Über dieses Buch

This SpringerBrief presents a survey of data center network designs and topologies and compares several properties in order to highlight their advantages and disadvantages. The brief also explores several routing protocols designed for these topologies and compares the basic algorithms to establish connections, the techniques used to gain better performance, and the mechanisms for fault-tolerance. Readers will be equipped to understand how current research on data center networks enables the design of future architectures that can improve performance and dependability of data centers. This concise brief is designed for researchers and practitioners working on data center networks, comparative topologies, fault tolerance routing, and data center management systems. The context provided and information on future directions will also prove valuable for students interested in these topics.

Chapter 1. Introduction

Abstract

In this chapter, we give the basic introduction to data center networks. We briefly mention the typical characteristics of data center applications that dictate the expectations from the underlying data center networks. We then briefly review the data center network requirements presented in the literature, that need to be met by future data center networking architectures.

Chapter 2. Data Center Network Topologies: Current State-of-the-Art

Abstract

Current state-of-the-art data center networks are primarily implemented using tree-based topologies. An alternative is to use a leaf-spine configuration which is based on the folded-Clos network. While these approach meet the demands of the current DCN, they are not suited to meet future demands. This chapter reviews some of the salient features of the approaches and points out their shortcomings.

Chapter 3. Data Center Network Topologies: Research Proposals

Abstract

Several new data center network topologies have been proposed by researchers, aimed at addressing many of the shortcomings of the current DCN. This chapter reviews some of the representative topologies. We classify the topologies based on their characteristics into fixed and flexible topologies. We then review their properties in terms of scale, performance and hardware redundancy.

Chapter 4. Routing Techniques

Abstract

Each specific DCN topology requires the design of suitable routing techniques to accommodate the unique structure and properties of the topology. In this chapter we introduce some of these techniques for the topologies we discussed in previous chapters, and give a comparison on these techniques from various perspectives.

Chapter 5. Performance Enhancement

Abstract

DCNs offer rich connectivity and high bandwidth for applications. In this chapter we review the solutions to make better use of the network capacity, and enhance the performance of DCN. These solutions are proposed with a specific topology design in mind, yet they still offer useful inspiration for other topologies.

Chapter 6. Fault-Tolerant Routing

Abstract

Failures are inevitable considering the large scale of DCN. Most DCN topologies are designed with redundancy to recover from failures and maintain performance. We introduce the taxonamy of common failures in DCNs, and review the fault-tolerance techniques. An overview of the fault-tolerance characteristics of some DCN topologies based on simulation results is also presented.

Chapter 7. Conclusions

Abstract

In this book, we examined data center networks in detail, focusing on some representative topologies of data center networks. First, we reviewed the current state-of-the-art for data center topologies. Then, we introduced several of the newly proposed topologies that have appeared in research and academic literature. We categorized these topologies according to their features. We analyzed several of the properties of these topologies, in terms of their scalability, performance and hardware redundancy and presented some performance results by comparing various metrics.
