Upload, Performance Modeling, Hard Real-time Systems
This paper introduces a new uploading system that auto
matically uploads multimedia files to a centralized server
given client hard deadlines. Unlike systems supporting
downloading applications such as video streaming and
file sharing, systems that support uploading applications
have received relatively little attention in the past decade.
While not popularly studied, uploading systems with hard
deadlines have several important applications in practice.
For instance, such systems can be used in hospitals to
gather videos generated from medical devices from various
operating rooms for post-procedure analysis and in law
enforcement to collect video recordings from police cars
during routine patrolling. In this paper, we study an
uploading system with hard deadlines in detail. We define
a suitable performance measure for the system and eval
uate the system performance via analysis and simulations.
