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.

Network recovery is of immense and growing interest to every telecom company, Internet service provider, and medium to large enterprise that requires a high degree of network availability to carry more and more sensitive traffic (Internet, Virtual Private Network, voice traffic, etc.). Providing a working knowledge of the various network protection and restoration techniques and how they can be practically deployed is the main purpose of this book.

THE DEFINITIVE GUIDEBOOK TO NEXT GENERATION SONET/SDH, OPTICAL NETWORKS, AND NEW DATA COMMUNICATIONS PROTOCOL The next generation SONET/SDH answers the demand for a communications network with improved data QoS, higher data rates, exceptional flexibility, efficiency and scalability, superb protection, and a data-friendly standard, by integrating the simplicity and cost-efficiency of the data network with bandwidth capacity and QoS of the synchronous optical network. Designed for communication specialists who need to understand the implications and implementation requirements of the next generation optical network. Next Generation SONET/SDH: Voice and Data offers an accessible yet comprehensive introduction to this latest version of SONET/SDH. In this, his fourth book on optical networking, Dr. Kartalopoulos explains in simple terms the wealth of new protocols designed to optimize this new optical network, increase its efficiency, and decrease its cost. Featuring only essential mathematics and supported by many helpful illustrations, the text: Explains and references the new SONET/SDH standards Details the many implications and improvements that the next generation of SONET-over-DWDM will bring Provides careful explanations of such optical systems as Data-over SONET, Packet-over-SONET, Link Capacity Adjustment Scheme (LCAST), the Generalized Framing Procedure (GFP), Link Access Procedure for SDH (LAPS), Internet and Gigabit Ethernet over SONET, Virtual Concatenation, the Multi-Service Provisioning Platform (MSPP), and the Multi-Service Switching Platform (MSSP). In addition, the book explains other optical networks including the optical transport network (OTN).

Optical networks have been in commercial deployment since the early 1980s as a result of advances in optical, photonic, and material technologies. Although the initial deployment was based on silica ?ber with a single wavelength modulated at low data rates, it was quickly demonstrated that ?ber can deliver much more bandwidth than any other transmission medium, twisted pair wire, coaxial cable, or wireless. Since then, the optical network evolved to include more exciting technologies, gratings, optical ?lters, optical multiplexers, and optical ampli?ers so that today a single ?ber can transport an unprecedented aggregate data rate that exceeds Tbps, and this is not the upper limit yet. Thus, the ?ber optic network has been the network of choice, and it is expected to remain so for many generationsto come, for both synchronousand asynchronouspayloads; voice, data, video, interactive video, games, music, text, and more. In the last few years, we have also witnessed an increase in network attacks as a result of store andforwardcomputer-basednodes. These attackshave manymaliciousobjectives:harvestsomeone else’s data, impersonate another user, cause denial of service, destroy ?les, and more. As a result, a new ?eld in communicationis becomingimportant,communicationnetworksand informationse- rity. In fact, the network architect and system designer is currently challenged to include enhanced features such as intruder detection, service restoration and countermeasures, intruder avoidance, and so on. In all, the next generation optical network is intelligent and able to detect and outsmart malicious intruders.

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.
