Rate-based headend-controlled bandwidth allocation in unidirectional bus metropolitan area networks

The authors introduce and analyze a protocol for unidirectional bus networks in which bandwidth allocation and access fairness are adaptively controlled by the head end of the bus on the basis of traffic measurements. The proposed protocol can control the admitted traffic of a particular type to a desired fraction of the bus capacity and at the same time enforce access fairness faster than other existing protocols, such as the one used in the recently approved IEEE 802.6 metropolitan area network (MAN) standard
