Yue Lin · Jisuanji gongcheng yu sheji · 2007
A system engineering project with high performance and security is introduced.It has referenced value for the development and update of traffic system in existence.The project adopts MAN(metropolitan area network)technology to construct network.The security of data transmission is protected by VPN(virtual private network)technology.The system takes the J2EE platform as main platform so that it can be easily integrated and communicated with others.The design pattern combines the B/S framework and C/S fra- mework according to the characteristics of the system application modules.A typical security scheme is put forward.And from four angles there is a design for enhancing the security of the system.
