Two-way Transfers

• Interaction between ack and data packets

• High degree of unfairness with TCP Reno

• ACC helps reverse transfer by not congesting reverse channel buffer

• Acks-first scheduling minimizes impact of (large) data packets on acks

  • 1 KB data packet takes 280 ms for transmission
  • max. possible forward throughput is 2.9 Mbps
  • throughput achieved is 2.67 Mbps
