In a book that I'm reading, it gives examples of marking traffic. One of the examples is:
Interactive video AF41 (CoS value 4)
Streaming video CS4 (CoS value 4)
I thought AF and CS were not "better than each other." In other words, I thought they were the same, but it depended on what you did with that class was what mattered. Is that the case, and this book is just showing that AF and CS values can be used, or is there more meaning to this that I'm missing?
