Designing QoS for IP and MPLS Networks
Companies that fail to properly identify and prioritize their applications often do not operate effectively. This course will teach you how to develop network Quality of Service (QoS) designs across a variety of environments.
What you'll learn
Developing QoS designs is the first step in building an equitable IT infrastructure that gives each application the treatment it requires, based on a company's unique requirements. In this course, Designing QoS for IP and MPLS Networks, you’ll learn about the broad QoS strategies that exist for solving this complex problem. First, you’ll compare IntServ and DiffServ, and learn why only one of them is commonly deployed today. Next, you’ll discover the breadth and depth of the DiffServ toolset, including classification and marking, queuing and scheduling, and traffic conditioning. Finally, you’ll learn how to leverage those DiffServ tools to develop vendor-neutral QoS designs in campus, Internet edge, Wide Area Network (WAN), and Multi-Protocol Label Switching (MPLS) carrier environments. When you’re finished with this course, you’ll have the skills and knowledge of a QoS designer needed to analyze requirements and build architectures that network engineers can implement.
