Failsafe means high network availability and predictable application QoE, yet few SD-WAN vendors deliver on failsafe. Oracle SD-WAN technology combines continuous, unidirectional measurement and subsecond response, delivering an intent-based network that gets traffic to where it needs to go based on the current performance reality of all WAN paths.

Oracle SD-WAN technology measures every user packet, as opposed to using round-trip test packets. The measurements are unidirectional, not simply round-trip measurements, and measure all possible WAN paths, not just one per WAN link. Oracle SD-WAN knows the current state of packet loss, latency jitter, and bandwidth utilization of the entire multi-WAN fabric between locations.

Precise, real-time measurement enables unprecedented WAN visibility and subsecond response to adapt to network issues, including not only hard link/device failures but also the soft outages (brownouts) from network congestion-based packet loss and jitter that frequently occur on a shared WAN. This subsecond response is the critical component that delivers a truly failsafe SD-WAN.

For real-time communications, Oracle SD-WAN provides even greater flow reliability by optionally replicating traffic flows along a second path, suppressing duplicates at the receiving end, ensuring calls don’t drop and delivering platinum QoE support for real-time or other delay-sensitive flows, even in the event of failures or massive congestion.

TCP was designed to cause packet loss to ensure efficiency and fairness. In a high bandwidth WAN, however, congestion-based loss at the last-mile inbound link can make it impossible to run real-time or delay-sensitive interactive applications over shared Internet links. Building on its continuous unidirectional measurement, Oracle SD-WAN technology performs air- traffic-controller, end-to-end QoS functions to ensure your last mile. inbound links don’t congest and thus can safely support real-time and interactive applications.

Oracle SD-WAN solutions can deliver a first-class travel experience for data packets moving along your network.

The controller may be set up as a high- availability (HA) pair, with active-standby appliances at the primary locations. A second appliance, or high-availability pair, can be designated in a geographically separate location as a backup controller that will take over if a complete failure of the primary NCN pair or its connectivity occurs.

Oracle’s cost-effective solution delivers critical branch IT services while reducing complexity.
