OPERATING METHOD OF PATH COMPUTATION ELEMENT FOR AVOIDING DELAY OF PATH COMPUTATION AND OVERLOAD

摘要

According to an embodiment of the present invention, an operation method of a path computation element comprises the following steps: when a path computation request message is received, determining whether an estimation time consumed to process and complete the received path computation request message exceeds a predetermined overload transition time or not; generating an overload state object message to notify the same in a state of being overloaded according to a determination result; and broadcasting the generated overload state object message to a plurality of path computation clients connected through a network.
