Abstract

We introduce a noble fault-tolerant distributed real-time operating system, SROS (Scalable Real-time Operating System), that is successfully implemented and working in an ATM switching system for B-ISDN. SROS is based on a micro-kernel for the purpose of achieving portability, scalability and reusability. In addition, to reduce system development period and to preserve call service continuity during system/application software upgrade, SROS adopts a dynamic code binding (DCB) method that enables system/application software upgrade without system halt or service disconnection. We also propose a cool development environment suitable for an embedded, distributed real-time system. This environment, together with SROS mechanisms, greatly cuts down the system development time
