摘　　要：本发明涉及一种面向数据交换的云迁移优化评估方法，属于云计算和软件工程领域。该方法包括以下步骤：建立集群间面向数据交换的评估函数；向评估系统输入相关集群信息，利用评估函数和输入的信息计算出集群在本地的评估值，作为系统默认初始的最佳评估值f<Sub>best</Sub>；系统随机生成迁移集群，分别计算集群间数据交换评估量Cost和集群间网络延时评估量Mtime，并与用户设定的可接受值比较，满足条件时将Cost和Mtime归一化处理，代入评估函数计算得出评估函数值f<Sub>cloud</Sub>，并与最佳评估值f<Sub>best</Sub>比较，满足要求时将其作为最佳评估值；系统输出最佳评估值以及相对应的云迁移方案。本发明能优化企业数据交换成本，并能有效评估企业将数据迁移到云平台的可行性。

主权项：1.一种面向数据交换的云迁移优化评估方法，该方法在评估系统中运行，其特征在于包括以下步骤：(1)建立集群间面向数据交换的评估函数，其包括集群间数据交换评估量Cost和集群间网络延时评估量Mtime两部分，将两评估量通过归一化函数 $<math> <mrow> <mi>C</mi> <mo>=</mo> <mfenced open = "{" close = ""> <mtable> <mtr> <mtd> <mrow> <mfrac> <mrow> <msup> <mi>C</mi> <mrow> <mi>m</mi> <mi>a</mi> <mi>x</mi> </mrow> </msup> <mo>-</mo> <mi>C</mi> </mrow> <mrow> <msup> <mi>C</mi> <mrow> <mi>m</mi> <mi>a</mi> <mi>x</mi> </mrow> </msup> <mo>-</mo> <msup> <mi>C</mi> <mrow> <mi>m</mi> <mi>i</mi> <mi>n</mi> </mrow> </msup> </mrow> </mfrac> <mo>,</mo> </mrow> </mtd> <mtd> <mrow> <mi>i</mi> <mi>f</mi> <mi> </mi> <msup> <mi>C</mi> <mrow> <mi>m</mi> <mi>a</mi> <mi>x</mi> </mrow> </msup> <mo>-</mo> <msup> <mi>C</mi> <mrow> <mi>m</mi> <mi>i</mi> <mi>n</mi> </mrow> </msup> <mo>&NotEqual;</mo> <mn>0</mn> <mo>;</mo> </p><p class='subject'><strong>关键词：</strong>评估值 <b class='type_ico_id'></b>集群 <b class='type_ico_id'></b>评估函数 <b class='type_ico_id'></b>面向数据 <b class='type_ico_id'></b>迁移交换归一化处理分别计算集群信息可接受值满足条件评估系统企业数据软件工程输入相关 <b class='type_ico_id'></b>数据交换数据迁移随机生成 <b class='type_ico_id'></b>系统默认系统输出信息计算用户设定优化评估评估量相对应云计算云平台代入一种估量计算本地评估优化涉及网络有效建立 </p><p class='class'><strong>IPC专利分类号：</strong>H04L12/26(20060101);H04L29/08(20060101)</p>
