METHOD FOR PREVENTING ATTACK OF MESSAGE FLOOD AND NETWORK ELEMENT

摘要

The present invention proposes a method for preventing attack of message flood and a network element sending/receiving signaling messages to/from another network element. Said method comprises, when a number of messages for detecting transport failure are sent from a first network element to a second network element: said second network element recording arrival time of a first message for detecting transport failure as soon as said first message is received from said first network element; said second network element determining difference between the respective arrival time of said first message and a second message for detecting transport failure after said second message is subsequently received from said first network element; said second network element sending a message for shutting down transport connection to said first network element if the difference is lower than a predefined threshold; and said second network element shutting down said transport connection.
