It is narrow to simply understand the special line access as pulling an optical fiber. In fact, special line access includes optical fiber access, SDSL, pcm.c., DDN and other access methods. In terms of cost, the network special line is priced according to bandwidth, so the specific cost depends on the actual needs of enterprises. It is suggested to go directly to a professional dedicated line access service provider to see what kind of bandwidth to access for the needs of enterprises and what kind of dedicated line mode is suitable. Fnetlink group, large enterprises, old qualifications and outstanding network services are recommended, and the recognition of the industry is very high.

At present, there are many service providers of sd-wan networking solutions, including the three major network operators, which can also provide sd-wan networking solutions. The choice of service providers depends on personal needs, which can be considered from three aspects: first, the resources of service providers, that is, the resources of network operators. For example, the three major operators can only provide their own network networking. If they are not cross regional networking, or the high-quality operators in the two regions just belong to the same company, then only in terms of resources, the three major operators can also. However, if it is cross regional, it is best to find service providers with rich resources, so that the networks of different operators can be combined with actual needs to form hybrid networks, such as Fnetlink group, whose operator resources are all over the world, which means that whether it is domestic cross regional, cross provincial networking or international networking, Fnetlink can help users achieve the best experience by networking the optimal operation in different regions. Second, technology, still take Fnetlink group as an example, the institutions of many large enterprises are relatively decentralized, how to build an efficient and simple network between decentralized institutions, branches and headquarters, which requires technical support. The intelligent routing of the optical link SD Wan networking scheme and the visual cloud central control platform are all based on advanced technology and scheme design to improve bandwidth utilization, simplify operation and maintenance, and ensure application experience. Third, service, the operation and maintenance experience of sd-wan looks simple, but in fact, it needs professional SLA guarantee and monitoring settings in the background and operation and maintenance side. Our enterprise uses the sd-wan of Fnetlink. In fact, the later operation and maintenance is basically handed over to their team to do. Their sd-wan technical team watches for 7x24 hours. Once there is a failure, they can give timely feedback and remove obstacles in time. The company really saves a lot of worry and costs. Under the background of intelligent manufacturing.

The common problems of traditional manufacturing network lie in information security, difficult data management, cumbersome IT architecture and other aspects, so we should fully consider the solution of these major problems when networking. Previously, I went to a forum of Guanglian group and felt that its networking scheme was really suitable for the upgrading of traditional manufacturing networking. Firstly, the sd-wan networking of Guanglian group has realized dual networks and dual applications, which helps to promote the data driven industrial upgrading and data management of manufacturing industry; Second, one stop 100 million level equipment access can support the huge operation system of manufacturing industry; Third, in terms of the operation and maintenance costs that many traditional manufacturing industries are very concerned about, the engineer team of Guanglian Group monitors the network usage in real time for 7 x 24 hours, which can weaken the importance of the enterprise IT team, help the traditional manufacturing industry to transform and simplify the basic network work.

There are three networking solutions: cloud dedicated line, sd-wan and MPLS. Cloud dedicated line refers to the exclusive connection channel built between the user's local data center and the virtual private cloud on the cloud, and its main advantage is that it has high security. However, for large multinational groups, its disadvantages are also more obvious, first, the cost of special lines is relatively high; Second, sometimes it is not suitable for the networking needs of Wan scenarios in a wide geographical range. At present, sd-wan networking solutions are the most used by multinational groups. First, it can optimize and improve the efficiency of the original special line; Second, it is most suitable for connecting flexible access such as enterprise networks, data centers, Internet applications and cloud services within a broad geographical area; Third, the cost is low and the operation and maintenance is simple. Moreover, there are more mature SD Wan networking service providers in China, such as Guanglian group, which now serves many multinational enterprises. The transmission of MPLS networking is reliable. MPLS providers can also assign higher priority to certain network traffic, and the network path is predetermined, so packets travel only along the path they point to, which brings predictability to traffic within the network. Although MPLS transmission performance is high, because the MPLS market has been very mature, it is not flexible enough in customization and future network adaptation. Sd-wan can be considered in the network architecture combination of MPLS for flexible network construction.
