VPN Forges a New Business Model for Power Grid Companies

 

Electric power companies have many branches, including grid companies and electric power plants distributed across one or many provinces. Many electric power plants and transformer substations are distributed in remote areas. How can we deploy and connect the business networks between head office and the branches? How can we create efficient business communications between departments? These are the essential problems the network management department of a power grid company must solve.

 

Forging Safe, Rapid, and Flexible Business Transmission Channels
Now, the head offices and branches of most power grid companies deploy networks with private lines. To ensure the transmission security of key business systems, power grid companies adopt the IPSec VPN to construct encrypted tunnels to serve as standby lines for private lines. Some companies, however, have already replaced previous private line networks with VPNs. For electric power plants and transformer substations in remote areas, the cost for LAN construction is very high. Moreover, employees often need to travel between these remote areas. So, how is the mobile officing achieved to enable them remotely access the business intranets of provincial or municipal companies? More and more power grid companies are choosing SSL VPN as the optimum solution.

 

Constructing Regional VPN
If standby private lines must be built or the business intranet connected directly through VPN, the SANGFOR IPSec VPN guarantees VPN networking efficiency in terms of security, speed and operability.

The SANGFOR IPSec VPN supports multiple encryption algorithms and allows users to add extra third-party algorithms. It also supports multiple user safety authentication methods such as USB-Keys, short messages, and dynamic tokens to guarantee the identity and permission safety of users when they access the network.

As most power grid companies construct their VPNs through Internet lines, access speeds are slow and packet loss is high. To solve these problems, the SANGFOR VPN provides unique flash-link technology to efficiently overcome delays and packet loss. In addition, the solution supports multi-lines and the dynamic compression of data packets to guarantee transmission speeds.

As many electric power plants and transformer substations are located in remote areas, they cannot be covered by optical fibers, and instead surf the net through ADSL. For this scenario, SANGFOR VPN provides unique webagent technology that supports optical fibers with fixed IPs, or ADSL with dynamic and changeable IPs. Thus, the SANGFOR VPN flexibly supports VPN networking in these branches.

 

Expanding Business Networks and Optimizing Business Processes for Power Grid Companies
Power grid companies have many small branches, and employees frequently travel between them. This requires a convenient and secure remote access solution that meets cost-efficient branch networking and mobile officing demands.

The SANGFOR SSL VPN provides the most secure remote access solution. Users can safely access the business intranets of provincial companies and HQ through multiple online authentication methods, such as username/passwords and short messages. Network managers assign different business systems and sections to different users according to permission. Therefore, authorized users can access the correct systems. The SANGFOR SSL VPN also supports third-party access by PDAs and intelligent phones to facilitate the mobile officing.

 

Boosting Access Speeds and Experience
Currently, some power grid companies need faster access speeds for their intranet business systems and on-line operations. To minimize cost, many require LAN access and mobile access for individual users based on Internet lines. Therefore, the SANGFOR provides WAN acceleration devices for VPN acceleration and mobile acceleration devices for individual users.
