Equalizer Overview
The figure below shows the connection establishment and server failover mechanism.
For Layer 7 clusters, the connection must be established within the connect_timeout. If we receive an active
refusal (RST) from a server, we will repeat the load balancing process and choose another server. Otherwise we
will continue trying to connect to the same server until the connect timeout expires.
Fore Layer 4 clusters, the connection must be established within the stale_timeout. Here, Equalizer retries the
same server 3 times, and then chooses another server on the 4th attempt. If Equalizer receives an active refusal
(RST) from a server, the connection is dropped.
