• The security of the algorithm is analyzed from the randomness , linear complexity of the chaotic sequence and the intensity of initial key . the results show the randomness of the key sequence pass the frequency test , sequential test , poker test , autocorrelation test , runs test , etc . and the total level is better than the binary sequence generated by the prng of delphi 7 . 0 , logistic chaotic system and rc4 , the linear complexity comes up to the expectation , the initial key has very strong intensity
  本文最后从混沌序列的随机性、线性复杂度和初始密钥的强度三个方面对算法进行了安全性分析，结果表明算法产生的密钥序列的随机性完全通过了频数检验、序列检验、扑克检验、自相关检验和游程检验等5种统计检验方法的检验，而且整体水平要好于delphi7 . 0中的伪随机数发生器、 logistic混沌系统和rc4三种方法产生的二进制序列，线性复杂度达到了数学期望值。
• Firstly , by selecting and defining the resource load indexes rationally , lbmr take into consideration the effect on the resource usage of source node and destination node by the migrant . by means of vector operations , lbmr can use multiply resources in harmony . secondly , lbmr adopts the smallest k - subset random algorithin , and the load index information is provided by the information cache
  Lbmr算法的主要思想有三点：第一，基于合理选择和定义的资源负载向量，综合考虑进程迁移对源节点和目标节点资源利用率的影响，通过向量运算协调多种资源的平衡使用；第二，基于最小k子集随机算法，采用信息cache提供的负载信息作为负载平衡算法位置策略的选择依据；第三，基于进程生命时间的概率分布，根据迁移进程减速( slowdown )数学期望值的改善程度，选择适合于迁移的进程。
