| 摘 要： | 针对双窗口算法难以判断包丢弃类型的问题，提出一种新的包丢弃类型判断方法，对SCTP协议的确认块进行扩展，从确认块中获取包丢弃类型信息。在NS2上进行仿真实验，实验结果表明，改进后的SCTP协议在吞吐率方面有显著提高。

| Abstract: | Aiming at the problem that two-window algorithm can not judge the dropped packets marked type, a novel judgement method for dropped packets marked type is proposed, which extends the SACK chunk of SCTP, and the dropped packets’ marked type information is obtained from the extended SACK chunks. Simulation experiments are made in NS2, and the results indicate the improved SCTP achieves more throughput. |

| Keywords: | Stream Control Transmission Protocol(SCTP) assured services two-window algorithm throughput |
