Realize the interconnection between the new network and the original network

Network topology: 1. Overall network architecture
     The three external network access areas are clearly distinguished by the network distribution layer, and are connected to the core area of the data center together with the branch line access area and the disaster recovery network connection area. The newly built data center is mainly concentrated in the core area of the data center and six server function partitions. After completion, it is connected to the original network through the core area.
According to the business relationship, the server is divided into six areas. According to the business analysis, the business server area, the basic server area, and the management server area, the data traffic of the three areas is large, and the 10G connection is adopted; the operation and maintenance server area, the development test server area, and the training server area have less data traffic, and the Gigabit is adopted. connection. The firewall adopts transparent deployment to reduce network level and configuration, and work in active/standby mode to ensure redundancy of architecture and applications.
