What is SD-WAN?

The software-based global network (SD-WAN) applies the concept of network solutions (SDN) to Wide Area Network (WAN) networks. SD-WAN technology abstracts traffic management and monitoring from network equipment and applies them to individual applications to achieve improved application performance, provides a high-quality user interface in geographically dispersed locations, and simplifies the deployment of broadband and cloud networks.

How does SD-WAN works?

Modern enterprises rely on global networks to support a growing number of business-critical applications, such as virtual desktops, VoIP and videoconferencing platforms, ERP and CRM systems, as well as other corporate or cloud applications. These applications often have bandwidth and require high reliability and quality of service. When they slow down even for a few seconds, employees notice, and productivity suffers.

The traditional way to solve WAN problems and meet the performance and reliability requirements is to update the network bandwidth. But this is not cost-effective and does not prioritize critical applications. It also does not affect the changing nature of applications and data, which are increasingly found in public and private clouds computing.

SD-WAN technology enables the creation of a hybrid WAN architecture that combines multiple MPLS, mobile and broadband paths together to provide a single, logical, virtualized path that can dynamically adapt to network conditions. It also allows you to make decisions about prioritization for each application, using a very granular application classification to ensure that priority priority applications always perform very well. As an alternative to next-generation WAN optimization, SD-WAN technology takes into account the growing demands for branch office applications and infrastructure.

Advantages of SD-WAN

SD-WAN solutions offer many advantages to meet the needs of modern corporate networks, including:

  • Improved application performance and quality of service for remote and branch employees
  • Reduce WAN costs and scalability through the use of low-cost broadband and mobile connections
  • Increased flexibility to prioritize mission-critical applications compared to other network traffic
  • Improved business continuity and disaster recovery capabilities that support communication even during multiple network failures
  • Improved reliability of the connection in the WAN as applications and data are transferred to the cloud
  • Reducing the complexity of branch networks by consolidating services into an integrated WAN peripheral and centralizing management and policy definition
