Performance analysis of feedback synchronization for multicast ABR flow control Conference Paper uri icon

abstract

  • We present a balanced and unbalanced binary-tree model to explore the delay performance of feedback synchronization algorithms for multicast ABR flow control. Using this model, we analyze the feedback-delay performance scalability of the Soft-Synchronization Protocol (SSP), which derives a single `consolidated' RM (Resource Management) cell at each multicast branch-point from feedback RM-cells of different downstream branches that are not necessarily responses to the same forward RM-cell. In contrast with the other existing schemes, SSP is shown to be able to effectively support synchronization of feedback RM-cells and make the effective RM-cell roundtrip time (RTT) virtually independent of the multicast-tree's topology. Also derived is the optimal RM-cell update interval for SSP to minimize RM-cell RTTs for a given multicast tree.
