Abstract

To deal with the widespread use of cloud services and the unprecedented traffic growth, the scale of the Data Center has importantly increased. Therefore, it is crucial to design novel efficient network architectures able to satisfy the requirements on bandwidth. As a key physical infrastructure, Data Center Network (DCN) designing has widely been a hot research focus.

This chapter reviews the main DCN architectures propounded in the literature. To do so, a taxonomy of DCN designs will be proposed, while analyzing in depth each structure of the given classification. Then, we will provide a qualitative comparison between these different DCN groups. Finally, we will present hybrid DCN architecture based on wired and wireless architecture.

1.1 Taxonomy of DCN Architectures

In this section, we present a taxonomy of the existent Data Center Network (DCN) architectures with a detailed review of each drawn class. In general, several criteria have to be considered to design robust DCNs, namely, high network performance, efficient resource utilization, full available bandwidth, high scalability, easy cabling, etc. To deal with the aforementioned challenges, a panoply of solutions have been designed. Mainly, we can distinguish two research directions. In the first one, wired DCN architectures have been upgraded to build advanced cost‐effective topologies able to scale up data centers. The second approach has resorted to deploying new network techniques within the existing DCN so as to handle the challenges encountered in the prior architectures. Hereafter, we will give a detailed taxonomy of these techniques.

1.1.1 Classification of DCN Architectures

With regard to the aforementioned research directions, we can identify three main groups of DCN architectures, namely, switch‐centric DCN, server‐centric DCN, and enhanced DCN. Each group includes a variety of categories that we will detail hereafter.

• Switch‐centric DCN architecture: switches are, mostly, responsible for network‐related functions, whereas the servers handle processing tasks. The focus of such a design is to improve the topology so as to increase network scale, reduce oversubscription, and speed up flow transmission. Switch‐centric architectures can be classified into three main categories according to their structural properties:
  1. Traditional tree‐based DCN architecture: represents a specific kind of switch‐centric architecture, where switches are linked in a multiroo...
