Sorry, I should say more clearly.
For example, when I use ALTQ as follw,

	+-------+                      +----------------+                      +---------+
	+Server +----------+RED router(ALTQ)+-----------+Client   + 
	+-------+1000Base  +-------+--------+1000Base   +---------+
	   (ti0)          	 (ti0)                   (ti1)       	 (ti0)   
	192.168.0.1    192.168.0.2         192.168.1.2    192.168.1.1
I know that I should write to /etc/rc.conf below to configure a RED router. 
   interface ti0 bandwidth 1000M red
   interface ti1 bandwidth 1000M red
My question is that if there are two processes when packets enter  the ti0 and leave the ti0.
In other words, supposing I wish to process  incoming packets by RED and outgoing packets by WFQ  when packets go through the ti0, is that possible?
Maybe I should write a new queuing code, QQQ, which combines RED and WFQ, then write "interface ti0 bandwidth 1000M QQQ" in /etc/rc.conf ?
Thank you very much for your reply.
