The network safety design of the telecom comprehensive operations management system based on VPN

TCOMS (the telecom comprehensive operations management system) is one of the support systems in operation and production of telecom-company, which not only covers wide area, but also has a complex construction and Internet connection. So, this kind of network, involving important information transportation, requires safety guarantees. In view of the importance, this paper puts forward a network safety design based on VPN (virtual private network) TCOMS. It ensures that the transporting data packet can avoid illegal interception and utilizing by outsider-staffs, and removes the hidden trouble in pivotal system data of divulging secret in long distance transmission, accordingly, the network communication safety will be ensured effectually.
