Introduction

Operating systems, networks, and protocols are all designed with a particular framework, or architecture, in mind. Although they may vary from vendor to vendor, it is this fundamental architecture that defines how all the components of a machine, operating system, and protocol fit together.

All computers in a network environment rely on network protocols to enable them to communicate with one another. Network protocols are designed and written to fit into the overall computing framework, or architecture, of the operating system running on a machine. Historically, and even today, defining how these protocols are developed is important. After operating systems such as Microsoft Windows NT began to support multiple protocols running on a machine at the same time, it became even more critical to have a clear idea of how various protocols function in relation to the operating system, and with each other.

This chapter begins with an introduction to physical network architectures. An understanding of the different types of networks is fundamental to understanding the benefits of TCP/IP, as well as many of the services provided by Microsoft, such as the Dynamic Host Configuration Protocol (DHCP) and the Windows Internet Name Service (WINS).

Without an understanding of networks in general, an appreciation of how TCP/IP works is much more difficult to reach. Therefore, this chapter briefly examines various physical network architectures before discussing the architecture of the TCP/IP protocol suite. Those readers not already familiar with physical network architectures may find this a welcome introduction, and those readers who are already familiar may find a review quickly puts points in perspective.

After a review of physical networks, the discussion turns to the Open Systems Interconnect (OSI) model, probably the most common industry architecture for defining how protocols interact with themselves and with each other. This chapter discusses the seven layers of the OSI model and the functionality of each of these layers.

After this, TCP/IP is introduced in terms of how it is managed and how it evolves through the use of Request For Comments (RFCs). It will introduce how TCP/IP maps to a four-layer model rather than a seven-layer model, while demonstrating how the functionality of each layer of the model is still maintained. Within these four layers, the reader discovers that TCP/IP is made up of more than just the TCP and IP protocols and consists of five primary protocols. This chapter serves as an introduction to these protocols as well as the Application Programming Interfaces (APIs) supported with Microsoft’s implementation of TCP/IP.
