Routing techniques in data center networks

Abstract

This chapter deals with the problem of data forwarding and routing in data center networks (DCNs). Different types of routing and forwarding techniques in DCNs are discussed in this chapter. We provide an overview of some of the existing forwarding and routing schemes in DCNs and classify them based upon different parameters such as protocols which take into account the underlying physical topology, routing protocols to conserve energy in data centers, and traffic-sensitive routing algorithms. In addition to that, we also survey some of the existing routing protocols for content distribution networks (CDNs). We conclude this chapter by outlining some of the challenges and open issues in designing efficient routing techniques for such networks.
