Zusammenfassung:This paper describes requirements placed upon client-server interaction in a multi-server operating system and how to answer those requirements. Addressed are the problems of binding maintenance in the face of: remote method invocation, forking, binding transfer, authentication, asynchronous interruption, and client crashes. Design and implementation choices are analyzed. The solutions, used by the CMU Mach-US multi-server UNIX 4.313 SD emulation on the Mach3.O kernel, are described. The lessons learned are applicable to multi-server Os design and should be applicable to object based systems that must resolve these binding problems in a 'micro' kernel environment.
