The sensible advisor to development resilient and hugely on hand IP networks 

  • Learn from an all-in-one advent to new gains and advancements in construction a resilient IP network
  • Enable your company to fulfill inner service-level agreements (SLAs) for mission-critical resources
  • Understand how a resilient IP community may also help in offering mission-critical info comparable to video and voice services
  • Work with configuration examples which are in keeping with real-world matters and shopper requirements
  • Get information and top practices from box group of workers who've labored on many of the biggest networks with stringent uptime specifications and SLAs

More businesses are development networks with the purpose of utilizing them to behavior enterprise. as the community has turn into the sort of strategic enterprise device, its availability is of maximum value to businesses and their carrier companies. The demanding situations for the pros answerable for those networks comprise making sure that the community continues to be up for all time, maintaining abreast of the newest applied sciences that support keep uptime, and reacting to ever-increasing denial-of-service (DoS) attacks.


Building Resilient IP Networks is helping you meet these demanding situations. This sensible consultant to construction hugely to be had IP networks captures the essence of applied sciences that give a contribution to the uptime of networks. You achieve a transparent realizing of the way to accomplish community availability by using instruments, layout technique, and Cisco IOS® Software.


With Building Resilient IP Networks, you study misconceptions approximately five-nines availability and discover ways to concentration your recognition at the genuine concerns: appreciating the constraints of the protocols, realizing what has been performed to enhance them, and maintaining abreast of these alterations. construction Resilient IP Networks highlights the significance of getting a modular method of development an IP community and, most vital, illustrates how a modular layout contributes to a resilient community. You learn the way an IP community will be damaged right down to a number of modules and the way those modules interconnect with each other. you then discover new community resiliency beneficial properties which have been built lately, labeled with recognize to the layout modules.


Building Resilient IP Networks is correct to either company and repair supplier buyers of all sizes. whether the community connects to the net, fortifying IP networks for optimum uptime and prevention of assaults is crucial for anyone’s business.


This booklet is a part of the Networking know-how sequence from Cisco Press®, which deals networking pros invaluable details for developing effective networks, figuring out new applied sciences, and construction winning careers.

Introduction Over the years, many excellent books have been written on IP technology, and these books tend to focus on a specific topic, such as Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP). However, building a resilient IP network requires a holistic approach to design and implementation. Various building blocks need to work together, most of which have seen enhancements and new features introduced. These features are scattered, mostly in the form of numerous Requests For Comments (RFCs), IOS features and documentations, and many Cisco Technical Assistance Center (TAC)-authored white papers.

So does that mean that the system described in the preceding paragraphs is not five-nines certified? The answer is that PBX is still a five-nines system. It would take a shutdown of the entire system to constitute a downtime. That is why PBX vendors can always meet the so-called five-nine standard舒they simply provide enough redundant power supply and controller cards. 94 percent. 999 percent uptime. When superimposing the concept of the GR-512-Core documents onto a data network, you encounter arguments about what constitutes IP network availability.

Improvements to the Exterior Gateway Protocol and addressing and routing solutions for redundancy are highlighted. 舦 Chapter 8, 舠WAN Module,舡 showcases improvements made to the various traditional WAN connectivity technologies. 舦 Chapter 9, 舠Data Center Module,舡 examines factors that influence data center network design.
