In the Strategy, we will send some special interest and data packets to exchange control information. Therefore, we want to control the priority of interest and data packets in NFD to process the control packets first. Specifically, I want to build two queues in NFD, one for control packets and one for common packets and the program will always process the control packet queue first until it's empty. However, I don't know how to implement this. I think there is congestion control in NFD, which probably needs to prioritize packets too, am I right? If you are experienced in this, could you please tell us how to do the packets priority?</div><div style="font-size:1rem;color:rgb(49,49,49);word-spacing:1px" dir="auto">Best regards.</div><div style="font-size:1rem;color:rgb(49,49,49);word-spacing:1px" dir="auto">Yuanhao Wu</div>
