Hi,

I would add the end systems here: "This information is currently only visible 
at the transport layer in the end systems."

Maybe change the order here: "Tools that exploit the CONEX output could be 
used for simplifying differentiation of quality of service (QoS); policing 
compliance to congestion control; mitigating distributed denial of service 
(DDoS); and so on."
