http

round-robin

(optional) Specifies the load balancing policy for pure HTTP requests. This attribute applies to the HTTP part of converged HTTP/SIP requests if dcr-file is not specified. The only allowed value is round-robin, which means that the load balancer cycles through the cluster's server instances in a specified order.

sip

from-tag,call-id

(optional) Specifies the load balancing policy for SIP requests if dcr-file is not specified. Specifies the parameters on which a consistent hashing policy is applied to obtain the hash key. The default is the only allowed value.

dcr-file

none 

(optional) Specifies the data-centric-rules.xml file path name, which provides the rules for applying consistent hashing on SIP and converged HTTP/SIP requests. By default this file is not specified. If specified, this file takes precedence over the http and sip attributes. This can be an absolute or relative path. A relative path is relative to domain-dir/cluster/config.

If a request doesn't match any DCR file rules, a hash key is generated using from-tag,call-id. For an HTTP request, this is the remote host port and address.
