• The client gets the interoperable OR(IOR)

• stubs can be generated automatically using IDL compiler & are included in code during compilation.

• The client stub calls network relations using system calls.

• ORB transfers marshalled data using CDR format(common character data represantation) to OA

• OA then transfers calls to servers skeleton.

• server skeleton unpacks/unmarshalls the parameters and call procedure.

• server does the work & returns result to skeleton.

• the skeleton then packs result and send to OA

• OA then sends it to ORB and ORB transmits results to client.
