Research on Service Update Dynamically Based on OSGi Frame

Abstract:

It is a key problem for a 7*24 running system to update and maintain online. According to the feature of OSGi (Open Service Gateway Initiative) framework, current service dynamic update policies for OSGi framework are analyzed. In order to solve the problem of service mutual consistency and service state consistency during service update, the service dynamic update policy based on publish & subscribe model is presented. This policy is based on quiescent state theory to ensure mutual consistency when services are updated online. The process of the dynamic service update policy is described by Petri net. We realize the policy using Event Admin Service in the experiment with well-defined program model. The result shows that the policy is validate and feasibility.
