This book is a straightforward discussion of the concepts, principles, and processes of many protocols in the TCP/IP protocol suite and how they are supported by Windows Server 2008 and Windows Vista. The focus of this book is on Internet Protocol version 4 (IPv4), referred to as Internet Protocol (IP), and associated transport and network infrastructure support protocols. This book provides an overview of Internet Protocol version 6 (IPv6), but not in-depth technical details. For more information about IPv6 and its implementation in Windows Server 2008 and Windows Vista, see Understanding IPv6, Second Edition by Joseph Davies (Redmond, Wash.: Microsoft Press, 2008; ISBN 978-0735624467).

This book is primarily a discussion of protocols (what you might see on the wire during communication) and processes (how things work under the covers), rather than a discussion of planning, configuration, deployment, management, or application development. For a discussion of TCP/IP planning, configuration, deployment, and management, see Windows Server® 2008 Networking and Network Access Protection (NAP) (Redmond, Wash.: Microsoft Press, 2008; ISBN 978-0735624221), Help And Support for Windows Server 2008, and the Windows Server 2008 TechCenter at http://technet.microsoft.com/windowsserver/2008. For a discussion of TCP/IP application development using Windows Sockets, see the Microsoft Developer Network at http://msdn.microsoft.com.

This book does not contain code-level details of the Microsoft implementation of TCP/IP in Windows Server 2008 and Windows Vista, such as internal structures, tables, buffers and their use, or coding logic. These details are only of interest to a relative handful of readers and are not published for security reasons and to protect Microsoft intellectual property. However, this book does contain details of how the Microsoft implementation of TCP/IP in Windows Server 2008 and Windows Vista works for described TCP/IP processes and how to modify default behaviors with registry values and Netsh.exe tool commands.

An Under-the-Hood Guide to the Power of Xen Hypervisor Internals

The Definitive Guide to the Xen Hypervisor is a comprehensive handbook on the inner workings of XenSource’s powerful open source paravirtualization solution. From architecture to kernel internals, author David Chisnall exposes key code components and shows you how the technology works, providing the essential information you need to fully harness and exploit the Xen hypervisor to develop cost-effective, highperformance Linux and Windows virtual environments.

 

Granted exclusive access to the XenSource team, Chisnall lays down a solid framework with overviews of virtualization and the design philosophy behind the Xen hypervisor. Next, Chisnall takes you on an in-depth exploration of the hypervisor’s architecture, interfaces, device support, management tools, and internals—including key information for developers who want to optimize applications for virtual environments. He reveals the power and pitfalls of Xen in real-world examples and includes hands-on exercises, so you gain valuable experience as you learn.

This insightful resource gives you a detailed picture of how all the pieces of the Xen hypervisor fit and work together, setting you on the path to building and implementing a streamlined, cost-efficient virtual enterprise.

Coverge includes
