What I don't understand is why this information is useful: REMB performs the exact same computation as TWCC, but it does it on the receiver side, and only sends the result to the sender, thus avoiding the chattiness but yielding the exact same result. What am I missing? What exactly does TWCC buy you? -- Juliusz
