No. It is a cable provider. Actually, I suspect that there is some shaping. But from what I see at the server side dump, the transmission window does not get larger during about 300 packets (and 70 or so acks) without any drop or retransmission (that the server would know of). Even in congestion avoidance mode the sending window should get larger with time (with the advertised 64k receive window). Thx for the help...
