Book Synopsis Enterprise Network Convergence by : Vidhumana Sridharan
Download or read book Enterprise Network Convergence written by Vidhumana Sridharan and published by . This book was released on 2007 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: "During the past two decades, telecommunications has evolved a great deal. In the eighties, people were using television, radio and telephone as their communication systems. Eventually, the introduction of the Internet and the WWW immensely transformed the telecommunications industry. This internet revolution brought about a huge change in the way businesses communicated and operated. Enterprise networks now had an increasing demand for more bandwidth as they started to embrace newer technologies. The requirements of the enterprise networks grew as the applications and services that were used in the network expanded. This stipulation for fast and high performance communication systems has now led to the emergence of converged network solutions. Enterprises across the globe are investigating new way s to implement voice, video, and data over a single network for various reasons -- to optimize network costs, to restructure their communication system, to extend next generation networking abilities, or to bridge the gap between their corporate network and the existing technological progress. To date, organizations had multiple network services to support a range of communication needs. Investing in this type of multiple communication infrastructures limits the networks ability to provide resourceful bandwidth optimization services throughout the system. Thus, as the requirements for the corporate networks to handle dynamic traffic grow day by day, the need for a more effective and efficient network arises. A converged network is the solution for enterprises aspiring to employ advanced applications and innovative services. This thesis will emphasize the importance of converging network infrastructure and prove that it leads to cost savings. It discusses the characteristics, architecture, and relevant protocols of the voice, data and video traffic over both traditional infrastructure and converged architecture. While IP-based networks present excellent quality for non-real-time data networking, the network by itself is not capable of providing reliable, quality and secure services for real-time traffic. In order for IP networks to perform reliable and timely transmission of real-time data, additional mechanisms to reduce delay, jitter and packet loss are required. Therefore, this thesis will also discuss the important mechanisms for running real-time traffic like voice and video over an IP network. Lastly, it will also provide an example of an enterprise network specification (voice, video and data), and present an in depth cost analysis of a typical network vs. a converged network to prove that converged infrastructures provide significant savings "--Purpose, leaves iv-v.

Book Synopsis Application Acceleration and WAN Optimization Fundamentals by : Ted Grevers Jr.
Download or read book Application Acceleration and WAN Optimization Fundamentals written by Ted Grevers Jr. and published by Cisco Press. This book was released on 2012-01-10 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
