Abstract

We propose a robust seamless communication architecture that enables legacy mobile terminal software designed for single-CPU processors to be run on multi-CPU processors without any software modifications. This architecture features two new technologies: proxy processes, which help achieve the design of its user-level system-call hooking and a robust design method, which reduces bandwidth variation by systematic parameter optimization. Our evaluations confirmed that this architecture achieves fundamental features with satisfactory performance, that we have succeeded in getting actual mobile terminal software to run on three CPUs without modifying the software, and that the robust design method reduces bandwidth variation by 21%.
