Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly.That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right.Thoroughly revised and expanded, Cisco IOS Cookbook, 2nd Edition, adds sections on MPLS, Security, IPv6, and IP Mobility, and presents solutions to the most common configuration problems, including:Configuring interfaces of many types, from serial to ATM and Frame RelayConfiguring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP)Configuring authenticationConfiguring other services, including DHCP and NTPSetting up backup links, and using HSRP to configure backup routersManaging the router, including SNMP and other solutionsUsing access lists to control the traffic through the routerIf you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced--if you've just been given responsibility for managing a network with Cisco routers--this book could be a job-saver.

Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to:Make Fewer HTTP RequestsUse a Content Delivery NetworkAdd an Expires HeaderGzip ComponentsPut Stylesheets at the TopPut Scripts at the BottomAvoid CSS ExpressionsMake JavaScript and CSS ExternalReduce DNS LookupsMinify JavaScriptAvoid RedirectsRemove Duplicates ScriptsConfigure ETagsMake Ajax CacheableIf you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable."e;If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore."e;-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector"e;Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance."e;-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation
