Module 7: Backbone networks Preview In the last two modules, you studied wired and wireless LANs and learned that the significant benefits of networking come from being able to better manage and share information. To get the greatest benefits, this sharing must occur not only within LANs, but also between them. In this module, you learn about the backbone networks that connect LANs and link them to MANs, WANs, and the Internet, thereby facilitating a greater range of information-sharing. These larger networks (MANs, WANs, and the Internet) are the focus of Module 8. Knowledge objectives z Compare and contrast the various backbone devices, including routers, bridges, and gateways. z Distinguish between the core, distribution, and access layers on which backbone network architectures rely. z Compare and contrast the common backbone network architectures. z Differentiate rack-based and chassis-based collapsed backbones from standard collapsed backbones. z Explain FDDI and ATM technologies. z Contrast ATM and switched Ethernet. Skill competencies z Label network components in a wiring closet. z Calculate the internal switching capacity of a backbone network. z Use your research skills to ensure that you keep up to date with changes as they occur. z Itemize wiring closet specifications and contents. Professional values z Defend the popularity of Ethernet in backbone networks. z Specify and justify the recommended best practices for BN and LAN combinations. z Assess strategies for improving backbone performance. Topics 7.1 Backbone network components 7.2 Backbone network architectures 7.3 Backbone technologies 7.4 Backbone design best practices 7.5 Improving backbone performance 7.6 Implications for management

7.7 Where it all comes together — the wiring closet Midterm project There is no assignment for this module, and the number of activities and text readings has been reduced. This should increase the time available for you to work on and submit the mid-term project. This case study will take you more time than required for previous assignments in this course. It will call on you to integrate the knowledge, skills, and professional values covered in Modules 1 through 7. As well, you will need to do online research and present your findings and recommendations coherently in a written report. Be sure to allow adequate time to work on the mid-term case project. Reading and resources z It is best to study this module topic-by-topic, reading the assigned text pages for a topic first, and then reading the topic itself — unless directed otherwise. z Text readings are selections from Business Data Communications and Networking , Chapter 8. z For online activities and research, you need to be running Internet Explorer with a connection to the Internet.
