A Method for Web Services Fault Tolerance Based on Ripple Effect Analysis
Dong Yang, Lei Liu, Manuel Bernal Llinares · Key engineering materials · 2011
In this paper we first establish a dependency matrix over the inputs of web services in composition and the degree of dependency between the interface parameters for a single web service. Operating over the matrices, the ripple effect of a single service's fault at runtime has been analysed and computed. Based on this, we have looked for a method to substitute the failing service with an equivalent one at runtime. Using simulations and real examples we have confirmed the effectiveness of the method shown in this paper.
