Huawei is one of the leading ICT solution providers worldwide. Our vision is to enrich life through communication, and it is with this vision that we are able to leverage our ICT technologies and experience to help everyone bridge the digital divide and become a part of the information society so that all may enjoy the benefits of ICT services. We endeavor to popularize ICT, facilitate education, and cultivate ICT talents, providing people with the tools necessary to build a fully connected world.To help ICT practitioners hone their skills and gain practical experience, Huawei launched the industry's first freely available network simulation platform in September 2012. Known as the enterprise network simulation platform (eNSP), it has been downloaded millions of times and has become the cornerstone of learning how to operate network devices. HCNA Networking Experiment Guide can be used in conjunction with eNSP to deepen your understanding of the practical aspects ofnetworking. HCNA Networking Study Guide perfectly complements eNSP, focusing on the principles of network technologies and the theory behind ICT. Integrating practice and theory is essential to building in-depth ICT knowledge.This book is the culmination of efforts by Dr. Jiang Yonghong and his writing team. Dr. Jiang is a senior technical expert in Huawei and has worked with us for over 10 years. Before joining Huawei, Dr. Jiang gained many years of teaching experience in both domestic and international universities. He therefore has a deep understanding of how knowledge can be taught and mastered. Logic is important for explaining principles, as too is the accuracy of information—the very essence of this is embodied in HCNA Networking Study Guide.
