China blocks SD-WAN and VPN

According to foreign media reports that a new mainland China policy will take effect next week, which will have a profound impact on companies in China that rely on Internet VPN or SD-WAN access. It includes tens of thousands of foreign companies and foreign individuals.

 

According to Netease cloud headlines, SD-WAN Experts obtained China Telecom issued a notice shows that Chinese government asked China’s major commercial Internet service provider ( ISP ) in 2018 Nian Yue 11 blockade before the date of TCP port 80 , port 8080 and port 443 Of course, port 80 is TCP port that is typically used to carry HTTP traffic ; port 8080 and port 443 are used to carry HTTPS traffic. If the customers of these commercial ISPs intend to continue to access these ports, they must register or apply through the local ISP to reopen the port.

 

Bloomberg early last months for the first time reported the new rules will be in 2018 Nian news before the implementation of months. And this is the first time given a specific date.

 

2017 Nian months, China Telecom sent a letter said to corporate customers, the future only allow VPN connection to the corporate headquarters overseas.

SD-WAN and traditional network

 Because SD-WAN and traditional network architecture are very different, network access becomes more and the application environment is more flexible, which brings additional challenges to its security and performance. Li Hongkai, general manager of Fortinet China, pointed out: “SD-WAN is a cross-border technology. The advantages of traditional network vendors in this field are not obvious, and users need to identify applications, security, quality of experience, performance and other aspects on a network basis. It gives Fortinet a huge opportunity. And in the traditional network architecture, security and large network design are separate, and SD-WAN turns WAN into LAN, security issues will be exposed, Fortinet directly integrates security into the underlying network. In the architecture, users do not have to think about security construction separately, so the integrated design will greatly promote the effectiveness of enterprise network security construction.”

 

  Currently, integrated SD-WAN solutions have become a significant trend in the evolution of the networking industry. With the deployment of integrated SD-WAN solutions, users can not only gain security, scalability, performance, cost and other capabilities, but also get one-stop delivery of network capabilities, while achieving unified operation and maintenance and management, and promoting network The continuation of operation and maintenance.

 

 ”SD-WAN + NGFW” Fortinet Introduces Integrated SD-WAN Solution

 

  Based on the concept of integration, Fortinet has launched the Secure SD-WAN solution, which includes best-in-class next-generation firewall (NGFW), SD-WAN, advanced routing and WAN optimization capabilities, and is securely powered in a unified product. Wide area network edge conversion. At the security level, Fortinet has the security capability to cover the entire attack plane, and supports multiple secure SD-WAN architectures. In the first test of the software-defined WAN in NSS Lab, it received a “recommended” rating; performance, cost, etc. In terms of Fortinet’s SD-WAN professional chips, it delivers up to 10x performance improvement over traditional devices, while being among the best in terms of VoIP and video traffic quality of experience, connectivity and price/performance.

 

  Fortinet China Technical Director Zhang Luo pointed out: “The outstanding advantage of Fortinet Secure SD-WAN solution is that it has got rid of the isolation status of various types of solutions in the current SD-WAN market and provides excellent security in the integrated platform. , scalability, high performance and unified management capabilities. For users, they can get a proven and optimized SD-WAN solution without the time and effort required to integrate SD-WAN.”

Fortinet Introduces Integrated SD-WAN Solution

The software-defined wide area network (SD-WAN) has been widely welcomed by enterprise customers because it can help users reduce the cost of wide area network (WAN) and improve the flexibility and scalability of network connections. The market for SD-WAN “Blue Ocean” is rapidly Change to “Red Sea”. In the crowded SD-WAN market, Fortinet believes that users need to meet not only the quality of experience, network performance, scalability, but also the tough security challenges. Based on this concept, Fortinet integrates professional SD-WAN devices with Next-Generation Firewall (NGFW) to provide high-performance, strong security, high scalability, and application-aware SD-WAN capabilities for different network-scale applications. .

Integrated SD-WAN solution becomes the trend

Compared with the traditional network system, SD-WAN is built on a transparent, controllable and predictable white-box system. It can define and virtualize the network resources needed. It has flexible networking, fast provisioning, fast cloud entry, centralized management and control. Many advantages, such as value-added services, can effectively cope with complex network services and become an important direction of current network evolution. According to Gartner’s forecast, by the end of 2019, 30% of enterprises will deploy SD-WAN in their branches, and large-scale commercialization will occur within five years. CBInsight’s research report also shows that SD-WAN has become the most preferred IT technology for enterprises in 2019.

SD-WAN APPLICATIONS CONTINUE TO GROW RAPIDLY

Gartner, an international research and advisory firm, recently completed a survey that outlines some of the key issues organizations face in implementing SD-WAN solutions and strategies to address them. According to IDC, SD-WAN technology has grown rapidly over the past two years, with the market expanding rapidly from $225 million in 2015 to $1.3 billion this year. Some experts predict that it will increase to $4.6 billion by 2022.

Traditional multi-protocol label switching (MPLS) is very expensive, and it is not suitable for cloud computing, SaaS, and mobile network applications. The MPLS drawbacks are gradually exposed, and SD-WAN is gradually being operated. Commercial and network equipment manufacturers are recognized for production.

Software-defined wide area network (SD-WAN) simplifies branch office networks and maximizes the performance of applications over the Internet and hybrid WAN, including the operation of many network services such as PaaS Platform as a Service ( Platform as a service), IaaS infrastructure as a service, multiple cloud network connections, and direct network connectivity for BYOD Bring Your Own Device.

SD-WAN technology

However, the current situation is that each SD-WAN supplier is in a separate position, and the solution provided cannot form a unified standard, which has caused a certain degree of obstacles to the operation and coordination of the network and the promotion of the technology itself.
On the other hand, there are many companies in the reality that the enthusiasm for SD-WAN is not as high as expected. Some of the respondents even expressed concern about the reliability of the technology under the traditional Internet protocol and the occupancy rate of the bandwidth. .
At present, with the continuous increase of network access bandwidth and backbone capacity, enterprises, terminals and data centers and other entities have continuously increased the demand for mobile interconnection, which has brought about changes in the traditional WAN market. SD-WAN technology as such The representative of change provides a simple and efficient WAN implementation that is sought after by most practitioners.

 

In the future, with the further improvement of network access technology and access requirements, the field of WAN deployment represented by SD-WAN technology will surely usher in greater development.
