Previously, several works have been carried out on hierarchical scheduling frameworks from a theoretical point of view. In the recent past, hierarchical scheduling frameworks have been implemented on VxWorks for uniprocessor system. In this paper we present our initial proposal of the implementation of our hierarchical scheduling framework in a commercial operating system like VxWorks for Symmetric Multiprocessing based (SMP) Real Time Systems. The purpose of the implementation is twofold: (1) we would like to identify the limitations of the previous implementations and (2) we would like to demonstrate feasibility of our implementation in a commercial operating system, without having to modify the kernel source code. We present SMP structure of VxWorks and how it can be used in our proposal. Finally, we present the design of our hierarchical scheduling framework, and we discuss our current status in the project
