This is Selvajegan here .Have a very good understanding of networking Fundamentals

This topic will cover all QoS Mechanisms like Classification ,Marking, Queuing , Congestion Avoidance ,RED ,WRED including Quality Of Service Lab Scenarios for a better and detailed understanding of Quality Of Service

will cover all the Layer 2 and Layer 3 Quality of Service Markings which is used for traffic prioritization

Layer 2 Marking done at the frame level and Layer 3 Marking done at the packet level

Will understand the concepts of shaping and policing. Shaping done at the customer end which is used for buffering traffic to a certain bit rate and policing done at the provider end

This section i have categorized into two sections

One about QoS Theory which gives an overview about QoS , Queuing , Policing and Shaping Technologies

Second section is about Complete QoS Lab Exercises which will give a detailed understanding about Layer 2 and Layer 3 Marking

Configuration of Layer 2 Marking for Switches

Configuration of Layer 3 Marking for Routers and Switches

How to Configure Shaping and Policing for Customer and Provider end

How to Shape traffic up to the Excess Burst

and about the Policing categories like Policing Single Rate Two Color , Policing Single Rate Three Color and

Policing Dual Rate Three Color and how to configure all these three categories
