Hi i am very curious to know about sfqCodel. i guess i need to learn sfq first. So i tried with this " http://www.rdrop.com/users/paulmck/scalability/paper/sfq.2002.06.04.pdf" paper. But its so long and does not work for me. and i just want to know the concept of SFQ in simple words. So anyone please explain me about SFQ/sfqCoDel. Please tell me something.
