Abstract
This paper presents a novel generic weight-based network bandwidth sharing policy and an available bit rate (ABR) algorithm that achieves this policy. Our policy supports the minimum cell rate (MCR) requirement and peak cell rate (PCR) constraint of each connection and allocates network bandwidth among all connections based on a weight associated with each connection. To achieve this policy for ABR connections, we design an ABR algorithm which employs per virtual connection (VC) accounting to keep track of the state information of each VC. Our ABR algorithm is proven to provide guaranteed convergence to our generic weight-based rate allocation policy under any network configuration and any set of link distances. Simulation results show that our ABR algorithm has a fast convergence property.
