Introduction to Cisco Network Design

Chapter Description

This chapter from Cisco Press provides an overview of the technologies available today to design networks. Discussions are divided into designing campus networks, designing WANs, utilizing remote connection design, providing integrated solutions, and determining networking requirements.


After you have determined your network requirements, you must identify and then select the specific capability that fits your computing environment. For basic information on the different types of networking devices, along with a description of a hierarchical approach to networking, refer to Chapter 2.

Chapters 2–13 of this book are technology chapters that present detailed discussions about specific implementations of large-scale networks in the following environments:

  • Large-scale Internet Protocol (IP) networks

    • Enhanced Interior Gateway Routing Protocol (IGRP) design

    • Open Shortest Path First (OSPF) design

  • IBM System Network Architecture (SNA) networks

    • Source-route bridging (SRB) design

    • Synchronous Data Link Control (SDLC) and serial tunnel (STUN), SDLC Logical Link Control type 2 (SDLLC), and Qualified Logical Link Control (QLLC) design

    • Advanced Peer-to-Peer Networking (APPN) and data-link switching (DLSw) design

  • ATM networks

  • Packet service networks

    • Frame Relay design

  • Dial-on-demand routing (DDR) networks

  • ISDN networks

In addition to these technology chapters, there are chapters on designing switched LAN networks, campus LANs, and networks for multimedia applications. The last 10 chapters of this book include case studies relating to the concepts learned in the previous chapters.
