The practical guide to building resilient and highly available IP networks Learn from an all-in-one introduction to new features and developments in building a resilient IP network Enable your organization to meet internal service-level agreements (SLAs) for mission-critical resources Understand how a resilient IP network can help in delivering mission-critical information such as video and voice services Work with configuration examples that are based on real-world issues and customer requirements Get tips and best practices from field personnel who have worked on some of the largest networks with stringent uptime requirements and SLAs More companies are building networks with the intention of using them to conduct business. Because the network has become such a strategic business tool, its availability is of utmost importance to companies and their service providers. The challenges for the professionals responsible for these networks include ensuring that the network remains up all the time, keeping abreast of the latest technologies that help maintain uptime, and reacting to ever-increasing denial-of-service (DoS) attacks. Building Resilient IP Networks helps you meet those challenges. This practical guide to building highly available IP networks captures the essence of technologies that contribute to the uptime of networks. You gain a clear understanding of how to achieve network availability through the use of tools, design strategy, and Cisco IOS® Software. With Building Resilient IP Networks, you examine misconceptions about five-nines availability and learn to focus your attention on the real issues: appreciating the limitations of the protocols, understanding what has been done to improve them, and keeping abreast of those changes. Building Resilient IP Networks highlights the importance of having a modular approach to building an IP network and, most important, illustrates how a modular design contributes to a resilient network. You learn how an IP network can be broken down to various modules and how these modules interconnect with one another. Then you explore new network resiliency features that have been developed recently, categorized with respect to the design modules. Building Resilient IP Networks is relevant to both enterprise and service provider customers of all sizes. Regardless of whether the network connects to the Internet, fortifying IP networks for maximum uptime and prevention of attacks is mandatory for anyone’s business. This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

This book summarizes the key Quality of Service technologies deployed in telecommunications networks: Ethernet, IP, and MPLS. The QoS of the network is made up of two parts: fault and resource management. Network operation quality is among the functions to be fulfilled in order to offer QoS to the end user. It is characterized by four parameters: packet loss, delay, jitter or the variation of delay over time, and availability. Resource management employs mechanisms that enable the first three parameters to be guaranteed or optimized. Fault management aims to ensure continuity of service.

This book constitutes the refereed proceedings of the 7th IFIP WG 6.6 International Conference on Autonomous Infrastructure, Management, and Security, AIMS 2013, held in Barcelona, Spain, in June 2013. The 11 full papers presented were carefully reviewed and selected from 32 submissions. The volume also includes 7 papers presented at the AIMS Ph.D. workshop. They were reviewed and selected from 14 submissions. The papers are organized in topical sections on traffic engineering and quality-of-service; monitoring and modeling; security management; content distribution and multimedia; autonomous management; and monitoring mechanisms.

This book represents the combined peer-reviewed proceedings of the ninth International Symposium on Intelligent Distributed Computing – IDC’2015, of the Workshop on Cyber Security and Resilience of Large-Scale Systems – WSRL’2015, and of the International Workshop on Future Internet and Smart Networks – FI&SN’2015. All the events were held in Guimarães, Portugal during October 7th-9th, 2015. The 46 contributions published in this book address many topics related to theory and applications of intelligent distributed computing, including: Intelligent Distributed Agent-Based Systems, Ambient Intelligence and Social Networks, Computational Sustainability, Intelligent Distributed Knowledge Representation and Processing, Smart Networks, Networked Intelligence and Intelligent Distributed Applications, amongst others.

This book focuses on the design goals (i.e., key features), architectures, and practical applications of switch/routers in IP networks. The discussion includes some practical design examples to illustrate how switch/routers are designed and how the key features are implemented. Designing Switch/Routers: Architectures and Applications explains the design and architectural considerations as well as the typical processes and steps used to build practical switch/routers. The author describes the components of a switch/router that are used to configure, manage, and monitor it. This book discusses the advantages of using Ethernet in today’s networks and why Ethernet continues to play a large role in Local Area Network (LAN), Metropolitan Area Network (MAN), and Wide Area Network (WAN) design. The author also explains typical networking applications of switch/routers, particularly in enterprise and internet service provider (ISP) networks. This book provides a discussion of the design of switch/routers and is written to appeal to undergraduate and graduate students, engineers, and researchers in the networking and telecom industry as well as academics and other industry professionals. The material and discussion are structured to serve as standalone teaching material for networking and telecom courses and/or supplementary material for such courses.

Master Modern Networking by Understanding and Solving Real Problems Computer Networking Problems and Solutions offers a new approach to understanding networking that not only illuminates current systems but prepares readers for whatever comes next. Its problem-solving approach reveals why modern computer networks and protocols are designed as they are, by explaining the problems any protocol or system must overcome, considering common solutions, and showing how those solutions have been implemented in new and mature protocols. Part I considers data transport (the data plane). Part II covers protocols used to discover and use topology and reachability information (the control plane). Part III considers several common network designs and architectures, including data center fabrics, MPLS cores, and modern Software-Defined Wide Area Networks (SD-WAN). Principles that underlie technologies such as Software Defined Networks (SDNs) are considered throughout, as solutions to problems faced by all networking technologies. This guide is ideal for beginning network engineers, students of computer networking, and experienced engineers seeking a deeper understanding of the technologies they use every day. Whatever your background, this book will help you quickly recognize problems and solutions that constantly recur, and apply this knowledge to new technologies and environments.
