TCP/IP eccentric traffic. The GFR service not only guarantees minimum cell rate (MCR) throughput at the frame level but also supports a fair share of available bandwidth. We propose a high-speed novel fair buffer allocation (HS-NFBA) scheme through a FIFO queueing discipline, which further achieves low average cell queueing delay, and efficient hardware architecture supporting up to 10 Gbps synchronous transfer mode (STM)-64 line rate.
