Abstract

Dynamic software update is very meaningful for the downtime-critical applications to reduce the downtime during the software evolution phase. Nowadays more and more complicated applications are developed on the OSGi platform. In this paper, we present a dynamic software update framework for OSGi applications, known as DSUF. DSUF can provide component-level dynamic update. It works automatically and programmers do not need to change many codes for the existing codes to fit in the framework. Experiments show that DSUF will only cost reasonable extra computer resources.
