There are usually more questions than answers when you’re dealing with network performance in a production network environment It would be great if there were standard answers to these questions, along with a standard way to solve slow network performance The open source network performance tools presented in this book can help the network administrator determine... network, and identify the areas of the network that could be improved to increase performance Often, network bottlenecks can be found, and simply reallocating the resources on a network can greatly improve performance, without the addition of expensive new network equipment Knowing the elements of network performance will help you better understand how the network performance tools work, and how to... book is to help network administrators and technicians monitor and analyze network performance Often it is not easy to determine what causes network performance problems The tools presented in the first two sections of the book can be used in the production network to help identify the cause of network performance issues The text explains how to install and configure each tool, and describes how to use... tools that can monitor and analyze network behavior, to identify the cause of network performance problems and determine how to quickly (and usually, cheaply) fix them With the explosion of Open Source software in recent years, many free applications are becoming available that can help the average network administrator Usually these applications can be easily downloaded, configured, and used to help determine . w1 h1" alt=""
