【摘要】To meet the growing performance challenge of international thermonuclear experimental reactor (ITER) program' s global network, a WAN optimization scheme is proposed, combining high-speed protocol and improved transport mechanisms. Based on deep research for the Xpress transport protocol (XTP), made use of feature-rich interface provided by XTP, adjust the burst/rate model to avoid congestion effectively, marked sequence numbers of packet to improve go-back-n retransmission algo-rithm, also employed protocol spoofing to reduce the latency, some relevant protocol fields are analyzed to implement accurate QoS policy, and the characteristics of XTP are used for a flexible network improvement. The experimental results show that the solution can significantly improve the performance of China-France global network for ITER.%为了满足国际热核聚变实验堆(ITER)计划全球网络不断增长的性能需求,提出了一种结合高速协议和改进传输机制的广域网链路优化解决方案.通过分析和研究快速传输协议XTP,根据XTP提供的丰富功能接口,调整burst/rate模型有效避免拥塞产生,标记分组序号改进go-back-n重传机制,同时采用协议欺骗技术减少响应延迟,分析相关协议字段实施精确QoS策略,充分利用协议的特性对网络传输实现了灵活改进.测试结果表明该方案能够显著
