Abstract:
A method and a network system for negotiating a security capability between a path computation client (PCC) and a path computation element (PCE) are described. The method includes the steps as follows. The PCE sends a packet carrying security policy capability information to the PCC. After receiving the packet, the PCC acquires a security policy capability supported or required by the PCE or a security policy capability supported by both of the PCE and the PCC. In various embodiments of the present invention, negotiation of PCC-PCE and PCC-PCC may be performed by sending the packet carrying the security policy capability information, thereby greatly simplifying the security policy configuration between PCC-PCE and PCE-PCE, and simplifying the complexity in PCE deployment.
