Huocheng County Vocational Education Center is a comprehensive vocational school integrating vocational education, technical education and vocational training. It provides a large number of middle and intermediate technical talents for the society every year. Campus network is an important infrastructure for school’s informatized application. In recent years, with the continuous expansion of school scale and the continuous deepening of informatized applications, the current campus network cannot meet the increasingly complex business demands in terms of availability, controllability and maintainability. It’s urgent to build a brand-new campus network with stronger performance, higher reliability, better security, easier management and maintenance, and more suitable for its informatized demands on business applications.

The whole scheme adopts a modular architecture, which divides campus network into network core area, teaching access area and office access area. The network core ensures reliable and efficient data exchange, while the core enables routing protocols as a Layer 3 gateway. The teaching, office and living access area are mainly responsible for regional high-speed access. The private network area is mainly deployed with finance-related all-purpose card and other applications. The network exit area is responsible for ensuring the security of the entire campus network, distinguishing and controlling different traffic types, ensuring the effective use of bandwidth, and deploying online behavior audit logs to meet the security requirements of national laws and regulations.
