zz from Nandita Dukkipati the author of RCP
note :RCP is a novel explicit congesion control
1. Slow additive increase means flows take a long time to acquire spare capacity
2. Unsustainable large equilibrium window; requires extremely small loss
3. Confused by lossy links -- low throughput in wireless links
4. Unfair bandwidth sharing: Flow throughput：1/RTT
5. Inefficient Slow Start
• Flows made to last multiple round trip times
• Instability -- exponential increase in aggregate traffic
6. Large queueing delay
