New E-Learning Course Provides a Grounding in Frame Relay Data Services.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c42974) has announced the addition of E-Learning Course: Frame Relay A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote distances, and services are offered by most major carriers. Data Services to their offering. "Frame Relay Data Services" describes the protocols and explains the techniques used in networks offering Frame Relay services. Typical Frame Relay service offerings are also described. Course aim: This course provides an introduction to the principles, operation and features of data services conforming to the Frame Relay specifications. Pre-requisites: Understanding of the basic principles of packet switching. It is recommended that TransNet course A - Principles of Wide Area Networks - is studied before attempting this course. "Frame Relay Data Services" forms part of the TransNet series of courses. TransNet -- is a suite of interactive, multimedia e-learning courses designed to run under Windows[TM] 98, 2000 Professional or XP. -- provides training in the technical aspects of Wide Area Networks and data services. -- consists of eight separate but integrated courses: A Principles of Wide Area Networks B X25 data services C Frame Relay data services D Principles of ATM E ATM networks F IP networks G Advanced IP networks inc. voice over IP H DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary services 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. -- provides a structured assessed course and can also be used to browse for revision or reference. -- 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: Introduction to Frame Relay: Basic components of a Wide Area Network (WAN) employing Frame Relay access - introduction to the protocols involved in the provision of a Frame Relay network - significance of the virtual circuit parameters CIR (Committed Information Rate) In a frame relay network, the average transmission rate in bits per second (typically Kbps) for a virtual circuit. It defines the maximum rate that the network can handle under normal conditions. and DLCI (Data Link Connection Identifier) The number of a private or switched virtual circuit in a frame relay network. Located in the frame header, the DLCI field identifies which logical circuit the data travels over, and each DLCI has a committed information rate - facilities and benefits of a Frame Relay data service. Congestion control: Causes and effects of congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. - significance of congestion collapse - function of the fields of the frame header - explicit and implicit congestion notification - congestion control measures including the function of the DE, FECN (Forward Explicit Congestion Notification) A frame relay message that notifies the receiving device that there is a congestion problem. See BECN. and BECN (Backward Explicit Congestion Notification) A frame relay message that notifies the sending device that a congestion avoidance procedure should be initiated. See FECN. bits. Local Management Interface (LMI LMI Labor Market Information LMI Local Management Interface LMI Logistics Management Institute LMI Linear Matrix Inequality LMI Legemiddelindustriforeningen (Norway) LMI Low to Moderate Income LMI Lender's Mortgage Insurance ): The facilities provided by the link management facilities of the LMI extensions to the Frame Relay specification - implementation of global addressing with LMI - use of the Inverse Address Resolution Protocol (networking, protocol) Inverse Address Resolution Protocol - (InARP) Additions to ARP typically used for Frame Relay. Frame Relay stations route frames of a higher level protocol between LANs, across a Permanent Virtual Circuit. (InARP) in conjunction with global addressing - LMI multicasting - function of the fields in an LMI frame. Voice over Frame Relay: Introduction to the techniques used to overcome the limitations of a Frame Relay connection to provide a telephony service over a Frame Relay virtual circuit - the use and benefits of frame fragmentation, voice compression and silence suppression - use of sub-frames to transport several voice and data channels over a single Permanent Virtual Circuit See PVC. (networking) Permanent Virtual Circuit - (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down. (PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. ).
