Almost everything has changed, including network provisioning, configuration and change management, fault location process, performance monitoring, and security and compatibility. And confirmation of validity. The complexity of enterprise networks is growing, and the wan of enterprises is also growing. This ability to implement both virtual IP networks and automatic configuration management of the underlying wan network is a key feature required for enterprise networks in severe load environments. Many of the hybrid network capabilities of SD-WAN vendors are still in their early stages. One of the key issues companies need to consider is who manages the environment, especially as SD-WAN begins to be applied to more complex networks. Overlay is a feature of most SD-WAN solutions, which has become an important concept in hybrid networks. As packet forwarding decisions are transferred to the overlay, bandwidth in the network is available as a resource pool for the solution. . However, a key feature of advanced SD-WAN solutions is the ability to collect large amounts of telemetry data to influence forwarding decisions—not just at the circuit level, but along the entire path. Because SD-WAN is used in more complex enterprise environments, it is necessary to understand and participate in traditional routing protocols. Companies using SD-WAN today need to use workarounds or simplified methods in some cases to accommodate the current state of the technology. Gartner said in the December 2015 SD-WAN Market Guide report that at this stage of the market, the main target market is the enterprise that manages the WAN internally, because the SD-WAN solution can greatly ease the deployment and management of the WAN. The operational burden of the solution. However, in order to reduce the time-to-delivery and increased flexibility of hosted WAN services, some network service providers are beginning to take full advantage of SD-WAN technology.

In the past, the traditional telecom equipment was built, the investment cost was high, and it was not easy to modify after the construction. Therefore, it is often necessary to make a complete functional plan at the initial stage of construction, and the investment for expansion is also expensive; the software-defined network (SDN) can be used. Virtualized machine and software modification service functions, hardware investment costs are reduced, and expansion flexibility becomes higher. Japan Lotte Telecom grabbed the 5G license and built the infrastructure with Software Defined Network (SDN). Rakuten has established a brand new 5G telecommunications network in Japan for a short time, which is 40% lower than traditional telecom operators. It can be cheaper, faster and more reliable. It breaks the monopoly of Japan Telecom and relies on software-defined network architecture. Lotte has also screamed the goal of 10 million customers for 9 years. Not only the new telecom operators are active, but also the large-scale e-commerce companies have seen the advantages of SDN. The first point of the SD-WAN is to change the computer room environment of the "special-purpose machine for special functions" in the past, which is set by a general-purpose server through software. Flexible switching function, because the technology is becoming mature in 2019, the price is also suitable to start, it will be a year of SD-WAN outbreak! ## Shareholders are concerned about the stock price and see the next five-year transformation of Ruiqi Optimistic about the SD-WAN demand, Taiwan's industrial Netcom big manufacturers have also switched their business, and the current shipments are at the leading end. In the first four months of this year, the revenue was 2.383 billion yuan, an increase of 16%. Realtek is actively catching up. At present, revenue is only half of the market, but the revenue of SD-WAN products in the first four months accounted for 22%, which is higher than last year's 16%. General Manager Hong Defu said that Ruiqi is actively Transformed from a pure network security vendor to a solution provider.

Software-Defined Wide Area Networking (SD WAN) is a transformational approach to simplify branch office networking and assure optimal application performance. SD-WAN is a more established but also fast-growing approach, providing an inroad into the enterprise for the disruptive, new-age software-defined networking (SDN) movement that sees more open, interchangeable software solutions overtaking legacy, proprietary, hardware-based systems. Commonly reported benefits of SDN include agility and flexibility, lower costs and increased performance. As the SDN movement matures from early testing and proof-of-concept efforts in academia and test labs -- mostly targeting major service providers and carriers -- SD-WAN solutions are increasingly penetrating the enterprise networking space.After claiming to be the first provider to make mobile 5G service live in the U.S. on Dec. 21, 2018, AT&T yesterday announced a partnership to implement 5G capabilities into the company's SD-WAN offering.

Carrier-grade MPLS connections are typically affected by supply time and are generally more expensive, while Internet links are typically much cheaper than carrier-grade MPLS connections, and SD-WAN technology enables organizations to effectively utilize all available network connections to meet all their needs. Without worrying about maintaining an idle backup link. Traffic encryption is more secure At the security level, SD-WAN can encrypt traffic during WAN traffic transmission and improve network security by fragmenting the network. Once compromised, the loss can be minimized. SD-WAN also helps IT administrators continuously monitor the amount and type of traffic on the network and quickly detect attacks. SD-WAN infrastructure revenue increased by 83.3% in 2017 to reach$833 million, and the market is becoming more competitive. Traditional network providers are looking for M&A strategies to complement their existing products or in this rapidly expanding Get a foothold in the market.

Rohit Mehra, vice president of IDC's network infrastructure at International Data Corporation, said that the emergence of SD-WAN technology is one of the fastest industry transformations seen over the years, and organizations of all sizes are modernizing their WANs for a range of Cloud-enabled applications provide a better user experience.

According to the prediction of authoritative organizations, the total expenditure of global Internet of Things will reach 772 billion US dollars in 2018. The widespread application of Internet of Things is developing rapidly. From asset tracking, equipment monitoring to machine maintenance, it will bring a huge change to the traditional industry. In the Internet of Things industry, network communication is the key to development. Software-defined wide area network (SD-WAN) technology is sweeping the entire industry and has grown from emerging technologies in 2017 to 2018.

