摘要
本文阐述了IP报文标识字段比特流随机性的评价标准,通过对大量实测报文进行统计分析证明了比特流的匹配位置对随机测度值有一定影响。结果表明,标识字段比特流随机测度值随着比特流长度的增加整体上呈递减趋势。对相同长度的比特流而言,右优先比特流随机测度值普遍最高,左优先比特流随机测度值普遍最低,其它位置比特流随机测度值普遍介于两者之间。
This paper expounds the evaluation standards for bit flow randomicity of IP message identification field. By accounting and analysing a large number of messages,it is proved that the matching position effects bit flow random metric. The result of the experiment shows that with the increase of the length ,the random metric of bit flow tends to reduce gradually. In respect of the same highest, and the left priority one is universally the lowest with others between the two.
