Excerpts

Designing Cisco Network Service Architectures (ARCH) Designing Cisco Network Service Architectures (ARCH) IntroductionDesigning Cisco Network Service Architectures (ARCH), Second Edition, covers how to perform the conceptual, intermediate, and detailed design of a network infrastructure. This design supports network solutions over intelligent network services to achieve effective performance, scalability, and availability of the network. This book enables readers, applying solid Cisco network solution models and best design practices, to provide viable and stable enterprise internetworking solutions. In addition, the book has been written to help candidates prepare for the Designing Cisco Network Service Architectures Exam (642-873 ARCH). This exam is one of the requirements for the CCDP certification. This exam tests a candidate's knowledge of the latest development in network design and technologies, including network infrastructure, intelligent network services, and converged network solutions.Since the first edition was published in 2004, the ARCH course has changed to reflect the new exam requirements. This led to the immediate need for an update to this examination preparation text. Readers of the previous edition of Designing Cisco Network Architectures (ARCH) can use this text to update their knowledge and skill sets. Goals of This BookUpon completing this book, you will be able to meet these objectives: Introduce the Cisco Service-Oriented Network Architecture (SONA) framework, and explain how it addresses enterprise network needs for performance, scalability, and availability Describe how the Cisco Enterprise Architectures are used in the SONA framework for designing enterprise networks Create intermediate and detailed enterprise campus network, enterprise edge, and remote infrastructure designs that offer effective functionality, performance, scalability, and availability Create conceptual, intermediate, and detailed intelligent network service designs for network management, high availability, security, quality of service (QoS), and IP multicast Create conceptual, intermediate, and detailed virtual private network (VPN) designs Create conceptual, intermediate, and detailed voice over wireless network designs Prerequisite KnowledgeAlthough enthusiastic readers will tackle less-familiar topics with some energy, a sound grounding in networking is advised. To gain the most from this book, you should be familiar with internetworking technologies, Cisco products, and Cisco IOS Software features. You will find knowledge about the following topics helpful for your successful understanding of the material presented in this book: How to design the necessary services to extend IP addresses using variable-length subnet masking (VLSM), Network Address Translation (NAT), and route summarization How to implement appropriate networking routing protocols, such as Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway Protocol (BGP) on an existing internetwork How to redistribute routes between different routing protocols The required Cisco products and services that enable connectivity and traffic transport for a multilayer campus network The necessary services at each layer of the network to enable all users to ob
