How do we define Failsafe SD-WAN Technologies?

Failsafe SD-WAN Technologies are a set of software capabilities of an SD-WAN offering that are able to deliver predictable application performance over a multi-link WAN fabric that includes Internet connections. The most critical, baseline capabilities are continuous unidirectional measurement of packet loss, latency, jitter and bandwidth utilization, enabling unprecedented WAN visibility and sub-second response to adapt to network issues. There are other key capabilities required as well

Essentials of an SD-WAN Technology offering

To provide a failsafe SD-WAN delivering MPLS-class high availability and predictable application QoE, an SD-WAN technology offering needs to have the following capabilities:

  • continuous unidirectional measurement of packet loss, latency, jitter and bandwidth utilization. This enables…
  • per-packer forwarding decisions and sub-second response to adapt to network issues
  • Intelligent link aggregation, including the ability to use all bandwidth across multiple disparate links, even for a single high-bandwidth flow
  • optional packet replication for real-time traffic, delivering platinum quality real-time support
  • Inbound multisource QoS with inbound congestion avoidance, providing 90% - 97% sustained utilization on shared links without negatively impacting QoE
  • centralized orchestration/analytics offering highly granular WAN visibility
