Dynamic code binding for scalable operating system in distributed real-time systems

In this paper, we present a dynamic code binding (DCB) method for scalable architecture of operating system in distributed real-time systems. DCB means that binding for calling functions among kernel and servers is executed at run-time through function link tables, unlike traditional binding method through symbol tables. DCB overcomes the restriction that servers can not be replaced when system is running in current micro-kernel structure, therefore improves the systems' extendibility and flexibility. In addition, we use remote system call (RSC) to execute system primitives in remote sites using DCB. This is done at kernel level, so it provides more faster and simple interface than user level RPC. So RSC makes it easy to develop program in distributed real-time systems.
