Minor Issues

Section 1, Introduction, contains the somewhat puzzling sentence "Traffic sent by a router will use traffic flow classification information provided by the modem to identify which traffic is associated with each credit window." I would think it is the router, as opposed to the traffic, that uses the classification information. The traffic, which may originate from an upstream source, is what it is. But then the question is HOW the router should make use of the classification information. Should it e.g. set IEEE 802.1Q PCPs on particular flows to ensure that they receive preferential treatment (i.e., are throttled last in case of congestion)? In my opinion, at the very least the sentence quoted above should be rephrased; in addition some further clarification on the mechanism foreseen could be helpful.
