Product features
QoS
Introduction to Quality of Service (QoS) as the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of data performance. Descriptions of the traffic classification, prioritization, queuing and bandwidth management mechanisms and protocols. What are the most QoS sensitive applications and what are the parameters that affect their efficiency. Designing methods of end-toend QoS policies .Classification and marking
Presentation and practice on the most popular, standard marking-prioritization mechanisms of Layer 2 (IEEE 802.1p / VLAN tag priority) and Layer 3 (DiffSev / DSCP in ToS field) levels. How these mechanisms inform the switches which Class-of-Service (CoS) queue should be used. Introduction, analysis and hands on practice on the traffic classification mechanisms like classifiers/access lists.Scheduling and queuing
Introduction to the scheduling processes that determine the order in which queues are serviced. Details of the queuing mechanisms and how they enable the switch to differentiate the treatment of different traffic types. Analysis of the strict priority and Weighted Round Robin (WRR) queuing methods.Policing and shaping
Presentation and practice on the process of reducing a stream of data to a predetermined rate or level. Explanation of bandwidth limiting mechanisms for single and twin rate three color metering and how the RED curve queue management algorithm helps in the arrangement of accessing the egress queues.Key selling points
- QoS
- Classification and marking
