One.Needs analysis
With economic development, chain business model more and more enterprises, such enterprises most of the business is to provide services directly to customers, can provide accurate, fast and comprehensive service to become an important logistics competitiveness of enterprises.
Many chains to improve their service capabilities, use of information technology within the enterprise to build a variety of information platforms (such as distribution, distribution systems, etc.), to achieve the integration of business data.But the industry business model determines the existence of a large number of branches, which branches to the headquarters of the urgent need to access the LAN data exchange, and information systems synchronization.If the use of DDN special line is too expensive to implement, for profit for the period of the chains can not afford, while the cost of using the same dial-up Modem is not low, and also mainly the security and performance.
As VPN technology matures, the use of VPN way to achieve data transmission is becoming a high-efficiency, low cost, high-security connection, more and more chains are used.
II.Status of the corporate network
Corporate headquarters and distribution center / store not in the same area, each branch or chain through the ADSL / ISDN / Modem, etc. access Internet.Headquarters for the database center, the branch or chain on a regular basis to business data and other information sent by fax or telephone to headquarters, headquarters and then to check the entry.Ineffectiveness, the error probability is relatively high.Another part of the company using the Internet chat tool and security were not guaranteed Email communication links, with great risk.If there is loss of data, loss unknown.
III.Solutions
ADSL Internet access can use the company's headquarters, and the installation XPO VPN Server Edition, branch offices and mobile users can use ADSL, ISDN or modem Internet access, were installed XPO VPN gateways and XPO VPN client software.Created by XPO VPN secure tunnel.Branch offices and mobile users can access safe and convenient to the corporate headquarters network.
Specific method is as follows:
IV.Features:
? Secure VPN system
Xun Bo XPO VPN using the following measures to ensure the safety of the system user VPN,
? All XPO VPN tunnel to pass through the data is encrypted after AES/3DES 128-168 bit encryption algorithm, can effectively prevent data being intercepted or tampered with.
? Strict key authentication, only users who know the key can access, to prevent unauthorized users into the key for safekeeping by the company network can change at any time.
? INAS digital certificate technology to support PKI certification system, binding the user's computer hardware VPN information (hard disk, CPU, NIC, etc.), only the user name and key, the user digital certificate through a comprehensive certification to get through, even if the user name and password arestolen, VPN network is still unbreakable.
? Strong in network management functions, offices connected via VPN to the headquarters LAN, the administrator can assign access to the headquarters of resources within the network, different branches can set different access rights, to prevent people using the network formalicious attacks, effectively guaranteeing the security of the network.
? Fast
XPO-VPN uses kernel drivers technology and real-time data stream compression algorithm (LZO), can make up to 90% bandwidth utilization, especially for database, file transfer applications.File transfer process, the maximum compression ratio of up to 180%.
? Highly efficient and stable VPN system
XPO-VPN to support full dynamic IP address network, while supporting a variety of access methods, such as ADSL / PSTN / IP / GPRS / WLAN, etc., so the legitimacy of user access, IP addressing was particularly important for the legitimacyAt present the majority of VPN products similar to DDNS (Dynamic Domain Name Service) technology addressing user access, such as DDNS, WEB scripts, addressing, and authentication of these hosting services are often used, the use of scripts, virtual hostsStability is difficult to be assured by the scripting authentication technology also limits the information difficult to achieve high strength encryption.In response, his company has developed fast iNAS (intelligent network authentication service) technology, UNIX server implementations and hardware certificate technology, can guarantee the legitimacy of user access, VPN addressing the stability of the truly exclusive (private) of theinternal network.
Bo Xun's iNAS other servers are hosted in Chengdu, Beijing, Qingdao, Shenzhen Four telecommunications room, a carrier-class stability, and the 10 is an inter-cluster multiple servers, mutual backup, if one server fails, XPO VPN will automatically switch to another server address, authentication, does not require human intervention to ensure the stable operation of the VPN system.
Five.Implementation Effect
Bo using VPN as a solution fast, the sub-site VPN tunnels can be accessed through direct connection Bo Xun based database management systems, real-time data entry for sales.Distribution center can be connected at any time, using a variety of materials management system mobilization and distribution.The main suppliers or customers can also license the corresponding VPN access through the rapid to the corporate headquarters of Bo on the application server, direct delivery of data transmission, thereby improving the efficiency of procurement and supply.
