Guo et al (2009) BCube: A High Performance, Server-centric Network Architecture for Modular Data Centers (SIGCOMM)

BCube is a recursive structure so that:

• BCube(\(0\)) is a \(n\)-port switch connects \(n\) servers
• BCube(\(k\)) consists of \(n\) units of BCube(\(k-1\)) and \(n^k\) units of \(n\)-port switch, in total \(n^{k+1}\) servers and \((k+1)n^k\) switches

Building BCube(\(k\)) from BCube(\(k-1\)) are as follows: We number the BCube(\(k-1\)) from \(1\) to \(n\) and in each BCube(\(k-1\)), number the server from 1 to \(n^k\). Then, considering the \(n\) switches in the layer \(k\), we connect the \(i\)-th server in \(j\)-th BCube(\(k-1\)) to the \(j\)-th port of the \(i\)-th switch.
