DR-OSGi: Hardening Distributed Components with Network Volatility Resiliency

Abstract. Because middleware abstractions remove the need for lowlevel network programming, modern distributed component systems expose network volatility (i.e., frequent but intermittent outages) as application-level exceptions, requiring custom manual handling. Unfortunately, handling network volatility effectively is nontrivial—the programmer must consider not only the specifics of the application, but also of its target deployment environment. As a result, to make a distributed component application resilient against network volatility, programmers commonly create custom solutions that are ad-hoc, tedious, and error-prone. In addition, these solutions are difficult to customize for different networks and to reuse across different applications. To address these challenges, this paper presents a systematic approach to hardening distributed components to become resilient against network volatility. Specifically, we present an extensible framework for enhancing a distributed com...
