Hi all,
I've always struggled with understanding and applying the correct QoS
solution to a particular problem. I'm working hard at understanding
when and where different solutions are appropriate. As with other
topics, I think I understand the theory, but need to understand the
real-world application properly.
While working through MQC, I couldn't help wondering about how
important ip precedence values are in the real world and, in
particular, the Internet. On private networks, I can see the value in
setting the ip precedence value, and providing levels of service using
these values.
When sending traffic onto the Internet, is there any value in setting
precedence values? Would ISPs rewrite these values as standard? Even
if ISPs don't explicitly use precedence values, wouldn't it be
beneficial where QoS devices like WRED and WFQ are employed, as these
can use the precedence value?
Thanks again,
Roy
