Attaining the status of a Design Expert is what a lot of people tend to pursue, but not so many meet success in their pursuit of the CCDE. Becoming a Certified Design Expert is not really a matter of how hard you work, but how smart. You don't have all the time in the world to go making "your" mistakes, just so you could learn from them, or walking the well worn-out path and expecting different results. In this book, I have poured out my wealth of experience and expertise in the world of network design, this I have done in an easy to understand, non-textbook practical fashion without encapsulating the real thing in a sea of words. This book is written from the inside - out, for those who would like to pass both CCDE Written and Practical exams, or to gain deeper knowledge in network design. The book contains detailed systematic guide to learning: Many protocols and the technologies which are used in todays Service Provider, Enterprise, Datacenter, and Mobile operator real life network design. There are a lot of people out there who will try to teach Network Design, they do this haphazardly and at the end of the day they mess up the whole thing. This is not to say that there are no good tutors out there, but they are hard to find. And if you are lucky to find one, it is mostly theoretical and hardly any real-life practical stuff. It is all packed in here. The knowledge and insight, which I have carefully laid out in this book, will help you bag the CCDE certification and become the star that you deserve to be. Some of the areas that the book covers include: network design principles and all the best practices, tens of network design case studies, design review questions after each chapter, how real life networks look like and insight into how large companies and corporations design their network, techniques to will improve your strategic design thinking, CCDE Practical Lab design scenario, complementary study resources. Becoming a Design Expert is easy, but you have to work right and most importantly, you have to work smart.
The authoritative, business-driven study resource for the tough CCDE Practical Exam CCDE Study Guide is written and reviewed by CCDE engineers and helps you to both improve your design skills and to study for and pass the CCDE exam. Network design is an art, combining broad technology knowledge and experience. This book covers a broad number of technologies, protocols and design options, and considerations that can bring these aspects together and show how they can be used and thought about based on different requirements and business goals. Therefore, this book does not attempt to teach foundational technology knowledge, instead each section: Highlights, discusses, and compares the limitations and advantages of the different design options in terms of scalability, performance, flexibility, availability, complexity, security, and so on to simplify the job and help you understand what technology, protocol, or design options should be selected and why, based on the business or application requirements or to fix a broken design that need to be optimized Covers design aspects of different protocols and technologies, and how they map with different requirements Highlights drivers toward using these technologies whether it is intended for enterprise or service provider network, depending on the topic and technology Using a business-driven approach, CCDE Study Guide helps you analyze business and technical requirements and develop network designs that are based on these business needs and goals, taking into account both the technical and non-technical design constraints. The various “scenario-based” design examples discussed in this book will help you craft design approaches and requirements analysis on such topics as converged enterprise network architectures, service provider network architectures, and data centers. The book also addresses high availability, IPv6, multicast, QoS, security, and network management design considerations, presenting you with an in-depth evaluation of a broad range of technologies and environments. Whether you are preparing for the CCDE exam or simply wish to gain better insight into the art of network design in a variety of environments, this book helps you learn how to think like an expert network designer as well as analyze and compare the different design options, principles, and protocols based on different design requirements. Master a business-driven approach to designing enterprise, service provider, and data center networks Analyze the design impact of business, functional, and application requirements Learn from scenario-based examples, including converged enterprise networks, service provider networks, and cloud-based data centers Overcome design limitations and fix broken designs Review design options and considerations related to Layer 2 and Layer 3 control plane protocols Build designs that accommodate new services and applications Consider design options for modern campus networks, including network virtualization Design WAN edge and Internet edge blocks in enterprise networks Review the architectural elements of a service provider-grade network Plan MPLS VPN network environments, including L2VPN and L3VPN Interconnect different networks or routing domains Design traditional, virtualized, and cloud-based data center networks Interconnect dispersed data center networks to protect business continuity Achieve appropriate levels of operational uptime and network resiliency Integrate IPv6, multicast, QoS, security, and network management into your designs
