<p>PURPOSE: To realize a self-healing fault recovering method in which a recovery factor is improved as compared with a conventional method and each node has no necessity of having a large data base. CONSTITUTION: By a search phase 11, a detour candidate route and the reserve resources amount which can be applied in the route are searched and investigated and they are transmitted to a chooser. By a response phase 12, the route requesting the securing and resources amount are transmitted from the chooser to a sender. By a securing phase 13, the resources amount of the transmitted route is secured. By a confirmation phase 14, the secured route is transmitted to the sender and the route is switched to a detour route. Thus, because the search of the route and the securing of resources are separated, the securing of useless resources is eliminated. Because the route requesting the securing and resources amount are transmitted by a necessary number by the response phase 12, a path can be recovered by plural detour circuits.</p> |
