This preface describes the purpose, scope, intended audience, and general organization of this Cisco IP
Videoconferencing Solution Reference Network Design Guide. It also provides information on how to
order documentation from Cisco Systems. This document provides guidelines, recommendations, and best practices to help you design an
IP videoconferencing solution for your enterprise using the Cisco Architecture for Voice, Video, and
Integrated Data (AVVID).
For the modern Web-enabled community to grow and prosper, we need to create
and deploy communication solutions that can collate an assorted collection of data
and applications, while incorporating legacy solutions still in use and allowing for
painless migration to future technologies.
For the Application Service Provider (ASP) to grow and prosper they must provide
reliable access and integration of independent information, applications, and data
stores into dynamic, interactive solutions that delight their customers....
Clearly, the Internet is changing the world. In the last ten years, since Tim Berners-Lee designed the
World Wide Web (1991) and Marc Andreesen and company developed Mosaic—née Netscape (1993)—to
display it on any PC or Mac, the Internet has gone from interesting to essential, from ancillary to
completely central. Web sites are now a required part of a business' infrastructure, and often part of one's
personal life as well. The amount of information available through the Internet has become practically
The data center is home to the computational power, storage, and applications necessary to support an enterprise business. The data center infrastructure is central to the IT architecture, from which all content is sourced or passes through. Proper planning of the data center infrastructure design is critical, and
performance, resiliency, and scalability need to be carefully considered.
This document provides design considerations and guidelines for implementing Cisco Quality of Service
within an enterprise environment.
This document is the second major update to the design guidelines and information presented in the
Cisco AVVID Network Infrastructure Enterprise Quality of Service Design Solutions Reference Network
Design (August, 2002).
This document assumes that you are already familiar with Quality of Service terms and concepts. If you
want to review any of those terms and concepts, refer to Cisco Quality of Service documentation at:...
Shrimp farming is an evolving sector of agriculture that creates important economic
opportunities in many rural communities plagued by under and unemployment. This
water farming practice relies on the wise and responsible use of coastal natural
resources and habitats. The long-term, local success of shrimp farming is also influenced
by global market forces, consumer preferences and international food safety standards.
Advances depend on accessibility of critical research, educational and laboratory services.
Cisco Data Center Infrastructure Design Guide 2.1 Release Notes. This Release Note highlights the changes in Versions 1, 2 and 2.1 of this guide, and describes the
hardware and software components that have been validated for each version.
What is Included in this DG Release?
This design guide (DG) provides guidelines for designing and building the data center switching
Table 1 lists the technologies used in the data center infrastructure design documented in version 2 of
this design guide. This table provides a quick glance of the topics and lists the timeframe (current or
future) of documentation availability for each technology.
A superstructure can be thought of as the conduit which carries a roadway over a crossing. Like any other bridge component, the superstructure is comprised of many elements. In the bridge design profession, no other component elicits so much discussion, and even downright controversy, as to the type of elements to be utilized in construction. The structural and geometric complexities of the superstructure component make it one of the most challenging design problems in a bridge engineering project....
This publication provides solution guidelines for enterprises implementing Data Centers with Cisco
devices. The intended audiences for this design guide include network architects, network managers, and
others concerned with the implementation of secure Data Center solutions, including:
• Cisco sales and support engineers
• Cisco partners
• Cisco customers
This design guide provides an overview of the Enterprise Branch Architecture, which is one component
in the overall Cisco Service-Oriented Network Architecture (SONA). SONA is a comprehensive
framework to provide guidelines to accelerate applications, business processes, and profitability. Based
on the Cisco SONA framework, the Enterprise Branch Architecture incorporates networked
infrastructure services, integrated services, and application networking services across typical branch
This book is titled ‘Airport design and operation’. However, the reader will not find chapters
devoted exclusively to airport design or airport operation. Airport design and airport operation are
closely related and influence each other. A poor design affects the airport operation and results in
increasing costs. On the other hand it is difficult to design the airport infrastructure without sound
knowledge of the airport operation. This is emphasized throughout the book.
Parr’s clear writing and lighthearted style make it a pleasure to learn the practical details of building language processors. ➤ Dan Bornstein Designer of the Dalvik VM for Android ANTLR is an exceptionally powerful and flexible tool for parsing formal languages. At Twitter, we use it exclusively for query parsing in our search engine. Our grammars are clean and concise, and the generated code is efficient and stable. This book is our go-to reference for ANTLR v4—engaging writing, clear descriptions, and practical examples all in one place.

IMS – the IP Multimedia Subsystem of the 3GPP family of telecommunication standards –
may very well be at the same time the worst and the best kept secret of the telecom world.
“Secret” because it is essentially designed to be invisible – the modern version of the infrastructure
that delivers communication to the world. “Worst kept” because it has dominated
the strategies for communication evolution in the past years, and has thus been very visible,
at least to those in the industry.
Modern WAN architectures require additional network capabilities to support current higher bandwidth
and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video
conferencing include high availability, IP multicast, and quality of service (QoS). Today, most
enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to
connect their businesses.
Both small and large enterprise campuses require a highly available and secure, intelligent network
infrastructure to support business solutions such as voice, video, wireless, and mission-critical data
applications. To provide such a reliable network infrastructure, the overall system of components that
make up the campus must minimize disruptions caused by component failures.
While the REST design philosophy has captured the imagination of web and enterprise developers alike, using this approach to develop real web services is no picnic. This cookbook includes more than 100 recipes to help you take advantage of REST, HTTP, and the infrastructure of the Web. You'll learn ways to design RESTful web services for client and server applications that meet performance, scalability, reliability, and security goals, no matter what programming language and development framework you use....
For campus networks, Cisco recommends a hierarchical network design that distributes networking
function at each layer through a layered organization. The hierarchical model enables the design of a
modular topology using “building blocks” that are scalable and allow the network to meet evolving
The hierarchical model is based on a modular design, which is easy to scale, understand, and
troubleshoot because it follows a deterministic traffic pattern. The principle advantages of the
hierarchical model are:...
