Über dieses Buch

This book explores the challenges and opportunities in exploiting cloud technologies for 5G, ranging from radio access network (RAN) to the evolved packet core (EPC). With a specific focus on cloud RAN and EPC, the text carefully explains the influence of recent network technologies such as software defined networking (SDN), visualization, and cloud technologies in the evolution of architecture for future mobile networks. The book discusses the causes, benefits and challenges of cloud RAN and its interplay with other evolving technologies for future mobile networks.
Researchers and professionals involved in mobile technology or cloud computing will find this book a valuable resource. The text is also suitable for advanced-level students studying all types of networking.

Chapter 1. Introduction

Abstract

Over the past decades, the telecommunications industry has migrated from legacy telephony networks to telephony networks based on an IP backbone. IP-based networks have offered operators the opportunity to access previously untapped networks/subscribers to offer innovative products and services, and stimulate a new wave of revenue generation.

Chapter 2. Virtualization and Cloud Computing

Abstract

In an effort to move the networking industry from today’s manual configuration to embrace automated solutions that are coordinated with the rest of the infrastructure, there have been several emerging technologies in the past few years, chief among them are network virtualization (NV), network functions virtualization (NFV), and software-defined networking (SDN).

Chapter 3. Software-Defined Networks Principles and Use Case Scenarios

Abstract

With the emerging services and business models driven by open devices and applications (app stores), service providers are faced with new challenges of reducing total cost of ownership (TCO), improve average revenue per user (ARPU), and customer retention. The software defined networking (SDN) paradigm provides a promising way to address these challenges with four fundamental principles, viz., decoupling of control and forwarding planes for improved scaling to reduce TCO, open APIs for network programmability/flexibility for service velocity and innovation, network virtualization for resource optimization and open flow for intelligent flow management. In this chapter, we provide a review of the SDN technology and business drivers, describe the high-level SDN architecture and principles, and give three scenarios of its use cases in mobile access aggregation networks and the cloud networks. Furthermore, we provide discussions on the design implementation considerations of SDN in the mobile networks and the cloud, in comparison with traditional networks.

Chapter 4. Virtualizing the Network Services: Network Function Virtualization

Abstract

Network function virtualization (NFV) is rapidly emerging as the de facto approach operators will use to deploy their networks. NFV leverages on cloud computing principles to change the way NFs like gateways and middleboxes are offered. As opposed to today’s tightly coupling between the NF software and dedicated hardware, NFV concept requires the virtualization of NFs allowing them to run on generalized hardware.

Chapter 5. SDN/NFV Telco Case Studies

Abstract

In this chapter, we introduce two case studies of SDN and NFV in the mobile core networks, which is a foundation of the next-generation mobile core network (5G).

Chapter 6. Radio Access Network Evolution

Abstract

Today, mobile network operators have a variety of options for the means of providing more coverage, capacity, and services to their subscribers. Alongside the advancement of wireless standards to provide higher spectral efficiency, vendors have released a wide range of radio access nodes for network densification.

Chapter 7. Cloud RAN

Abstract

In principle, C-RAN is a RAN architecture that changes the traditional RAN architecture in a way that it can take advantage of technologies like cloud computing, virtualization, multi-user MIMO, and software-defined networking.
