A distributed congestion avoidance scheme, the End-to-End Rate Control Algorithm (EERCA), has been proposed for Available Bit Rate (ABR) service. In this work, we enhance EERCA by replacing the Queue Occupancy Reduction with the queuing delay control (QDC), which manipulates the queue occupancy more efficiently with less functional complexity. Furthermore, it alleviates per-VC accounting requirement and thus reduces the complexity of a switch. From both the analysis and the simulation, it shows that the proposed virtual queue occupancy precisely reflects the variation of the actual queue occupancy. This enhanced EERCA features higher efficiency and more stable queue occupancy than the original algorithm.
