7. Module 1: Best Practices Prior to teaching Module 1, the instructor should: Review the activities and assessments for this module. Try to include as many questions as possible to keep students engaged during classroom presentation. Topic 1.1 Ask the class, what do you think of when you hear network: Fault tolerance? Scalability? Quality of Service? Security? 7

8. Module 1: Best Practices Topic 1.2 What information do you put on an envelop when sending a letter by mail? What do you enter when calling a friend in another country? Explain how hierarchical addressing is used in postal service, telephone systems, and networks. 8

Topic Title Topic Objective Reliable Networks Describe the four basic requirements of a reliable network.  Hierarchal Network Design Explain the function at each layer of the 3-layer network design model. 10

11. 1.1 Reliable Networks 11

12. Reliable Networks Network Architecture Have you been busy working online, only to have “the internet go down”? As you know by now, the internet did not go down, and you just lost your connection to it. It is very frustrating. With so many people worldwide relying on network access to work and learn, networks must be reliable. In this context, reliability means more than your connection to the internet. This topic focuses on the four aspects of network reliability. The role of the network has changed from a data-only network to a system that enables the connections of people, devices, and information in a media-rich converged network environment. For networks to function efficiently and grow in this type of environment, the network must be built upon a standard network architecture. 12

13. Reliable Networks Network Architecture Networks support a wide range of applications and services over many different types of physical infrastructure.  There are four essential characteristics that network architects must address to meet user expectations:  Fault Tolerance  Scalability  Quality of Service (QoS)  Security 13

14. Reliable Networks Video - Fault Tolerance This video explains how a fault tolerant network operates. 14

15. Reliable Networks Fault Tolerance A fault-tolerant network allows for a quick recovery when a network failure occurs.  It provides redundancy by using multiple paths between the source and destination.  Packet switching splits traffic into packets that route over a shared network.  In the figure, the user is unaware and unaffected by the router dynamically changing the route when a link fails.  This is because it has redundant connections which allow for alternative paths if a device fails. 15

16. Reliable Networks Scalability A scalable network can be expanded quickly to support new connections without degrading the performance of services that existing users are accessing.  The figure shows how a new network adds to an existing network without degrading network performance.  16

17. Reliable Networks Quality of Service Congestion occurs when the demand for network bandwidth exceeds the amount available.  When attempts of simultaneous communications are across the network, the demand for network bandwidth can exceed its availability, creating network congestion. Quality of Service (QoS) is a primary mechanism for managing congestion and ensuring reliable content delivery to all users.  In the figure, the router has a QoS policy configured that prioritizes time-sensitive traffic (i.e., voice communications) if the network experiences congestion.  17

18. Reliable Networks Network Security Administrators must secure the physical network infrastructure and prevent unauthorized management access.  Administrators must also protect packets that transmit over the network and the information stored on network-attached devices There are three primary requirements for network security are:  Confidentiality:  Ensures that only the intended and authorized recipients can access and read data.  Integrity:  Assures users that the information does not alter in transmission from origin to destination.  Availability:  Assures users of timely and reliable access to data services for authorized users. 18
