Step 1.
The concepts in the following subsections are for the advanced RPC developer. The first
subsection discusses how clients obtain endpoints when using partially bound binding
handles. Then we discuss how a system buffers call requests and how a server queues
incoming calls; this information is relevant mainly to advanced RPC developers. The
final subsection discusses how a server selects the manager to execute a call; it is
relevant for developing an application that implements an interface for different types of
RPC objects.
