K-ary fat tree: three-layer topology (edge, aggregation and core):
- Each pod consists of (k/2)^2 servers & 2 layers of k/2 k-port switches
- Each edge switch connects to k/2 servers & k/2 aggr. switches
- Each aggr. switch connects to k/2 edge & k/2 core switches
- (k/2)^2 core switches that each one connects to k pods
A topology with 24 nodes and 43 links.
