Next Generation Networks: Current Developments and Emerging Trends


Next Generation Networks: Current Developments and Emerging Trends provides comprehensive instruction in the design and implementation of state-of-the-art data networks. This intensive five day course program is designed to present engineering and IT professionals with clear insight into the way the essential features of networking are being redefined and how traditional approaches are being replaced with innovative new technologies. The principal emphasis in this course is on the technologies that are embedded in the three lower layers of the OSI reference model – the infrastructure technologies of the industry.

The telecommunications and computer networks industry has undergone remarkable changes over the last several years. For some time, innovation and investment were stifled by the economic downturn, but as this industry sector recovers, there are now important opportunities to be pursued.

The IP-based infobahn has become a reality. Everyone with a career commitment to technologies affected by these events is faced with challenging developments that are revolutionizing this industry. This course presents an imaginative, forward-looking engineering-level perspective on emerging network technologies, and maps this fascinating and dynamically changing landscape.

Delegates will be guided through a systematic development and applications of emerging technologies that are defining the global infobahn; broadband infrastructure, wireless innovations, network routing and switching, high speed LAN/MAN systems, the Internet Architecture, and mobile computing applications.

Course Objectives

The objective of this course is to present the technical features, applications and design considerations of new and emerging network technologies -- and develop a comfortable, practical understanding of how each technology is best applied.

Specific, technical objectives include developing for each delegate:

• A working knowledge of emerging network technologies, how they are used, what their advantages/disadvantages are, and what their future offers.
• A comfortable understanding of applicable terminology, which is critical to a successful learning experience.
• An appreciation that appropriate network performance is always the result of deliberate, continuing management and reengineering efforts -- never a one-time design initiative.
• A understanding of the process of evaluating technologies with a view to judging their suitability for specific purposes, and recognizing associated risks.

Who Should Attend

This intensive short course is designed to appeal to:

• Network engineers and designers who have responsibility for keeping networks current
• IT professionals who respect the fact that networks are an increasingly vital segment of the IT world
• Technical managers who are committed to defining a networks vision for their enterprise
• Specialists in related disciplines who need an effective understanding of how developments in this field will impact their work

Course Material and Program Features

Each delegate will be provided with a permanent, comprehensive workbook that is much more than a set of lecture notes. In addition to being a workbook that tracks with the lecture portion of the program, it is designed with features that give it real value as a permanent reference resource.

These include:

  • A descriptive text format, designed to be a highly readable, valuable reference on the job.
  • A text-book style Subject Index and a comprehensive Table of Contents, consistent with enabling effective reference access to content details.
  • A thorough, highly readable subject-specific glossary that provides detailed descriptive treatment of key items of terminology.

This course is presented as a workshop program with a series of network design activities. Delegates will have opportunity to develop design concepts and interact with others in preparing designs and plans to support state-of-the-art enterprise network applications.

Delegates are invited to be bring descriptions of their own network configurations, so that issues and technologies developed in the program can be directly related to their work circumstances.
