EMLDC: An Efficient Method of Long Data Communication for the L4 Microkernel-Based Virtual Machines

Abstract

Microkernel-based virtualization is one of several popular virtualization technologies aiming for embedded devices and efficient communication between virtual machines should be provided as other virtualization solutions. Long data communication is one of main two communication methods. This paper proposes EMLDC: an efficient method of long data communication based on shared memory in the L4 Microkernel-based virtualization environments. Especially EMLDC adopting lock-free mechanism can reduce performance loss and priority inversion in the real-time virtual machines against traditional blocking algorithm. Benchmark programs have been conducted to demonstrate that EMLDC can support long data communication efficiently.
