A new bandwidth sharing scheme for non-responsive multicast flows

Abstract

In this work, we propose a new active queue management mechanism called MFQ (multicast fair queuing) for multicast flows. MFQ is independent of the inter-multicast fairness policy and it interacts with a multicast bandwidth allocation module that can implement either a multicast fairness policy or a multicast pricing model and tries using a single FIFO queue to achieve the expected allocation which may depend on the number of downstream receivers. We perform simulations to evaluate the performance of MFQ for different bandwidth allocation schemes. Results obtained suggest that MFQ achieves the expected allocation for non-responsive multicast flows.
