This application discloses an AAA high-concurrency authentication method and system. The method is introduced into the Netty server, and the authentication information sent by the terminal device is forwarded to the AAA authentication server through Netty. The authentication module is based on the authentication information and the historical authentication information in the Redis cache. Authenticating the terminal device; and updating the historical authentication information in the Redis cache. Netty's IO thread NioEventLoop can process hundreds or thousands of client Channels concurrently due to the aggregation of the multiplexer Selector. Since the read and write operations are non-blocking, this can fully improve the operating efficiency of the IO thread and avoid due to The thread suspension caused by frequent IO blocking does not need to waste CPU resources for switching between threads, and can solve the technical problem of network packet loss in the existing AAA authentication technology. In addition, Redis caches information to reduce disk IO and improve authentication efficiency.
