Abstract
A system for bandwidth estimation includes an interface and a processor. The interface communicates with a fat-tree (FT) network including leaf switches belonging to a bottom level, spine switches belonging to a top level and intermediate switches belonging to one or more intermediate levels. The processor estimates an available bandwidth between first and second leaf switches, by identifying a first bottom-to-top sub-tree to which the first leaf switch belongs, and a second bottom-to-top sub-tree to which the second leaf switch belongs, determining path counts for at least some of the switches in the intermediate levels, wherein a path count for a switch is indicative of a number of paths that each passes via the switch, reaches the first leaf switch via the first bottom-to-top sub-tree, and reaches the second leaf switch via the second bottom-to-top sub-tree, and estimating the available bandwidth based on the path counts.
