An Overview of the Principles and Functions of Asynchronous Transfer Mode (ATM).

DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c42921) has announced the addition of E-Learning Course: Principles of ATM to their offering.

"Principles of ATM" introduces the principles of the Asynchronous Transfer Mode (ATM) as employed in modern broadband networks and explains how a defined quality of service can be offered.

Course aim: This course provides an introduction to the fundamental concepts and protocols underlying data networks employing the Asynchronous Transfer Mode (ATM).

Pre-requisites: Understanding of the basic principles of packet switching and the concepts of virtual channels and the OSI Reference Model (OSIRM). It is recommended that TransNet course A - Principles of Wide Area Networks - is studied before attempting this course.

Each TransNet course:

* provides several hours of in-depth, authoritative technical training

* employs interactive simulations, hypertext links and question sessions to fully involve the trainee in the learning experience.

* provides personalised training with each trainee able to make his/her on notes and place bookmarks. A record of progress and level of achievement is recorded for each trainee.

* can be studied in isolation or as an integrated suite; each chapter of a course includes revision links to relevant subjects covered in the other TransNet courses.

Target audience: TransNet is designed for:

* Those studying for a career in telecommunications and who require a detailed knowledge of modern Wide Area Networks and data services.

* Technical staff involved in the operation, design or maintenance of Wide Area Networks.

Course Content: Introducing ATM: Overview and capabilities of ATM networks transport of multimedia traffic over existing transmission networks.

ATM cell structure: Benefits of small, fixed sized cells ATM cell structure: function of information fields in UNI and NNI cell headers.

Virtual paths and channels: Concepts of virtual path and virtual channel connections relationship between ATM virtual paths and channels and SDH transmission paths functions of ATM switches and cross-connects features of Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs).

ATM protocol layers: Physical, ATM and AAL layers of the Broadband ISDN (B-ISDN) protocol stack and their relationship to the OSI Reference Model (OSIRM) roles of the different ATM Adaptation Layer (AAL) protocols sending timing information over a Virtual Channel Connection (VCC) using the AAL 1 protocol functions of the Segmentation and Re-assembly (SAR) sub-layer and the Convergence Sub-layer (CS) of the AAL protocol.

Providing a quality of service: Role and content of a traffic contract definitions of traffic parameters including Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR) definition of quality of service (QofS) parameters including Cell Loss Ratio (CLR) and Cell Transfer Delay (CTD) features of the QofS classes.

Traffic Control: Functions of traffic shaping and policing principles and use of the "leaky bucket" algorithm concepts of the User Network Interface (UNI) and the Network Network Interface (NNI) role of the Usage Parameter Control (UPC) and Connection Admission Control (CAC) functions.

Congestion Control: Recommended methods of avoiding congestion operation and use of rate based and credit based flow control use of the Explicit Forward Congestion Indication (EFCI) methods of recovering from congestion.

Reviews:

"The advantage of the e-learning formula for the introduction training was that at the end of the e-learning courses all participants in the "advanced" module had the same level of knowledge. This was greatly appreciated by the participants" - Gino Van de Sompel, training and development consultant at Belgacom

"As a communications service provider based "off shore" we have found that the e-learning courses provide high quality and excellent content training to our engineers without the need to arrange expensive flights out of the island truly cost effective" - Bill Barker, training and development manager, Jersey Telecom

"Three factors led us to select e-learning: the courses use European jargon and bit rates, they are obviously written by telecoms professionals with real world insight and the interactions are well thought out" - Richard Downey, e-learning manager, eircom plc
