Resource management and recursive path calculation manner and the device null which are necessary for multilevel resource transfer network path

摘要

PROBLEM TO BE SOLVED: To provide a recursive path calculating method by which even when resources required for path calculation are insufficient or not allocated beforehand at each level, low-level resources required for path requests can be automatically allocated in real-time by collectively managing resources required for calculating a data transfer path in a multi-level resource transfer network.;SOLUTION: According to the provided method, it is possible to immediately perform a network path request service at multiple levels and maximize the use efficiency of network resources.;COPYRIGHT: (C)2010,JPO&INPIT
