Introduction


This book is a rare assemblage, in that it combines the best minds across a number of topics in one central repository. Books that are authored by one or two authors limit the depth and breadth of expertise to only that particular author(s). This book draws on the breadth and depth of each author as it pertains to each topic discussed, enhancing the book's overall value. The authors of this book are Cisco Systems Optical Engineers who have more than 75 years of combined optical networking expertise.

The authors of this book have seen a need to prepare those aspiring to grow their capabilities in multiservice transport networking. The result is this book, Building Multiservice Transport Networks. This book provides the reader with information to thoroughly understand and learn the many facets of MSPP and DWDM network architectures and applications with this comprehensive handbook. This includes topics such as designing, configuring, and monitoring multiservice transport networks. A multiservice transport network consists of MSPPs and MSTPs. Cisco's ONS 15454 is an example of a Multiservice Provisioning Platform (MSPP) and a Multiservice Transport Platform (MSTP).

It is important to understand that the Cisco ONS 15454 can be considered as two different products under one product family. The ONS 15454 MSPP is one product, and the other is the ONS 15454 MSTP. MSTP describes the characteristics of the ONS 15454 when used to implement either a fixed-channel OADM or a ROADM-based DWDM network. One of the unique capabilities of the ONS 15454 is that it remains one chassis, one software base, and one set of common control cards to support both MSPP applications and MSTP applications.

Service providers today understand the need for delivering data servicesnamely, Ethernet and SAN extension. However, most are uncertain of or disagree on the most economical network foundation from which these services should actually be delivered. When placed in newer environments, service providers instinctively leverage past knowledge of network deployments and tend to force-fit new technology into old design schemes. For example, some service providers have always used point-to-point circuits to deliver services, so when customers required Ethernet services, many immediately used private-line, point-to-point circuits to deliver them. Using the ONS 15454, this book shows you how to deliver basic private-line Ethernet service and how to deliver Ethernet multipoint and aggregation services using RPR to enable newer and more efficient service models.

This book also discusses how the MSPP and MSTP fit within the overall network architecture. This is important because many service providers are trying to converge and consolidate their networks. Service providers, such as ILECs, are looking to deliver more services, more efficiently over their network. This book can serve as a handbook that network designers and planners can reference to help develop their plans for network migration.

Goals and Methods

An important goal of this book is to help you thoroughly understand all the facets of a multiservice transport network. Cisco's ONS 15454 is addressed when discussing this because it is the leading multiservice transport product today. This book provides the necessary background material to ensure that you understand the key aspects of SONET, DWDM, Ethernet, and storage networking.

This book serves as a valuable resource for network professionals engaged in the design, deployment, operation, and troubleshooting of ONS 15454 applications and services, such as TDM, SONET/SDH, DWDM, Ethernet, and SAN. By providing network diagrams, application examples, and design guidelines, this book is a valuable resource for readers who want a comprehensive book to assist in an MSPP and MSTP network deployment.

In summary, this book's goals are to

  • Provide you with an in-depth understanding on multiservice transport networks

  • Translate key topics in this book into examples of "why they matter"

  • Offer you an end-to-end guide for design, implementation, and maintenance of multiservice transport networks

  • Help you design, deploy, and troubleshoot ONS 15454 MSPP and MSTP services

  • Provide real-life examples of how to use an MSPP and an MSTP to extend SAN networks

  • Understand newer technologies such as RPR and ROADM, and how these can be deployed within an existing ONS 15454 transport architecture

  • Review SONET and DWDM fundamentals

Who Should Read This Book?

This book's primary audience is equipment technicians, network engineers, transport engineers, circuit capacity managers, and network infrastructure planners in the telecommunications industry. Those who install, test, provision, troubleshoot, or manage MSPP networks, or who aspire to do so are also candidates for this book. Additionally, data and telecom managers seeking an understanding of TDM/data product convergence should read this book.

Business development and marketing personnel within the service-provider market can also gain valuable information from this book. This book should facilitate their understanding of how to market and price new services that can be delivered over their network.

How This Book Is Organized

The book provides a comprehensive view of MSPP and MSTP networks using the Cisco ONS 15454.

Chapters 1 through 15 cover the following topics:

Part I: "Building the Foundation for Understanding MSPP Networks"

  • Chapter 1, "Market Drivers for Multiservice Provisioning Platforms" This chapter builds the case for deploying a MSPP network. This chapter focuses on key reasons why MSPPs are needed and how MSPPs can reduce capital expenditures for service providers. It also discusses another important benefit for using an MSPP: the ease of operations, administration, maintenance, and provisioning (OAMP) of an MSPP.

  • Chapter 2, "Technology Foundation for MSPP Networks" This chapter provides an overview of key technologies that must be understood to successfully deploy an MSPP network. These include fiber optics, optical transmission, SONET principles, and synchronization and timing.

  • Chapter 3, "Advanced Technologies over Multiservice Provisioning Platforms" This chapter discusses three advanced technologies supported by MSPPs: 1) storage-area networking, 2) dense wavelength-division multiplexing, and 3) Ethernet. For each technology, this chapter provides a brief history of the evolution of the service and then its integration into the MSPP platform.

Part II: "MSPP Architectures and Designing MSPP Networks"

  • Chapter 4, "Multiservice Provisioning Platform Architectures" This chapter describes various MSPP architectures. It reviews traditional network architectures and contrasts these with MSPP architectures. This comparison helps to point out the enormous benefits that MSPPs provide.

  • Chapter 5, "Multiservice Provisioning Platform Network Design" This chapter discusses how to design MSPP networks. It examines the key design components, including protection options, synchronization (timing) design, and network management. This chapter also discusses supported MSPP network topologies, such as linear, ring, and mesh configurations.

  • Chapter 6, "MSPP Network Design Example: Cisco ONS 15454" This chapter provides a realistic network design example of an MSPP network using the Cisco ONS 15454. It uses an example network demand specification to demonstrate an MSPP network design. The solution uses an ONS 15454 OC-192 ring. As part of the design, this chapter introduces the major components of the ONS 15454 system, including the common control cards, the electrical interface cards, the optical interface cards, the Ethernet interface cards, and the storage networking cards.
