1.3. SCALABLE COMMUNICATIONS: INTEGRATED OPTICAL NETWORKS

The volume of Internet traffic has been tripling every two to four months because the Internet is growing to a worldwide scale. The various applications, such as the World Wide Web and electronic commerce, running on the Internet are turning the carrier IP and integrated optical networks that serve as the Internet backbone into a social infrastructure. These IP and integrated optical networks and their nodes must thus support higher speeds, larger capacity, and higher reliability. Various services (QoS guaranteed, virtual private networks, and multicasting) should be supported on the carrier IP. Low cost support for integrated optical networks is also welcome [3].

This section describes carrier IP and integrated optical network solutions for backbone networks, access networks, and service and operation. This part also discusses the IP network architecture of the future, an integrated optical and IP network, and its migration scenario [3].

Figure 1.2 shows a wide range of carrier network solutions, from a backbone network node to service and operation [1,4]. This section also provides an overview of the preceding solutions; they are also discussed in detail in Chapters 2 through 14 of this book.

1.3.1. The Optical Networks

It is important to provide solutions for various requirements such as integrated optical network scalability and support for various types of interfaces in an optical network. You should use a 10-Gb/s ...
