摘要 提出一种基于趋化重采样的HBase大对象数据调度自整定控制算法,在数据接收端进行数据包接受、重组并解码,提高拆包、组包的效率,构建基于UDP协议的HBase大对象数据调度总体结构模型。定义趋化值与量化值之间的差值进行熵编码,在接收端先把数据包进行重组,得到HBase大对象数据的实时传输系统,实现数据调度自整定控制。仿真实验表明,采用了该自整定控制算法,HBase大对象数据传输的准确性和稳定性都有明显的提高,自整定控制方法能有效降低丢包数,避免延时与丢帧,能有效地对冗余信息和失稳波动信息进行整定处理。 An improved HBase large object data scheduling self-tuning control algorithm is proposed based on Chemotactic re-sampling, the data packet reception and decoding, restructuring, improve the efficiency of bag, package, construction of HBase large object data scheduling architecture model based on UDP protocol. The definition of the Chemotaxis of entropy coding and quantify difference value between, on the receiving end, the data packet to restructure, get real-time transmission system HBase large object data, data scheduling self-tuning control. Simulation results show that the HBase large object data transmission accuracy and stability are improved, the self-tuning control method can effectively decrease the number of packet loss, delay and avoid the lost frame, it can effectively realized the redundant information and instability wave information filtering and setting.
