Fair queuing with in/out bit in core stateless networks

Several fair queuing schemes have been proposed for core stateless networks. They can achieve fairer bandwidth allocation than RED (random early detection). However, there have not been any studies that consider in/out bit usage. This paper proposes a way to extend the schemes that have been proposed for core stateless networks to allow the support of in/out bit usage. The extended schemes are suitable for realizing guaranteed rate (GR) service, which provides each user with a minimum guaranteed rate and a fair share of the residual bandwidth. We present the performance of one of the extended schemes and compare the scheme to RIO (RED with in/out bit) in terms of fair bandwidth allocation.
