VPN management center should be a graphical interface based on GUI technology, encryption, access, traffic information, access to users, network access and intrusion and alarm should be clear. Because VPN is a large integrated network concept, when there is a single point of failure or accident, should be central in the management of an intuitive way to display and alarm, and automatically start the backup equipment or lines, reconstruction of VPN network access, the system a very good redundancy. Besides, the system should be considered in the design configuration of the convenience, security domain-based security policies and user roles and security rules established way. Because the traditional IP address based on user identity and a way to develop security policies, while in a VPN network, application, would be extremely complicated, if not impossible to operate, while role-based security domain security policies and users to develop ways to use the logical way expression system safety requirements, greatly simplifying management, reducing the burden on system administrators, and a great overall strategy to ensure the consistency of the system, reducing the development of security policies and rules of the possibility of error.
Analysis is mainly due to integration of the core 7150 MCP73 MCP68 frequency higher than the 7050, performance is somewhat better; course, PE2140 native AM2 X2 Duo Core construct more advanced than some also a factor. 4 onboard DDR2 slots support up to 8G of DDR2 533/667/800 memory frequency, enhanced memory, the same power supply system to ensure stability when overclocking memory, the memory slots still distinguish between orange and light green two-channel mode, open the dual-channel is also very convenient. In terms of expansion slots, the motherboard provides a PCIEx16, 1 Tiao PCIEx1, plus two PCI slots, a solid power supply, to ensure that both the graphics card or other expansion card can be stable operation, this design can meet all kinds of the users requirements, Biostar TF7050-M2 motherboard disk integrated bridge with a strong performance, support 4 speed 3.0G / S of SATAII interface, and supports RAID, disk performance is quite amazing, also for the convenience of the old customers, old Upgrading the machine also supported an IDE and an FDD, shows the human side of Biostar.
