Ratio member is a connection-based load balancing algorithm. ... The statistics this load balancing algorithm uses will be updated when a connection is connected/disconnected. ... When SIP/MBLB calls flow containing BYE and the 'Terminate on BYE' option is enabled, a new connection will be created with every SIP call. ... That is why the ratio member seems to work in such cases. ... If 'Terminate on BYE' is disabled, or it is enabled but the call is not closed with a BYE, then all pool member traffic will be directed to the same server because the SIP traffic is multiplexed over the same connection. ... Impact ... All of the SIP traffic is directed to a single server, or the actual ratio is not maintained correctly depending on the actual calls/configuration ... FIRST WORKAROUND: Create duplicate pool members using the same server. ... For example if you have two servers, server A and B, and you want a ratio of 2:3, configure multiple pool members to achieve the desired ratio: A:506...
