H/SONET Explained in Functional Models represents a fresh approach to the modeling of transport network technologies. This practical guide and reference text uncovers the description of SDH (Synchronous Digital Hierarchy), SONET (Synchronous Optical Network) and OTN (Optical Transport Network) transport networks and equipment using functional/atomic modeling techniques. It clearly explains the use of models in the ITU-T and ETSI standards, the transport networks and the transport equipment in the definition, implementation and deployment phase. Pays particular attention to the SDH and OTN standards using functional/atomic modeling, as used and defined in the ITU-T (International Telecommunication Union) recommendations G.805 and G.809 and the ETSI (European Telecommunications Standards Institute) standards EN 300 417, as opposed to the formal language used in the ANSI (American National Standards Institute) standard T1.105. Topics of discussion range from functional modeling high level transport networks to the most detailed device functions, aided by a variety of figures and tables. Shows that functional modeling is not restricted to SDH/SONET but that is can be used to describe any transport network, connection-oriented and connectionless, e.g. Ethernet and MPLS networks. Written by a leading authority in the area, this is the first book dedicated to the novel approach of using functional modeling to describe SDH/SONET/OTN networks. This volume will appeal to manufacturers, engineers and all those involved in developing and deploying SDH, SONET, OTN, Ethernet, MPLS technology. It will be an invaluable resource for postgraduate students on network communications courses and advanced users using functional modeling.
Includes recently approved adopted and implemented standards for versatile switches, routers and multi-service provisioning platforms. Numerous illustrative examples showing actual situations or cases implemented. Covers the activities of all the major optical networking standards bodies and forums (ITU-T, IETF, MEF, and OIF).
A comprehensive guide to SDH, SONET, and OTN The ComSoc Guide to Next Generation Optical Transport provides a unique overview of SDH and OTN for engineers who are new to the field, as well as manufacturers, network operators, and graduate students who need a basic understanding of the topics. Fully up-to-date with the latest research and written by one of the foremost experts in the field, it covers: Network architectures Frames and structures Network modeling Packet transport network modeling Frequency justification Protection mechanisms Mapping methodologies Concatenation SDH and SONET overhead processing The book is complemented with 200 illustrations that explain key concepts in an easy-to-understand format, while references point readers to the appropriate standards documents for further reading. Whether you're new to the field or just need a basic understanding of SDH, this is a must-have guide.
Since the turn of the twentieth century, telecommunications has shifted from traditional voice transport to data transport, although digitized voice is still a large contributor. Instead of an evolution of existing transport standards, a revolution was necessary in order to enable additional data-related transport. Next Generation SDH/SONET provides a detailed description of the enablers of efficient data transport over any synchronous network. These include virtual concatenation (VCAT), the operation to provide more granularity, and the link capacity adjustment scheme (LCAS), an extension of VCAT that provides more flexibility. Equally, generic framing procedure (GFP), the methodology that efficiently transports asynchronous, or variable bit-rate data signals over a synchronous or constant bit-rate, is explored in detail. Describes new extensions to SDH/SONET standards to provide more granularity and flexibility in their structures, enabling the efficient transport of data-related signals such as Ethernet and FICON Presents comprehensive sections on the implementation of multi-service transport platforms (MSTP) enabled by VCAT, LCAS and GFP Provides valuable advice on how to exploit existing networks to create or extend LANs towards metro (MAN) or wide (WAN) area networks and also to support storage area (SAN) networks This volume will appeal to manufacturers, engineers and all those involved in developing and deploying SDH, SONET and OTN technology. It will also be an invaluable resource for postgraduate students on network communications courses.
Comprehensive reference to successful service design for the telecommunications industry Telecommunications companies operate in increasingly competitive environments. The companies that survive and excel are those offering the most compelling range of products and services. These services are complex since they touch all aspects of business. Service design and implementation skills are therefore the key for staying on top of the competition. Successful Service Design for Telecommunications provides a comprehensive guide into service design and implementation. The author provides a consistent approach to designing scalable and operable processes that can be used when designing a variety of technologically based services; offering concepts, principles and numerous examples that the readers can easily adapt to their technological environment. Key features: Defines what telecommunications services are from business, technical and operational perspectives Explains how telecommunications services can be implemented, including implementation strategies for both new service introductions and enhancements to existing services The principles and management processes described can be used on all telecommunications services (fixed, mobile, broadband and wireless) and technology (e.g. IT and Internet) based services Includes references to the current best practices and industry standards and complements the eTom and the OSS/ BSS models proposed by the TeleManagement Forum Features numerous real-life scenarios and examples to support the discussion on the key concepts of service design This book will be of interest to managers, service designers, project managers, IT professionals, operation managers and senior executives who work in the telecommunications sector. University students studying telecommunications, IT and service science courses will also find this text insightful.
This book presents the practical motivation, theoretical description, and extant techniques for traffic grooming in optical networks. The description of the various topics of research will be authored by leading researchers in this area, and will contain comprehensive description of related literature for each area. This book is intended to be a definitive reference and text for traffic grooming both for the practitioner in industry and the student in academia.
Service level agreements guaranteeing quality of service have helped your organization to keep old customers and win new ones over. Although it may be easy for the sales department to ink a service level agreement, you have to handle the constant problems of phase fluctuations, jitter, and wander, that threaten the quality of service spelled out in these service level agreements.
This volume constitutes the proceedings of the Second International Conference on Intelligence in Broadband Services and Networks (IS&N '94), held in Aachen, Germany in September 1994. The book addresses the design of telecommunication services in the rapidly changing technological and regulatory environment. The 47 revised papers presented in the volume reflect work done under the CEC RACE project "Intelligence in Services and Networks" as well as individual research done independently. The volume is organized in 11 chapters, all introduced by surveys by the session chairpersons. Among the topics covered are: the context of IS&N, user interfaces, component models and service creation, TMN implementation, service management, and beyond IN.
"Explanations of the technologies are provided within the concepts of architecture and layering models, multiplexing and switching methods, routing algorithms and protocols, network control, traffic management methods, and QoS support. The book also offers one of the first overviews of the IP over WDM field."--Cover.
