Abstract: A blockchain-based data processing method, device, and a computer-readable storage medium are provided. A first resource acquisition request of an object identification is transmitted for a target virtual resource to a blockchain network to make the blockchain network query a target ticket identification associated with the object identification and the target virtual resource based on the first resource acquisition request. Metadata is acquired having a binding relationship with the target ticket identification. The target ticket identification is used for characterizing that the object identification has ownership of the target virtual resource. The target virtual resource is acquired according to the metadata returned by the blockchain network. The target virtual resource is controlled to perform an interaction output in response to a triggering operation for interacting with the target virtual resource.

Abstract: A first network device receives a first data packet through an ingress port, and when a first forwarding path corresponding to the first data packet is faulty and there is no redundant path of the first forwarding path on the first network device, sends, through the ingress port of the first data packet, a first notification packet notifying that the first forwarding path is faulty. The first notification packet is generated by a data plane of the first network device, and the first notification packet is a data plane packet. Therefore, a network device that receives the first notification packet processes the first notification packet through a data plane. Then the network device can process a received data packet based on obtained fault information.
