Chapter 13

Data Center Networks

The content of this chapter is mainly divided into five topics: data center network (DCN) hardware, DCN terms, DCN metrics, DCN topologies, and characteristics of a cloud DCN. In terms of DCN topology, it starts with basic tree topology, which is highly recommended by one of the network equipment vendors, Cisco, and then the chapter discusses the fat tree, DCell, BCube, VL2, butterfly, and dragonfly topologies. Again, the main aim of these discussions is to highlight characteristics of each topology and associated costs for business needs. The section on cloud DCNs in this chapter covers four types of network: management, kernel, virtual machine, and virtualized storage.
