Use SD-WAN link Management Profiles to define an SD-WAN
traffic routing across gateways in your SD-WAN network. With SD-WAN link Management Profiles, the SD-WAN traffic is
routed based on the availability or performance of the gateways. This optimizes the
performance of your SD-WAN network and adds reliability against the
network failures.
Create and configure a path quality profile, SaaS quality profile, traffic
distribution profile, and error correction profile to manage SD-WAN link
failovers.
- SD-WAN path quality profiles (PQPs)—Each SD-WAN
path quality profile (PQP) is comprised of a set of ranked metrics and thresholds
that an application requires for optimal performance.
- SaaS quality profile—The SaaS quality profile allows you to specify the SaaS
application to monitor using an adaptive learning algorithm that monitors the
application activity, or by specifying a SaaS application using the application IP
address, FQDN, or URL.
- SD-WAN traffic distribution profiles (TDPs)—As part of your
SD-WAN policy, you use SD-WAN traffic distribution
profiles to assign which traffic distribution method the path-selection algorithm
uses for an application. The path-selection algorithm uses the path metrics,
thresholds, and sensitivities as defined in a path quality profile.
- Error correction profile—SD-WAN uses forward error correction
(FEC) and packet duplication (PD) to improve the performance and reliability of IP
network. Forward Error Correction (FEC) is used to recover the lost packets by
sending extra packets for every group of four packets. Packet duplication duplicates
packets through secondary links to reduce packet loss if one link goes down.
