There are two possible interpretations for the term "current rate". If you mean the one declared, then I think Stef is correct. That is, you can declare class B to have rate 125k which is .25 that of class A, but if you then change class A to 1000, class B is still 125, no longer .25 class A. However, you more likely mean that the bandwidth actually used for class B at any time should be .25 that of class A. And this is the default behavior if you just declare the class B rate to be 125. That is, excess bandwidth is shared in proportion to the requested rates. Just put A and B below a common parent (perhaps with a ceil of 3000k).
