       5G Mobile Networks:A Systems Approach

       Synthesis Lectures on Network Systems

      Editor

       Larry Peterson, Open Networking Foundation and Princeton University

      Synthesis Lectures on Network Systems is edited by Larry Peterson, CTO of the Open Networking Foundation and Robert E. Kahn Professor Emeritus at Princeton University. The series publishes 75- to 200-page books covering a systems approach to networking and the distributed computing systems built around networks. The major emphasis is placed on the design and implementation of networks, distributed systems, and scalable cloud services in order to address a combination of traditional networking topics (e.g., congestion control, access control, addressing/routing, virtualization, real-time streaming, and mobility) and universal systems concerns (e.g., scalability, reliability, availability, security, feature velocity, and manageability). Although not a strict requirement, the series prioritizes empirical results, real-world use cases, and experience building systems. The scope will largely follow the purview of premier networking and systems conferences, such as SIGCOMM, NSDI, SOSP, and OSDI.

       ABSTRACT

      This book describes the 5G mobile network from a systems perspective, focusing on the fundamental design principles that are easily obscured by an overwhelming number of acronyms and standards definitions that dominate this space. The book is written for system generalists with the goal of helping bring up to speed a community that understands a broad range of systems issues (but knows little or nothing about the cellular network) so it can play a role in the network’s evolution. This is a community that understands both feature velocity and best practices in building robust scalable systems, and so it has an important role to play in bringing to fruition all of 5G’s potential.

      In addition to giving a step-by-step tour of the design rationale behind 5G, the book aggressively disaggregates the 5G mobile network. Building a disaggregated, virtualized, and software-defined 5G access network is the direction the industry is already headed (for good technical and business reasons), but breaking the 5G network down into its elemental components is also the best way to explain how 5G works. It also helps to illustrate how 5G might evolve in the future to provide even more value.

      An open source implementation of 5G serves as the technical underpinning for the book. The authors, in collaboration with industrial and academic partners, are working towards a cloud-based implementation that takes advantage of both Software-Defined Networking (SDN) and cloud-native (microservice-based) architectures, culminating in a managed 5G-enabled EdgeCloud-as-a-Service built on the components and mechanisms described throughout the book.
