ILB is managed by the Service Management Facility (SMF) service svc:/network/loadbalancer/ilb:default. For more information about SMF, see Managing System Services in Oracle Solaris 11.2 . The three major components of ILB are:
ilbadm command-line interface (CLI) – You can use the CLI to configure load-balancing rules, perform optional health checks, and view statistics.
libilb configuration library – ilbadm and third-party applications can use the functionality implemented in libilb for ILB administration.
ilbd daemon – This daemon performs the following tasks:
Manages persistent configuration across reboots and package updates
Provides serial access to the ILB kernel module by processing the configuration information and sending it to the ILB kernel module for execution
Performs health checks and sends the results to the ILB kernel module so that the load distribution is properly adjusted