SD-WAN Software-Defined Wide Area Network, which means to establish a virtual network in one or more physical networks. It has the same concept as SDN, which realizes the separation of forwarding and control to simplify the network. Management and operation. The WAN (Wide Area Network) refers to a private communication network that is distributed in different locations and connected to multiple LANs.

The main purpose of SD-WAN is to achieve a network quality of dedicated lines, reduce traffic costs, and improve bandwidth utilization by utilizing a series of technologies such as software technology, application strategy deployment, and overlay network. At the same time, for multiple stations According to the current network conditions and configuration policies, the optimal path can be automatically selected to achieve load balancing and ensure network quality of the entire network.

Technical research and various attempts are intended to be a big part of the SDN era. SDN already has a relatively complete technical system support, and the Openflow protocol is the core technology of its implementation. However, because everyone has different understandings of SDN, the implemented controller software can only control their own hardware devices, and can not form a generalized software. This is also to achieve competitive advantage and exclude other software manufacturers. Obtaining more markets, which makes the SDN technology landing slower, affecting the development of SDN to some extent. Even so, SDN is still developing rapidly in technical theory. Soon it also has brothers and sisters SD-WAN and SD-branch, so SDN and SD-WAN, SD-branch formed three brothers.

The SD-WAN full name is a software-defined wide area network. In 2015, it became a hot topic in SDN technology, and the first SD-WAN product appeared on the market. SD-WAN inherits the concepts of SDN control and forwarding separation and centralized control. It deploys SDN technology in WAN networks, mainly uses software advantages to improve network performance and reduce costs, while ensuring security and stability and easy deployment. The basic principle of SD-WAN can be understood as establishing a "virtual network" on top of one or more different physical networks or network services, as long as the mapping between virtual and physical can be done. There is no need to know what technology is being used for things inside and outside the virtual network. In the past, we mentioned that SDN is mainly used in data centers and regional networks. SD-WAN extends SDN to WANs. There are many protocols in WANs, which are different from Ethernet protocols in regional networks, so it is not simple. The migration, but need to do some specific design for the WAN. SD-WAN can operate by measuring basic network traffic metrics such as latency, packet loss, jitter, and availability. With this data, SD-WAN can actively respond to real-time network conditions and choose the best path for each packet. SD-WAN has a central controller concept for global network visibility. Network administrators use the controller architecture to create policies and allow the system to take action without explicit manual change control. This controller platform performs policy-based forwarding based on current WAN conditions and complete information on enterprise application preferences, enabling immediate global changes without the need to manually log in to each router. The SD-WAN device is not necessarily a dedicated device. The SD-WAN device can be a simple x86 server containing computing resources for application policies and a 1GE NIC.

SD-WAN architecture is an attempt to abstract the majority of the network infrastructure between different LANs through network service providers. The SD-WAN architecture uses an SDN controller to create flow tables relative to routing tables that rely on edge routers.

For example, if the destination of Internet boundary traffic from a local area network is a branch office throughout the country, the routing of the data packets depends on the information flow table set by the SDN controller.

If you need to make changes to the routing configuration, handle it on the controller and allow the generated process table to be sent to the relevant network device. This is different from traditional network configurations where administrators are responsible for the collaboration of various server and network teams to ensure that applications can communicate with remote locations through existing network infrastructure.

Although SD-WAN engineers may not be the actual job, SD-WAN and SDN are usually the concept that network administrators and system administrators must understand in the future. Network engineers who are unfamiliar with virtualization, server applications, and server operating systems will fall behind the times. In addition, because the SD-WAN architecture is considered to be a multi-protocol label switch, you should be familiar with the various existing SDN protocols, such as OpenFlow and SDN OpFlex, while reducing the time spent on some of the more traditional routing protocols.

The advantages of the SD-WAN architecture have not been fully reflected, and company-level applications will slowly help the technology become mainstream. However, large companies like Cisco and Verizon will continue to invest in research and development, and it is wise for network administrators to familiarize themselves with SD-WAN as soon as possible.

Software-Defined Networking (SDN) has become an important part of modern data center management infrastructure, and administrators can use a controller or cluster of controllers with software-defined capabilities to configure network devices in their data centers. This means they no longer need to configure each switch, router and firewall separately to ensure proper configuration and connectivity.

However, as software-defined networking technologies, including software-defined wide area networks (SD-WANs), evolve in data centers, administrators need to expand their management strategies accordingly.

Adoption of SD-WAN architecture

This year, SD-WAN was adopted by a number of companies. In September, Verizon became the first US carrier to actually implement SD-WAN deployment, but no other carrier has deployed SD-WAN. According to analyst firm IDC, the adoption of SD-WAN architecture in enterprises is relatively slow, but IDC expects SD-WAN adoption in the enterprise to grow. IDC predicts that by 2020, the SD-WAN enterprise market revenue will reach \$6 billion, as companies hope to take advantage of the simplicity and security that SD-WAN brings. As early as 2015, market research firm Gartner predicted that by the end of 2019, 30% of enterprises would deploy SD-WAN technology in their branches.

The SD-WAN architecture attempts to abstract most of the network infrastructure currently connected to various regional networks (LANs) through Internet service providers. The SD-WAN architecture creates flow tables through SDN controllers without relying on edge router routing. table. For example, if Internet-bound traffic from the LAN is sent to branch offices located throughout the country
