We have been requested to try and loadbalance requests to a Campus department
with their own Radius (IAS) server for their wireless users. We currently
proxy to them from our Radiator server(s) for their users, however, their
current server cannot handle to load. They have added 2 new servers to their
environment and we have configured a test server to test the <AuthBy
VOLUMEBALANCE, ROUNDROBIN> features of Radiator. We are experiencing, what
appears to be excessive delays in responses from their servers in this
configuration. We have tested each server individually while configured as
<AuthBy Radius> with multiple host clauses, and although, the response times
are immediate, there is no guarantee, that I can find from the documentation
that a failed/timedout request will go to the next host listed in the AuthBy
clause. Attached is the trace 4 log of the <AuthBy VOLUMEBALANCE> attempt.
Any assistance or recommendations is greatly appreciated.
here is the portion of the config used:
# Dept identifier
