End-to-End QoS Network Design

En savoir plus sur le livre

This authoritative guide provides new best practices, technical strategies, and proven designs for maximizing Quality of Service (QoS) in complex networks. It has been thoroughly updated to reflect the latest applications, hardware, software, and tools relevant to modern networks. The focus is on complex traffic mixes, increased mobile device usage, wireless access, advanced communications, and video, addressing the growing diversity of video traffic, including passive streaming, interactive video, and immersive videoconferences. The authors introduce QoS technologies in high-to-mid-level technical detail, covering protocols, tools, and standards. They explore new QoS demands, reasons to reevaluate current designs, and strategic recommendations. With extensive experience, they provide detailed insights into campus wired and wireless QoS design, next-generation wiring closets, data center QoS, Internet and WAN edge, and IPsec VPNs. Readers will master a step-by-step approach to successful QoS deployment, implement Cisco-validated designs, and apply best practices for classification, marking, policing, and congestion management. The guide emphasizes leveraging Cisco Application Visibility and Control for deep-packet inspection and optimizing QoS in rich-media networks using Cisco Catalyst switches. It also covers designing wireless networks for voice and video, achieving zero packet loss in data centers, and utilizing new ind
