There are still many advantages of optical link special line access, and optical link provides the overall solution of the network. For example, it is relatively flexible, which is reflected in its effective access to the networks of many operators; Then, the operation and maintenance is relatively professional. The schedule operation and maintenance and fault handling are all provided by the engineer team of Guanglian. The enterprise has the opportunity to greatly optimize the efficiency, response and cost of network operation and maintenance, which is very professional. In addition, if large multinational companies use the most special lines of Guanglian now, because Guanglian has more international resources and has been doing it for a long time in the field of transnational special lines. The last important point is high-speed, technology determines speed, speed determines experience, optical Union's technology in network management is the top in the industry, optical Union's special line will not be stuck in general, the quality is higher, which is worth affirming.

It's the same as what happened to our company before. Because of the continuous shift of business and office to online, various network applications are increasing, resulting in a surge in MPLS dedicated line traffic. In this case, the company not only faces the problem of increasing network costs, but also the most important thing is that the application experience has declined. Sometimes a very urgent task is affected by the network Caton, which is unbearable for the company's online system applications. We are now using the sd-wan networking scheme of Guanglian group, which is a different networking scheme. But don't worry, it won't be too much trouble to change your network. It is equivalent to optimizing and upgrading on the basis of the original special line, and the current architecture implements double machines and double networks; In terms of network, intelligent optimization of links to improve bandwidth utilization. Perhaps also because the previous network experience has not been very good, after upgrading to the dual computer dual network scheme of optical link, colleagues said that the company's network speed was like "on and off".

Let's talk about VPN first. With the development of network, more and more enterprises need to use public network to build private private network, that is, virtual private network, VPN was born. MPLS VPN is one of the fastest developing and most widely used technologies in VPN technology. MPLS VPN is an IP-VPN based on MPLS technology, which has good scalability and flexibility, and is mainly used to flexibly meet the business needs of enterprises. I have seen the business brochure of Guanglian group before, in which its MPLS VPN networking scheme customers basically cover all walks of life, such as group enterprises, logistics enterprises, outsourcing enterprises, Internet enterprises and so on. In fact, when you need to realize the networking between headquarters and branches, the networking between sites, the networking between new sites and the original network system, and the mutual visits between internal data centers and applications, MPLS VPN networking technology can be used. And now MPLS VPN networking will have service providers like Guanglian group to provide comprehensive and perfect solutions, which is very convenient and fast.

At present, more and more enterprises use sd-wan networking. For example, our enterprises and the enterprises of some it friends are upgraded from MPLS networking to sd-wan networking. Now the networking technology of SD Wan has been relatively stable. Our company upgraded to sd-wan at the beginning of last year, cooperated with Guanglian group, and Guanglian provided a complete sd-wan networking solution. This solution includes not only the networking itself, but also a series of operation and maintenance work after the networking, which is quite worry free for enterprises. The most important thing is to liberate enterprises from the traditional basic operation and maintenance work and focus on the realization of core it values. From the aspects of cost, deployment speed, network flexibility and network security, you will obviously feel the advantages of sd-wan. Today, MPLS private network is still common, we can actually combine sd-wan and MPLS architecture to form a stronger sd-wan high-speed network.
