在RMON管理信息系统库中，矩阵组存储的信息是( )。
- A.一对主机之间建立的TCP连接数
- B.一对主机之间交换的IP分组数
- C.一对主机之间交换的字节数
- D.一对主机之间出现冲突的次数
正确答案及解析
正确答案
解析
矩阵组记录子网中一对主机之间交换的字节数，信息以矩阵的形式储存。矩阵组由3个表组成。控制板的一行指明发现主机对会话的子网接口。数据表分成源到目标(SD)和目标到源(DS)两个表。如果监视器在某个接口上发现了一对主机会话，则在SD表中记录两行，每行表示一个方向的通信。DS表也包含同样的两行信息，但是索引的顺序不同。这样，管理站可以检索到一个主机向其他主机发送的信息，也可以检索到其他主机向某一个主机发送的信息。
