MPLS VPN is one of the most mature, stable and comprehensive networking schemes in China at present. As a "senior player" in the field of networking, the MPLS VPN networking scheme of Guanglian group is also very advantageous. For example, one stop service, the MPLS VPN networking scheme of optical union follows the project management and ISO standards of international standards from project proposal, start, plan, implementation and completion. Among them, in the selection and acceptance of backbone lines, the technical team of Guanglian group has investigated for no less than two weeks, and there are no less than three candidate suppliers. Introducing the backbone line replacement system and eliminating substandard lines may be the most stringent line acceptance standard in the industry. Now, Guanglian group has very obvious advantages in MPLS VPN networking and sd-wan networking.

VPN is a virtual network built on a public network, which can provide a secure communication channel for the transmission of data and IP information in the internal network. SEC VPN is a VPN Technology Based on a relatively complete and systematic VPN technology, which uses sec protocol to achieve remote access. Based on IPSec VPN technology, Guanglian group has monitored the main and standby lines for customers for 7 x 24 hours, improved the availability of resources, and achieved a safer, more stable and more convenient management experience.

MPLS VPN is a mature and widely used networking solution. However, since the sd-wan networking scheme is becoming more and more mature, many enterprises prefer to use sd-wan. The reason is that compared with the traditional MPLS VPN networking scheme, sd-wan breaks the data black box, enables the enterprise IT department to achieve visual management, and has very obvious advantages in network flexibility, expansibility and cost. Therefore, sd-wan networking scheme is recommended. At present, the sd-wan networking scheme is that the landing service of Guanglian group is relatively comprehensive, and the operation and maintenance is relatively intelligent. It is monitored by the team of Guanglian and supported by a special sd-wan technology professional team. Therefore, for enterprises, the cost of operation and maintenance is relatively low.

Sd-wan is a complete networking solution using software to define Wan, and it is also a service, which is not limited to the use of a certain broadband. More often, several high-quality broadband may be assembled in the SD WAN network of large enterprises, such as when Beijing head office uses Netcom broadband and Henan branch uses Telecom broadband, SD Wan can access two kinds of broadband through networking, combined with the MPLS VPN backbone network of optical Union, so as to achieve high-quality mutual visits between enterprise headquarters and branches, departments and departments. Take the sd-wan networking scheme of Guanglian group as an example. While realizing the exchange of visits between stations, enterprises have more confidential data and important applications, and have higher requirements for network security and stability. The sd-wan Wan Wan Wan of Guanglian group can ensure network security and stability through a series of technologies and services. That is to say, using sd-wan, enterprises enjoy not only stable broadband, but also a series of networking architecture design, operation and maintenance monitoring and other services, so that enterprises can achieve a smoother, safer and simpler network experience.
