METHOD FOR PROCESSING LABEL DISTRIBUTION PROTOCOL MESSAGE FOR SETTING OF AUTHENTICATED LABEL SWITCHED PATH IN MULTI-PROTOCOL LABEL SWITCHING NETWORK

摘要

PURPOSE: A method for processing label distribution protocol message for setting of authenticated label switched path in a multi-protocol label switching network is provided to set the authenticated label switched path between two terminal ends. CONSTITUTION: The method for processing label distribution protocol message includes following steps. When received message is hello message, it is determined whether security key is included within the hello message. When security key is included within the hello message, an adjacency table is formed. The received message is a label distribution protocol request/mapping message, a message authenticated code is calculated using a self password and the calculated code is compared with the code included within the received message. The calculated code is matched with the code included within the received message, the received message is decoded and the authenticated label switched path is set.
