Software-defined wide area network (SDWAN) is the future of enterprise networking, providing organizations with unprecedented control and flexibility over their network infrastructure. However, a critical aspect of SDWAN architecture is the mapping methodology used to direct network traffic to its destination. Two fundamental mapping approaches in SDWAN are user-to-application mapping and application-to-network mapping. This article will outline the differences and benefits of each approach, as they relate to maximizing network performance and efficiency in the enterprise environment.

Understanding SDWAN and Its Mapping Methodology

SDWAN is a technology that utilizes software to simplify the management and operation of a WAN by separating the networking hardware from its control mechanism. Essentially, it allows enterprises to access all of their applications and services without the traditional constraints of physical location or device type. The methodology used to direct this network traffic is critical to the network’s performance and efficiency. Two mapping approaches that often come up in discussions of SDWAN mapping methodology are user-to-application mapping and application-to-network mapping.

User-to-application mapping is a mapping approach that focuses on the user’s experience. It maps the user’s location, device type, and application usage to ensure that the user’s experience is optimized. This approach is particularly useful for enterprises that have a large number of remote workers or employees who use multiple devices to access applications.

Application-to-network mapping, on the other hand, focuses on the application’s requirements. It maps the application’s traffic patterns, bandwidth requirements, and security needs to ensure that the network can support the application’s needs. This approach is particularly useful for enterprises that have a large number of mission-critical applications that require high levels of performance and security.

The Importance of User-to-Application Mapping in SDWAN

One critical approach to SDWAN mapping is user-to-application mapping, where network traffic is directed based on specific application traffic types, not simply IP addresses or port numbers. This approach optimizes network paths by prioritizing traffic that is critical to the user experience. A significant advantage of user-to-application mapping is that it allows IT teams to examine the user experience and tweak network flows around that experience. This approach optimizes networks for performance, ensuring that the user experience is not compromised, even under heavy network usage. User-to-application mapping understands which applications are most critical to end-users and directs traffic accordingly, resulting in higher user satisfaction and more productive employees.

Another benefit of user-to-application mapping is that it enables IT teams to identify and troubleshoot issues more quickly. By understanding which applications are being used and how they are performing, IT teams can quickly identify and resolve any issues that may arise. This approach also allows for more efficient use of network resources, as traffic is directed only to the applications that require it, reducing unnecessary network congestion and improving overall network performance. In summary, user-to-application mapping is a critical component of SDWAN, enabling IT teams to optimize network performance, improve user satisfaction, and troubleshoot issues more efficiently.

The Role of Application-to-Network Mapping in SDWAN

Application-to-Network mapping in SDWAN is the second most popular mapping approach used in enterprise environments. This approach is centered on the optimization of network traffic based on applications and services, but not necessarily on specific users. An advantage of application-to-network mapping is that it’s easier to implement and maintain, especially in more massive enterprise environments. IT teams don’t need to be aware of the specific requirements of individual users but can instead optimize network flows around specific applications.

Another advantage of application-to-network mapping is that it allows for more efficient use of network resources. By prioritizing traffic based on the application, IT teams can ensure that critical applications receive the necessary bandwidth and network resources to function optimally. This approach can also help to reduce network congestion and improve overall network performance.

However, one potential drawback of application-to-network mapping is that it may not provide the level of granularity required for certain applications. For example, some applications may require specific network configurations or QoS settings that cannot be achieved through application-level mapping alone. In these cases, a more user-centric approach may be necessary to ensure that individual users receive the necessary network resources to perform their tasks effectively.

Key Differences Between User-to-Application and Application-to-Network Mapping in SDWAN

The primary difference between user-to-application and application-to-network mapping is that user-to-application mapping directs traffic based on the specific needs of the end-users. This approach optimizes the user experience, which is critical in today’s connected enterprise environment. Application-to-network mapping, on the other hand, directs traffic based on the needs of the application or service, but not necessarily on the needs of the end-user. While this approach is easier to implement and maintain, it can compromise the user experience and lead to dissatisfied end-users.

Another important difference between user-to-application and application-to-network mapping is the level of granularity. User-to-application mapping allows for more granular control over traffic, as it takes into account the specific needs of each individual user. This means that traffic can be directed to the most appropriate path based on factors such as location, device type, and application usage. Application-to-network mapping, on the other hand, is less granular and may direct traffic based on broader factors such as application type or network availability. This can result in less efficient use of network resources and potentially slower application performance.

How User-to-Application Mapping Enhances The User Experience in SDWAN

In the user-to-application mapping approach, traffic is directed based on the specific application requirements and user needs. The SDWAN system is continually gathering information from the network and end-users as to which applications are most important, which need more bandwidth, and which flows need optimization. This approach helps ensure that the most important traffic is always prioritized, and end-users have a more seamless experience across the network.

Furthermore, user-to-application mapping also allows for better security measures. By identifying which applications are being used and by whom, the SDWAN system can apply specific security policies to each application and user. This ensures that sensitive data is protected and that potential security threats are mitigated. Overall, user-to-application mapping is a crucial component of SDWAN that not only enhances the user experience but also improves network security.

The Impact of Application-to-Network Mapping on Network Performance in SDWAN

The impact of application-to-network mapping on network performance is more challenging to evaluate as it doesn’t prioritize specific users. However, by optimizing traffic for specific services or applications, the network’s performance can still be significantly improved. This approach can be quite beneficial when the network is being used intensively by multiple users, and there are multiple services running in the background. Prioritizing network traffic by application can help avoid the network becoming bogged down by background services that aren’t crucial to the end-user experience.

Another advantage of application-to-network mapping is that it can help identify and troubleshoot network issues more efficiently. By mapping applications to specific network paths, it becomes easier to pinpoint where a problem is occurring and which application is affected. This can save network administrators a significant amount of time and effort in identifying and resolving issues.

Furthermore, application-to-network mapping can also improve security by allowing for more granular control over network traffic. By identifying and prioritizing traffic based on the application, network administrators can more easily enforce security policies and prevent unauthorized access to sensitive data. This can be particularly important in industries such as healthcare or finance, where data privacy and security are of utmost importance.

Challenges Associated with Implementing User-to-Application Mapping in SDWAN

While user-to-application mapping offers significant benefits to the user experience, it can also be more challenging to implement and maintain than application-to-network mapping. Understanding the specific needs of each end-user and mapping their requirements to specific applications and services can be time-consuming and complex. IT teams need to be well-trained in the specifics of their network traffic needs and know how to optimize flows for the best end-user experience.

Best Practices for Successful Implementation of Application-to-Network Mapping in SDWAN

When implementing application-to-network mapping, the key is to focus on what traffic is most important to the business. IT teams need to work with stakeholders to identify the specific applications or services that are the most crucial to the business. From that point, they can prioritize traffic, optimize flows, and ensure that the network is performing as expected. Regular reviews and updates of application-to-network mappings to ensure they remain relevant and effective is also an essential part of maintaining network performance and efficiency.

Evaluating the Effectiveness of User-to-Application and Application-to-Network Mapping in SDWAN
