  • Method for managing virtual private network, and device
    Patent number: 11799688
    Abstract: In a method for managing a VPN, a routing device establishes a BMP session with a BMP server. The routing device allocates a VPN label associated with a VPN instance, wherein the VPN instance is used for communication between the routing device and another routing device. Then, the routing device sends, to the BMP server, a BMP message that carries the VPN label. Because the routing device sends the VPN label through the BMP message, the routing device does not need to establish a BGP peer relationship with the BMP server to send the VPN label.

  • Traffic attack protection method and system, controller, router, and storage medium
    Patent number: 10951640
    Abstract: A method for protection against cyberattack includes: establishing neighbor relationships with border routers at a plurality of traffic entrances; and receiving an attack protection request from an intrusion detection system at a first traffic entrance. The first traffic entrance is any one of the plurality of traffic entrances. The attack protection request carries a target network address that has been attacked. The method also includes: generating routing information based on the attack protection request, and sending the routing information to a first border router based on the neighbor relationships. The routing information includes the target network address and routing address information. The first border router performs, based on the routing address information, protection processing on traffic that corresponds to the target network address.
