This paper studies the application of binding model algorithm in BGP anomaly detection and designs two methods to detect anomalies, gradient boosting decision tree combined linear regression and gradient boosting decision tree combined hidden factor decomposition. This article introduces Cache 5G multimedia technology and introduces a new type of Cache 5G multimedia technology: NCLMBCN. The relay transmission system is the NCLM BCN solution, which uses cache 5G multimedia with users and repeaters to eliminate interference caused by relay transmission, thereby improving the reliability of user reception. This article takes the daily teaching management work of the Vocational Education College as the background to research, design and develop an online teaching management system based on PHP and B/S mode, which is essential for the school's daily teaching management to implement school automation and network. Then, through a comparative study of the vocational education administrative management system of similar schools, the system demand analysis was completed. Then provide the detailed design of the entire system according to the following requirements, including the design of each functional module and database design. This article mainly introduces BGP anomaly detection and 5G multimedia technology into the vocational education management system, so that the education system will continue to develop and progress.
