Thorough dissection of SD-WAN service

  • SD-WAN with virtual WAN technology provides the following four key capabilities:

    • Network bonding - Multiple MPLS and broadband paths can be combined into a single virtual WAN. This capability enables organizations to enhance high-cost MPLS with a lower cost broadband solution to maximize bandwidth. Because there are multiple WAN links that can load critical traffic at the same time, it helps to eliminate packet loss and downtime issues.
    • Smart Path Selection - Virtual WANs can select network paths based on individual packets to achieve optimal bandwidth efficiency and adapt to changes in one second.
    • Application awareness - Virtual WANs can reduce the priority of critical applications such as VOIP and point-of-sale transactions by identifying and prioritizing mission-critical application traffic, while non-critical traffic such as video is reduced. . In the event of one or more path failures, critical applications can quickly switch to the remaining paths to maintain uninterrupted productivity.
    • By leveraging the Internet path, virtual WANs allow direct connection to cloud services , allowing businesses to take advantage of cloud applications and services without major network upgrades.

    In addition to providing greater resiliency and resiliency than MPLS-only network policies, virtual WANs can increase your network service agility. Because you can use multiple networks simultaneously without gaps, and you can add, change, and discard services without affecting other services, you can make network vendor decisions based on your own schedule. Figure 2 shows that multiple networks are combined within a virtual WAN.
