| 摘要: |
| 在区分服务(DiffServ)中使用确保转发(Assured Forwarding)进行TCP传输，存在带宽分配不公平问题。已有的工作没有综合考虑订购带宽、报文大小、RTT(Round Trip Time)对TCP性能的影响。为了解决TCP在DiffServ中的公平性问题，提出了面向区分服务的拥塞控制算法DSOCC (DiffServ-Oriented Congestion Control)。通过模拟验证了该算法的有效性。 |

| Abstract: |
| When using DiffServ AF to transfer TCP traffic, the bandwidth is not allocated in a fair way the previous work does not consider the three factors affecting TCP's throughput all together: subscribed bandwidth, packet size and RTT. The paper proposes DiffServ-Oriented Congestion Control (DSOCC) to resolve the problem on TCP fairness. The validity of the algorithm is verified using ns-2 simulations. |
| Keywords: DiffServ AF TCP bandwidth allocation fairness |
