5.19.3. Load Balancing Policies

Table 5.1. Load balancing Policies Available

Policy Name Description
first available If a healthy service binding is found it will be used until it dies. The next end-point reference in the list will then be used. There is no load balancing between the two service instances with this policy.
round robin A standard load-balancing policy whereby each end-point reference is utilised in list order.
random robin This is like the round robin, but the selection is randomized.


The end-point reference list used by the policy may become smaller over time as "dead" EPRs are removed. When the list is exhausted or the time-to-live of the list cache is exceeded, the ServiceInvoker will obtain a fresh list of EPRs from the Registry.
