An Architecture for Self-Reconfiguration of Convergent Telecom Processes

Abstract

A convergent process is usually defined as a composition of telecommunication and Web services. Automated composition of convergent processes has been addressed actively in the last years. However, during execution phases some services may fail and therefore some mechanisms must be implemented for recovering automatically the normal execution. Furthermore, in Telecommunication environments, this process may be time-consuming and may violate the initial constraints established by the user's context and preferences. Our approach focuses in reducing the reconfiguration time while holding the initial constraints. To achieve this goal, this paper presents an iterative algorithm which does not replace individual services but whole regions of services, specified with Hierarchical Tasks Networks (HTNs). This algorithm is part of the reconfiguration module of the AUTO framework, whose architecture and performance are discussed to show that our approach can efficiently repair convergent processes in telecom environments.
