[Iccrg] Can TCP stay in slow start 'for ever'?

[Bob Briscoe]

Tim,

Thank you. That's exactly what I was looking for. I knew of RFC2861, 
but only remembered the restart after idle part. I hadn't realised it 
also covered non-idle but app-limited periods. The algo looks reasonable.

Yes, I would still be interested in whether anyone knows the 
implementation status of RFC2861.
