What are the parameters to provide best effort routing and QoS routing ina network?

I don't like this question. Your router should already be configured for best effort routing assuming it is configured. Best effort is simply traffic that has low priority. As to the parameters for quality of service it depends on the model of the router and whether you are using ToS or DSCP to differentiate the traffic to prioritize it. Some router vendors dynamically implement the prioritization based upon ToS field in the frame. In my opinion this question is incomplete.





Try as they might kids just aren't ready for real world computer networks. If they want to teach kids about computer networking they should stick to the basics. If they don't understand what the OSI model is and basically how it applies to computer networking then they aren't ready for more advanced topics.
