Patent ID: 7065084

Claim:
A method for setting a label switched path (LSP) in a multiprotocol label switching system implementing a traffic engineering function, comprising: receiving a request for setting the LSP including entry indexes of a previously stored plurality of profiles; interlinking entries of a corresponding profile in accordance with the received entry indexes; setting up the LSP referring to information of linked profiles, wherein the plurality of profiles include a subscriber profile including a plurality of entries for storing forwarding equivalence class (FEC) information required for setup of the label switched path (LSP) based on the traffic engineering function, said subscriber profiles being sequentially assigned indexes corresponding to a given traffic engineering service subscriber identification (ID); a path profile including a plurality of entries for storing respective items of path information regarding a type length value (TLV) of a signal protocol required for setup of an explicit routed label switched path (ER-LSP) based on the traffic engineering function, said entries of said path profile being sequentially assigned indexes corresponding to the respective items of the path information; and a quality of service (QoS) profile including a plurality of entries for storing respective items of QoS information regarding a TLV of a signal protocol required for setup of a constraint routed label switched path (CR-LSP) based on the traffic engineering function, said entries of said QoS profile being sequentially assigned indexes corresponding to the respective items of QoS information.
