This book shows how SRv6 can be used in real-world network deployments, providing real-world project cases from multiple carriers and enterprises. Segment Routing (SR) has matured significantly over the past decade. Its derivative, SR over IPv6 dataplane (SRv6), has experienced rapid development in recent years and has gained wide acceptance among carriers. However, despite the growing interest in SRv6 deployment and the desire for detailed information, no reference material is available. This book aims to fill this gap by providing a comprehensive description of how SRv6 can be used in real network deployment scenarios. Written by participants in Huawei's SRv6 project, this book provides an in-depth look at the project's solution design and deployment guidelines. It also provides insights into the latest progress of SRv6 header compression standards and provides examples. This book is a valuable reference for academics and students majoring in data communications, as well as data communications professionals and managers responsible for network planning and design, and network operation and maintenance management.
