Remote method invocation in COBRA

• 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.
• the client stub unpacks the result and returns it to client procedure.
