NETWORK REPEATER AND ITS CONTROLLING METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To prevent the generation of a loop in a network by evading a double-master state. <P>SOLUTION: Since an operation state is switched through a back-up (master stand-by) state in the case of switching the operation state from a back-up state to a master state by an L2 switch 100, the operation state of an L2 switch 200 making a pair with the L2 switch 100 is transitionally switched to a master state after confirming that the operation state is in the back-up state. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
