It depends on the application scenario of the company's networking. Generally speaking, the special line network is mostly used in the following scenarios: 1. In the current paperless office environment, the special video conference network of enterprises can be built through MPLS VPN special line network to meet various video conference needs of enterprises. 2. To build an operation support network is to use MPLS VPN technology to realize multiple logically independent VPN private networks in a unified physical network. 3. When broadband metropolitan area network needs to serve a variety of different customers and carry a variety of different services at the same time, corresponding VPN services can be opened according to the actual situation of the network. 4. It is used for mutual isolation and mutual visits between different departments and business systems within the enterprise. If the enterprise happens to have the above needs, or the network operation of the enterprise just benefits in the above application scenarios, then it is necessary to use the special line service of Guanglian group. On the contrary, if not, you can consult the IT personnel of Guanglian group to design an optimal networking scheme. It is easy to leak corporate secrets by transmitting files between the headquarters and branches of high-tech enterprises through the Internet.

High-tech enterprises need more secure and flexible networking solutions. First, to avoid the disclosure of corporate secrets when transmitting files through the Internet; Second, high-tech enterprises have faster and more changes in data management and department design, and flexible networking schemes will be more suitable. In this case, the sd-wan networking scheme is the most appropriate, with high security and flexible networking. If the network security performance is further improved on the basis of SD Wan networking scheme, it is suggested to use the dual unit network scheme of optical network of Guanglian group, which can realize comprehensive redundant backup of the network and ensure a safe and stable packet transmission tunnel.

This is the era of 5g and sd-wan. Especially for multinationals, sd-wan is still the most popular networking solution, which helps customers combine high-quality network operators around the world to achieve the best experience, including 5g networks. Take the sd-wan solution of Guanglian group, which is widely used in enterprises, on the basis of the integration of high-quality network resources, Guanglian's solution will carry out intelligent routing and intelligent operation and maintenance, and intelligent routing can avoid network oscillation; In terms of intelligent operation and maintenance, visual cloud central control platform and 7-x 24-hour whole network monitoring mechanism can simplify operation and maintenance. Therefore, in the 5g era, with the overall improvement of network speed, sd-wan networking is to select the best among the best, which further drives the improvement of enterprise network office experience.

IPSec VPN, by definition, refers to a VPN technology that uses IPSec protocol to achieve remote access, which is an open network from desktop client to target network. While IPSec is a security standard framework defined by Internet Engineering Task Force (IETF), which provides secure communication channels for two private networks on the public network and ensures the security of the connection through encrypted channels. When in use, users can restrict access to the network by setting policies on the IPSec gateway. The IPSec VPN Technology of Guanglian group is certainly possible. Guanglian has developed in the field of network services for 17 years, and it can be said that it has rich experience. IPSec VPN is also one of its businesses. The technology has been very mature and the use is relatively stable.
