Abstract

The embodiment of the invention provides an authentication method of fast reroute resource reservation, a device and a system thereof. The method comprises the following steps: searching an authentication key corresponding to a router address of a receiving node in a local node; encrypting a first message according to the authentication key corresponding to the router address of the receiving node, wherein, the first message carries the router address of the local node; and sending the encrypted first message to the receiving node. The other method comprises the following steps: receiving a first message sent by a transmitting node, wherein, the first message carries the router address of the transmitting node; and searching an authentication key corresponding to the router address of thetransmitting node in a local node, and authenticating the first message according to the authentication key corresponding to the router address of the transmitting node. The embodiment of the invention realizes authentication configuration decoupling with a specific interface and prevents the same authentication information in different interface configurations in the case of multiple routes between PLR and MP.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a fast rerouting resource reservation authentication method, device and system. Background technique [0002] Multi-Protocol Label Switching (MPLS) is a technology based on label switching, which can carry any protocol data, such as IPv4 / v6, Internet packet switching protocol, asynchronous transfer mode, AppleTalk, etc., and can work in any On top of link protocols, such as Ethernet, asynchronous transfer mode, frame relay, point-to-point protocol, etc., MPLS can provide traffic engineering (Traffic Engineering; hereinafter referred to as: TE) function and quality of service (Quality of Service; hereinafter referred to as: QoS) guarantees, supports larger-scale network applications, and has good scalability. [0003] Resource Reservation Protocol (Resource ReServation Protocol; hereinafter referred to as: RSVP) is one of the MPLS label distribution protocol...
