Abstract: A dynamic orchestration-based audio-video security protection method is provided. A security sharing gateway identifies a level of audio-video data in an audio-video code stream and an authority of an audio-video retrieval platform before forwarding the audio-video code stream to the audio-video retrieval platform. In a case where the security sharing gateway does not retrieve a platform authority corresponding to the level of the audio-video data, it reports alarm information to a network and data security situation awareness platform.

Abstract: A method for advertising a bit error includes that an intermediate node in a first tunnel detects that a bit error rate of a packet sent through the first tunnel exceeds a threshold; and the intermediate node sends a first packet to an egress node in the first tunnel through the first tunnel, where the first packet indicates that a bit error has occurred in the first tunnel, the first packet further instructs the egress node to send a second packet to an ingress node in the first tunnel, and the second packet indicates that the bit error has occurred in the first tunnel. The foregoing method can be used to transfer bit error information, so as to implement associated protection switching of services.

Abstract: The present invention discloses a nitrogen-sulfur co-doped Ti3C2-MXene nanosheet and a preparation method and application thereof. Ti3C2-MXene is obtained by etching ternary layered carbides of MAX phase through hydrofluoric acid; and then, the nitrogen-sulfur co-doped Ti3C2-MXene nanosheet is synthesized by a simple one-step method by taking thiourea as a heteroatom source. The nitrogen-sulfur co-doped Ti3C2-MXene nanosheet has a unique two-dimensional layered structure, large specific surface area and abundant heteroatomic catalytic activity sites so that the material presents excellent peroxidase-like activity. The method of the present invention can successfully dope two elements of nitrogen and sulfur in one step on Ti3C2-MXene, and can effectively overcome the tedious problem of a step-by-step doping step and the secondary pollution problem of different doping sources to endow peroxidase-like activity for Ti3C2-MXene.
