While tagging-based variable-bit-rate (VBR) and guaranteed-frame-rate (GFR) guarantee a minimum cell rate for asynchronous transfer mode (ATM) traffic, they cannot explicitly guarantee the throughput on the transmission control protocol (TCP) layer when TCP/IP (internet protocol) is used over the ATM network. The virtual channel (VC) throughput of TCP over these service categories has been analyzed assuming that VBR uses first in first out queuing and GFR uses per VC queueing with weighted round robin scheduling. Simulation showed that these service categories can guarantee a minimum throughput on the TCP layer, and that GFR more fairly distributes the bandwidth than does VBR.
