Two common failures traditionally considered in the analysis of protocols are host and connection failures. The aim of this paper is to address fault tolerance for TS2PC4RS and its extension. A fault-tolerant protocol based on timeout and log records is proposed. The fault-tolerant protocol provides support for the host and connection failures that may occur during a transaction execution. The fault-tolerant mechanisms are used to meet the application domain business rules that guide the behavior of RESTful services. We describe the protocol using scenarios when failures occur.
