As I remember (I haven't read the papers in some months), the Vegas
implementation adds the use of detecting RTT increase to detect incipient
congestion and to back off in that case in an effort to avoid loss, but when
actual loss occurs, the rate is still dropped as per TCP Reno.

My comments about UDP-based protocols interoperating well with TCP is based
on the fact that most TCP implementations are Reno- or newReno-like.
