I think there are three choices * 6-tuple * 4-tuple IP/UDP (with checks against conflicting DCCP connections) * 4-tuple IP/DCCP (with checks against conflicting UDP ports at UDP decapsulation point) There have been arguments suspecting kernel implementation feasibility of 6-tuple. People have also wanted to see UDP tunneling work with unmodified DCCP implementation. If I understand correctly this would be difficult with the first two option. Would there be something wrong with the last option? I think this is the only remaining open issue (right?). So let's try to reach a conclusion. If you don't have clear favorite, is some of the options out of question? - Pasi
