AltocumulusISP link latency
We are currently load balancing internet outbound traffic via two ISP links. The transparent monitor is configured to verify the health of ISP links. However, we would like to monitor the ISP link latency and make load balancing decisions in addition to the link reachability. Is it possible?
Any pointers to the F5 KB article and solution document will be helpful.
The link controller module is not provisioned.

Hi ,

This seems more like for dedicated SD-WAN solution not F5 BIG-IP that can monitor for latency between two locations that have SD-WAN devices or to a SaaS service by using probes that take the latency into account and dynamically changes the selected ISP links depending on the current latency.

indeed.
i used to sell sdwan router and it has such auto link latency measurement as basic feature.
msrp was also lower than cisco wan router.- Nikoolayy1
F5 is a swiss army knife but it can't replace everything a corporate network. An older approach will be if a router even without SD-WAN features supports ip sla probes (this is what cisco calls them) and you can have 2 static routes and one to be removed if the sla marks the route as bad but better just go with an real SD-WAN solution as that is grandfather of SD-WAN 😁
