What is the value of an SD WAN solution

SD-WAN is a service formed by applying SDN technology to WAN scenarios, which is used to connect enterprise networks in a wide geographical area, including enterprise branch offices and data centers.

SD-WAN is the specific application of SDN technology in WAN connectivity such as broadband Internet, 4G, LTE, and MPLS, which can connect enterprise networks (including branch offices and data centers) across geographic distances.

SD-WAN provides dynamic, policy-based application path selection across multiple WAN connections and supports service linking for other services such as WAN optimization and firewalls.

SD-WAN is an architecture that utilizes a hybrid WAN of at least two or more connection types such as MPLS, broadband internet, 3G 4G, etc. SD-WAN includes a centralized, application-based policy controller that provides intelligent path selection, as well as an optional router.

SD-WAN can be easily deployed with CPE and automatic elastic networking, which can be interconnected.

In fact, SD-WAN is software-defined WAN, which is mainly to connect a wide range of enterprise networks, data centers, Internet applications and cloud services, in general, it is a service formed by applying SDN technology to WAN scenarios, which is to help users reduce the cost of wide area network (WAN) and improve network connection flexibility. Let's take a look at the specific role of SD-WAN.

What is the role of SDWAN?

1) Support enterprise cloud: optimize the access experience of cloud applications, and integrate public cloud and private cloud.

2) Application experience optimization: automatic identification of key applications and optimization of user experience.

3) Reduce the cost of private lines: the integration of private network line resources, the improvement of line bandwidth utilization, and the replacement of private lines by Internet lines.

4) Simplified O&M: Automatic on-line and unified management of devices, flexible policy deployment.

5) Improve network security: multi-tenant isolation, integrated security functions, and traffic scheduling of regional security centers.

It can be seen that the benefits of SD-WAN are that it is cost-effective and easy to use. It is worth noting that during the implementation and migration process, enterprises need to plan reasonably and provide an implementation plan that is compatible with the existing network to ensure the continuous normal operation of the network and reduce the risk of downtime. Effectively implement security segmentation to meet specific requirements for compliance, threat detection, content security, data loss prevention, and a variety of other security domains.

Intelligent routing. According to the user's bandwidth demand and the real-time network situation, the global load balancing and path optimization of network traffic are dynamically realized. Moreover, it can quickly respond to link interruptions or abnormalities in the network and re-plan the path.

Flexible access. According to different user types and business requirements, plug-and-play terminal equipment or virtualization deployment is used to access through the Internet, 4G, MPLS private line and other modes.

Cloud-network convergence. Support any interconnection between mainstream public clouds, private clouds, data centers, branch offices, and the Internet of Things.

Unified management. The unified user management platform can fully visualize the networking topology, node status, and link status, and users can understand the status of the entire network in real time.

The biggest advantage of SD-WAN and the reason why many companies turn to it is cost.

The expansion of MPLS and private line networks has become extremely expensive for companies looking to save money.

SD-WAN can be managed from ** locations via an application, unlike MPLS circuits that must be managed at each specific site. SD-WAN is also capable of supporting the cloud.

Although the SD-WAN Department has many advantages, it is impossible to achieve perfection. The most common problem with SD-WAN is that it has no security features because it is entirely Internet-based, which means that IT professionals not only have to manage the network, but also keep it safe from attacks, as one attack can disrupt the entire network. That's why many companies are turning to hybrid SD-WAN that combines SD-WAN with MPLS to give you the "best of both worlds".

SD-WAN is a software-based networking solution that helps businesses achieve more efficient, secure, and reliable network connectivity. The following is a summary of the values and benefits of the SD-WAN solution:

Improve network performance and reliability

SD-WAN can improve network performance and reliability in a number of ways. First, it can use multiple network connections (such as internet, MPLS, 4G, etc.) for load balancing and failover. This means that even if one network connection fails, the business can still maintain the network connection.

Second, SD-WAN can improve network performance using intelligent routing and application optimization. These features ensure that network traffic always travels through the optimal path and optimize the performance of your applications.

Improve network security

SD-WAN can improve network security because it can protect corporate networks using a variety of security features. For example, SD-WAN can use encryption to protect data transmissions and prevent data breaches. It can also use features such as firewalls, intrusion detection, and prevention to protect corporate networks from cyberattacks and malware.

Reduce network costs

SD-WAN can reduce enterprise network costs because it can use multiple network connections for load balancing and failover. This means that businesses can use a cheaper internet connection instead of an expensive MPLS connection, reducing network costs. In addition, SD-WAN can reduce enterprise IT spending by reducing network failures and improving network performance.

SD-WAN solutions are already widely used in many enterprises. Here are some examples of how to use them in action:

Retail businesses

Some retail businesses use SD-WAN to connect their stores and warehouses across the country. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can reduce network costs because it can replace expensive MPLS connections with cheaper internet connections.

Healthcare Businesses

Some healthcare businesses use SD-WAN to connect their hospitals and clinics. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can improve network performance using intelligent routing and application optimization, thereby improving the quality of healthcare services.

Financial enterprises

Some financial enterprises use SD-WAN to connect their branches and data centers. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can enable the cavity sail to protect data transmission with encryption and prevent data leakage.

Due to the large differences between SD-WAN and traditional network architectures, there are more network ingress and application environments are more flexible, which also brings additional challenges to its security and performance.

SD-WAN makes full use of a rich and diverse standardized architecture to provide users with basic user devices, so that enterprise customers and communication service providers have a variety of hardware options, faster product updates, and the most competitive products.

SD-WAN users need more customized services, so the plan will always vary from person to person. SD-WAN products are charged according to the customer's actual usage needs (such as bandwidth), and are charged monthly or annually according to the service method.
