WAN Optimization Fundamentals
IT organizations face pressure to increase productivity, improve application performance, support global collaboration, improve data protection, and minimize costs. In today’s WAN-centered environments, traditional LAN-oriented infrastructure approaches are insufficient to meet these goals. Application Acceleration and WAN Optimization Fundamentals introduces a better solution: integrating today’s new generation of accelerator solutions to efficiently and effectively scale networks beyond traditional capabilities while improving performance and minimizing costs through consolidation.
Ted Grevers and Joel Christner begin by reviewing the challenges network professionals face in delivering applications to globally distributed workforces. You learn how accelerators are transforming application business models, enabling IT departments to centralize and consolidate resources while also delivering consistently superior performance.
Grevers and Christner show how to identify network consumers, prioritize traffic, and guarantee appropriate throughput and response times to business-critical applications. You learn how to use quality of service techniques such as packet classification and marking and traffic policing, queuing, scheduling, and shaping.
Next, you compare options for integrating accelerators and optimization services into your network and for optimizing content delivery. The authors show how to address application protocol-related performance problems that cannot be resolved through compression or flow optimization alone. In the final chapter, the authors walk you through several real-world scenarios for utilizing accelerator technology.
Ted Grevers, Jr., is the solution manager for the Cisco® Video IPTV Systems Test and Architecture (C-VISTA) team. He has extensive experience in the content delivery network (CDN) market, focusing on enterprise and service provider content delivery and application optimization needs.
Joel Christner, CCIE® No. 15311, is the manager of technical marketing for the Cisco Application Delivery Business Unit (ADBU). He has extensive experience with application protocols, acceleration technologies, LAN/WAN infrastructure, and storage networking. Grevers and Christner are key contributors to the design and architecture of Cisco application delivery and application acceleration solutions.
