#### 4.3.2 Configuring protocol personality preferences

The user may affect a preference to each protocol personality. The protocol with the higher preference will be selected among possible protocols to send a request to a remote node.

See `polyorb.binding_data.<protocol>.preference` in section `[protocol]` to set up protocol's preference.

Possible protocols are defined as the protocols available on the remote node, as advertised in its object reference. `IOR` or `corbaloc` references may support multiple protocols; `URI` references support only one protocol.

Each protocol supports a variety of configuration parameters, please refer to the protocols' sections for more details.
