Best quality strategy

SD-WAN rules are used to control how sessions are distributed to SD-WAN members. Rules can be configured in one of five modes:

  • auto: Interfaces are assigned a priority based on quality.
  • Manual (manual): Interfaces are manually assigned a priority.
  • Best Quality (priority): Interface are assigned a priority based on the link-cost-factor of the interface.
  • Lowest Cost (SLA) (sla): Interfaces are assigned a priority based on selected SLA settings. See Lowest cost (SLA) strategy.
  • Maximize Bandwith (SLA) (load-balance): Traffic is distributed among all available links based on the selected load balancing algorithm. See Maximize bandwidth (SLA) strategy.

When using Best Quality mode, SD-WAN will choose the best link to forward traffic by comparing the link-cost-factor, selected from one of the following:
