Nokia Quality of Service

The Nokia Quality of Service course presents and develops the theory, strategies, and techniques for implementing quality of service (QoS) strategies in an IP/MPLS network. The course introduces the key QoS performance metrics and explains the main functions of QoS needed to ensure that different traffic flows receive the treatment they require. The QoS functions of traffic classification, marking, queuing and buffer management, scheduling and rate limiting are explained in detail and are reinforced through hands-on labs that allow students to observe the impact of each QoS function. Upon completion of this course, students will gain a solid understanding of the concepts and principles of QoS, will understand the need for QoS and will learn how to implement QoS on the Nokia 7750 Service Router (SR) to achieve differentiated services.

Course Objectives

After completing the course, students should be able to:

List the business drivers for QoS
Describe traffic classification, queuing, scheduling, and marking as they pertain to QoS including, rate limiting, resource allocation and congestion management
Configure various QoS-related policies on the Nokia 7750 SR to provide differentiated services confirming to SLAs
List the criteria that can be used to classify and mark packets at service and network ingress/egress to support optimal use of networking resources
State the purpose of the queuing and scheduling parameters PIR, CIR, MBS, CBS, High Priority only, queue type, queue mode and adaptation rule
State the purpose of Weighted Random Early Detection (WRED) to increase average utilization of networking resources as they approach congestion
State the need for a multi-tiered scheduling (HQoS) architecture on SAP ingress and egress
Apply QoS concepts to the applicable service (virtual private wire service [VPWS], virtual private LAN service [VPLS], virtual private routed network [VPRN], or Internet enhanced service [IES])
Describe the need for egress port scheduling and its operation in conjunction with an HQoS scheduler
Explain how standalone policers enforce the configured rate, CIR, MBS, CBS and HPO to color packets.
Explain how Class Fair Hierarchical Policing (CFHP ) supports four layers of hierarchy, and dynamically enforces rates, using the priority, and weights assigned to child policers and arbiters.
Design, configure, apply, and predict the expected behavior of a CFHP policy.
Explain Ethernet queue groups and how they are typically used on access ingress, access egress, network ingress, and network egress.
