A Two-Leveled Web Service Path Re-PlanningTechnique

Abstract
Web service paths can accomplish customer requirements. During the execution of a web service path, violations of service level agreements (SLAs) will cause the path to be re-planed (healed). Existing re-planning techniques generally suffer from shortcomings of ignoring the effect of requirement change. This paper proposes a two-leveled path re-planning technique (TLPRP), which offers the following features: (a) TLPRP is composed of both meta and physical levels. The meta level re-planning senses environment parameters (e.g., requirement change and analysis/design errors) and re-plan the affected component paths produced by system design. (b) The physical level re-planning algorithm possesses the ability of web service path composition. (c) The re-planning algorithm embeds an access control policy that computes a successful possibility for every path to facilitate avoiding execution failure caused by web service access failure.
