Currently, one of the simplest and most effective ways for people to gain an in-depth understanding of computer networks is through hands-on practice and experimentation on software platforms. While education is important for the field of computer ...
EXCHAIN: exception dependency analysis for root cause diagnosis
Many failures in large-scale online services stem from incorrect handling of exceptions. We focus on exception-handling failures characterized by three features that make them difficult to diagnose using classical techniques: (1) implicit dependencies ...
