The Internet is coming to a new age where various applications have their own QoS requirements, and one size definitely does not fit all. This course introduces the concept of QoS and discusses the current limitations within the Internet. The new services requirements driving QoS in the Internet are presented. The two basic techniques used for QoS - Integrated Services and Differentiated Services - are presented. The discussion includes the benefits and limitations of the Integrated Services and the Differentiated Services approaches to QoS. While IntServ and DiffServ are the approaches, service providers need an infrastructure to deploy QoS-based applications rapidly. This course describes the policy-based QoS architecture which supports the infrastructure for delivering QoS based applications. Finally, emerging trends in IP QoS are introduced.

This course is intended for anyone seeking an overview of the IP Quality of Service architectures in the Internet.

After completing this course, the student will be able to:
• Determine the limitations of the best effort approach to QoS
• Describe the need for QoS with respect to new applications
• Explain how QoS requirements are communicated
• Define policy-based architecture
• Explain the benefits and limitations of the Integrated Services approach to QoS
• Explain the benefits and limitations of the Differentiated Services approach to QoS
• Describe the protocols that are used for each of the QoS approaches
• Identify emerging trends in IP QoS
