摘要
为了解决用电采集系统接口测试数据的高效传输问题,通过深入分析数据传输过程中的影响因素,提出基于资源信息的数据传输动态调整策略和基于动态规划的最优传输负载率控制策略;利用测试端获得的资源信息设计传输负载估算和可用带宽估计方法,根据传输负载率映射的效应区间选择相应的传输策略,并根据实际传输效果动态调整区间控制阈值,动态优化其传输效率;将该策略用于某省级电力公司用电信息采集统一接口平台测试系统,对比该策略和TCP Westwood算法在不同网络和数据源数量条件下的数据传输量和请求丢弃量。结果表明,采用本文中提出的数据传输请求量动态调整策略和最优传输负载率控制策略,相比TCP Westwood算法具有更好的数据传输能力和可靠性。
To solve the problem of high efficient transmission of data in the interface test system of power energy data acquire system,the dynamic adjustment strategy of data transmission based on resource information and the optimal transmission load control strategy based on dynamic programming were proposed through in-depth analysis of influence factors in the process of data transmission. The transmission load estimation and the available bandwidth estimation method were used to select the corresponding transmission strategy according to the effect interval of the transmission load rate mapping,and dynamically adjust the transmission efficiency according to the actual transmission effect. The strategy was used for a power energy data acquire and unified interface platform test system of a provincial power company. The data transmission amount and the amount of request discarding were compared between the strategy and TCP Westwood algorithm under different network conditions and the number of data sources. The experimental results show that the data transmission request dynamic adjustment strategy and the optimal transmission load rate control strategy proposed in this paper have better data transmission ability and reliability than TCP Westwood algorithm.
