Correction to: Chapter 12 in: F. Testa, L. Pavesi (eds.), Optical Switching in Next Generation Data Centers, https://doi.org/10.1007/978-3-319-61052-8_12

The chapter was inadvertently published with an error. In page 246, line 33, the formula O[log2N] is incorrect. It should be O[N log2N]. The same has been updated.
