摘　　要：在网络非终端部分对数据流的处理在传统上就面对很多问题,例如数据回环、差错包、IP分片等。而现代网络随硬件水平的提高,数据量大幅度增加亦为网络流数据处理带来的巨大的难度。除此之外数据处理还要受到了内存、CPU、I/O速度的严重限制。为了通过软件实现有效的网络数据流重组,重点研究快速正确地对IP报文分析重组。研究集中在减少内存占用,提高处理速度,减少错误率,消灭错误包带来的不稳定性。Many problems exist in processing the data stream on the network,including repeated sequence,wrong packet,IP packet fragment and so on.And nowadays,with the raising of network hardware level,the rapid increase of data on network brings great difficulty to the data processing.Also,the data processing is limited by the memory,CPU and speed of I/O.It is important to make study on IP analysis and achieve exactly and quickly the effective reverting of the data stream on network.The study focuses on the saving of memory,the growth of processing speed,the decrease of error rate and wrong packet.
