Abstract

New requirements of service-oriented fault management are analyzed and a framework MDFM (Multi-Domain Fault Manager) is proposed in this paper to solve the service fault localization problem in multi-domain context. Different from current solutions, our approach decomposes SLS (Service Level Specification) based on network capability, and monitor service performance in each domain along the end-to-end path. As a result, MDFM can localize the approximate domain rapidly on which the root cause resides, therefore causative region is narrowed down and computation cost for fault analysis is reduced. Faults on both server and client sides are considered in MDFM. A prototype has been implemented to prove the feasibility and efficiency of our service fault management framework.
