Sinfor Expressway Remote Networking Construction Basic Solution

The expressway has already occupied the leading position in the short distance transportation field in our country, the establishment high efficient highway network between each big city has already become the consensus. Long Highway Network division of many highway management stations, in order to survey the use of highways, charging the past costs of highways, the daily report of the information are very much. But because of the remote location of these management stations, many of the line can not be pulled, if the cost of laying their own fiber will be extremely expensive, so this problem has been plagued the highway managers.

In recent years, with the popularization of Iinternet, VPN can make use of public network resources to establish a safe, reliable, economical and efficient transmission link, which has aroused people's extensive attention. With the support of VPN technology, the expressway management station located in any area needs to be integrated into the local Internet separately, and can form an efficient and unified virtual private network. Deeply convinced that the technology provided by the Sinfor Dlan VPN solution on the basis of the traditional VPN technology, aiming at the lack of domestic fixed IP, the numerous Internet access methods, the uneven operation of IT skills and other factors of the technical and product innovation, for the expressway industry provides a high security , high-performance, high stability of the VPN solution.

To a Guangdong Expressway Management Center, for example, the center of many management sites, in the Highway Management Center using Information management tools, management of expressway operation and maintenance, all the highway management stations need to network with the center, the management station maintenance work into the management system. However, the traditional way of Internet connection can not be pulled at the location of the management office, the modem pool solution, the number of access is small, and the speed can not meet the management system needs. So it's a good solution to consider using VPN as a combination. In many VPNs, the Highway Management Center adopted the conviction of Sinfor Dlan products.

Implementation effect:

It realizes the interconnection between the management station and the center, supports the existing Internet access modes, and provides a solid guarantee for all the management stations to realize interconnection.

With hardware bundled encryption technology and AES transmission data encryption, sufficient to ensure access and transmission security

Through data stream compression technology, the bandwidth utilization ratio of single network is achieved on average up to 130%, and the multiplexing technology is provided to guarantee the bandwidth required by the management system.

To realize the remote maintenance requirement of the center maintenance personnel as a professional VPN provider, Sinfor Dlan VPN scheme provides a high security, high performance and high Maintenance interconnection scheme for the expressway industry, with several important features as follows:

High Security VPN

Due to the use of the Internet as the basis for connection links, deeply convinced that Sinfor Dlan VPN products combined with a variety of security technologies, in the tunnel encryption, access to user authentication, access to user rights control to provide users with comprehensive security.

Tunnel encryption: The use of international advanced AES 128-bit encryption technology to encrypt tunnels to prevent data theft and interception. Advanced encryption technology to ensure high encryption level while providing a strong performance assurance, effectively enhance the tunnel transmission efficiency.

Access user authentication: In addition to RADIUS authentication based on user accounts, sinfor Dlan Innovative use of patented technology-based on hardware identity system, the user account and its computer hardware information binding, even if the user account accidentally leaked, Illegal user access is not possible because illegal users cannot use the computer that was previously bound to this account. For remote mobile office staff, due to the possibility of theft or illegal use of the computer, the technology also uses the hardware USB key authentication mechanism for mobile users, using the unique ID number of Dkey USB portable device as its license to use VPN, It makes it possible for the designated personnel to access the designated resources using the designated account number and the designated computer, which greatly improves the overall security of the VPN.

Access to User Rights control: ordinary VPN products in the user access to arbitrary access to the local area network resources, for the security requirements of higher units, this unrestricted access to create great security risks, sinfor Dlan eliminates these security risks by setting more detailed service access rights in the VPN system. Sinfor Dlan can set different access permissions for each user, such as some users can only visit the headquarters of the OA system, can not access the financial system, and so on, different VPN users can set the access to different resources, to avoid the VPN user due to excessive permissions caused by security risks.

High Performance VPN

Efficient transmission efficiency: efficient encryption and decryption algorithm and powerful "streaming compression" technology makes the Sinfor Dlan VPN to the actual bandwidth utilization of up to 130%, in the transmission of Word, BMP and other documents and SQL query performance especially outstanding, far beyond the general VPN products digestibility Transmission efficiency.

Redundant capacity design: Telecommunications networks are often paralyzed by the peak of traffic, as well as data networks, which can be paralyzed if the capacity of a network device cannot carry a sudden increase in business load. The design capacity of sinfor Dlan is much larger than the actual capacity of the average user, which achieves a gateway to support 5,000 network users, 1024 VPN tunnels, 80M VPN tunnel bandwidth, this redundancy capacity design ensures that the VPN network can run stably even if it encounters a sudden peak of business.

Powerful routing function: Sinfor Dlan with intelligent soft routing, it can route non interconnected data (that is, direct access to Internet data) to other gateways or routing devices in the local area network, so as to separate the internal and external network data and expand the export bandwidth; or use multiple lines, A cluster of multiple gateways simultaneously accesses numerous branches.

Easy to maintain VPN

Simple and easy to configure backup and restore: Sinfor Dlan saves configuration information in multiple encrypted configuration files. The system provides a packaged backup function for all configurations, and the administrator can easily back up and restore the configuration files. The administrator can also configure the remote network locally, using the configuration Recovery feature to import the configuration remotely.

Support for remote deployment and module upgrades: sinfor Dlan for pure software products, easy to install, remote installation can be achieved, remote deployment. At the same time can also remotely control the computer, without each management station are equipped with professional network administrator, saving a lot of human resources.

Shenzhen Expressway

Shenzhen Expressway Co., Ltd. is the only authorized by the Shenzhen Municipal Highway franchise company, the company operates in Shenzhen Expressway and National Road has formed a complete road network. Company for the stock exchange of Hong Kong (H shares) and Shanghai Stock Exchange (a) listed companies.

Shenzhen Expressway Co., Ltd. Headquarters information level is high, using a variety of software systems as the company's calendar operation and business processing platform. But the subordinate company is limited by the network condition, has not been able to share the resources with the headquarters, constitutes the unified information platform. Before each subsidiary to log in to the headquarters of the network, only on the designated computer through the remote modem dial-up mode of access, high cost, slow speed, and the use of inconvenience.

The use of SINFOR network Netcom Remote network interconnection platform, the various subsidiaries at the same time using ADSL access to the Internet, the whole network real-time access to the headquarters, sharing the headquarters of the software application system, as in the same LAN.

Guang-Shen Pearl Expressway

Canton-Shenzhen-Zhuhai Expressway Co., Ltd. is a highway construction company in Guangdong Province and Hong Kong and China Development (Expressway) Co., Ltd. jointly holding, is responsible for the construction and management of the Pearl River Delta Pearl Highway.
