Best-practice QoS designs for protecting voice, video, and critical data while mitigating network denial-of-service attacks

• Understand the service-level requirements of voice, video, and data applications
• Examine strategic QoS best practices, including Scavenger-class QoS tactics for DoS/worm mitigation
• Learn about QoS tools and the various interdependencies and caveats of these tools that can impact design considerations
• Learn how to protect voice, video, and data traffic using various QoS mechanisms
• Evaluate design recommendations for protecting voice, video, and multiple classes of data while mitigating DoS/worm attacks for the following network infrastructure architectures: campus LAN, private WAN, MPLS VPN, and IPSec VPN

Quality of Service (QoS) has already proven itself as the enabling technology for the convergence of voice, video, and data networks. As business needs evolve, so do the demands for QoS. The need to protect critical applications via QoS mechanisms in business networks has escalated over the past few years, primarily due to the increased frequency and sophistication of denial-of-service (DoS) and worm attacks.

End-to-End QoS Network Design is a detailed handbook for planning and deploying QoS solutions to address current business needs. This book goes beyond discussing available QoS technologies and considers detailed design examples that illustrate where, when, and how to deploy various QoS features to provide validated and tested solutions for voice, video, and critical data over the LAN, WAN, and VPN.

The book starts with a brief background of network infrastructure evolution and the subsequent need for QoS. It then goes on to cover the various QoS features and tools currently available and comments on their evolution and direction. The QoS requirements of voice, interactive and streaming video, and multiple classes of data applications are presented, along with an overview of the nature and effects of various types of DoS and worm attacks. QoS best-practice design principles are introduced to show how QoS mechanisms can be strategically deployed end-to-end to address application requirements while mitigating network attacks. The next section focuses on how these strategic design principles are applied to campus LAN QoS design. Considerations and detailed design recommendations specific to the access, distribution, and core layers of an enterprise campus network are presented. Private WAN QoS design is discussed in the following section, where WAN-specific considerations and detailed QoS designs are presented for leased-lines, Frame Relay, ATM, ATM-to-FR Service Interworking, and ISDN networks. Branch-specific designs include Cisco® SAFE recommendations for using Network-Based Application Recognition (NBAR) for known-worm identification and policing. The final section covers Layer 3 VPN QoS design-for both MPLS and IPSec VPNs. As businesses are migrating to VPNs to meet their wide-area networking needs at lower costs, considerations specific to these topologies are required to be reflected in their customer-edge QoS designs. MPLS VPN QoS design is examined from both the enterprise and service provider's perspectives. Additionally, IPSec VPN QoS designs cover site-to-site and teleworker contexts.

Whether you are looking for an introduction to QoS principles and practices or a QoS planning and deployment guide, this book provides you with the expert advice you need to design and implement comprehensive QoS solutions.

Every graphics professional worth his or her salt knows the importance of color management. No matter how much thought artist and client put into the color scheme for a given project, all of that work is for naught if you can't get your results to match your expectations. Enter Real World Color Management, Second Edition. In this thoroughly updated under-the-hood reference, authors Bruce Fraser, Chris Murphy, and Fred Bunting draw on their years of professional experience to show you everything you need to know about color management. Whether your final destination is print, Web, or film, Real World Color Management, Second Edition takes the mystery out of color management, covering everything from color theory and color models to understanding how devices interpret and display color. You'll find expert advice for building and fine-tuning color profiles for input and output devices (digital cameras and scanners, displays, printers, and more), selecting the right color management workflow, and managing color within and across major design applications. Get Real World Color Management, Second Edition--and get ready to dazzle!

Este libro es una fascinante exploración sobre la naturaleza de la identidad cultural estadounidense, todavía en estado de shock tras los acontecimientos del 11 de septiembre de 2001.
De hecho, la devoción patriótica que siguió a los atentados se plasmó, entre otras cosas, en la venta de 250.000 banderas en unos conocidos grandes almacenes a lo largo de un solo día. Pero esta súbita reivindicación de la enseña nacional era sólo la evidencia física de algo mucho más importante: el renacimiento del orgullo en gran parte del pueblo de Estados Unidos, un sentimiento que había permanecido en estado de letargo desde hacía mucho tiempo. Para algunos todo se redujo a los McDonalds, a Walt Disney y al béisbol. Para otros, la reivindicación de esos valores debía remontarse a los primeros británicos que se establecieron en aquellas tierras, a la que legaron su cultura y su lengua. Para los afroamericanos y los latinos, sin embargo, no se trató de nada de todo esto.
Estados Unidos ha debido lidiar desde sus primeros días con los problemas de asimilación que supone la existencia en su territorio de culturas distintas. No obstante, hoy debe enfrentarse a una situación aún más peliaguda: la facilidad con que los inmigrantes pueden mantener los vínculos afectivos con su cultura de origen ?llamadas a larga distancia, emisoras de televisión en su propio idioma, billetes de avión a muy bajo precio--, con el distanciamiento que ello supone respecto a los nuevos valores de su país de adopción.
¿Quiénes somos? es uno de los libros más importantes de los últimos tiempos, una investigación a la vez histórica y cultural que, como los trabajos previos de su autor, provocará sin duda un encendido debate político e intelectual.
