SLA foundation template library: reusable-component repository for SLA

Although aiming at facilitating service level management, the SLA is unfortunately not so promising for contracting SLAs is retarded by some challenges. This paper proposes to build a SLA foundation temple library (FTL) to overcome the obstacles form the perspective of SLA templates. The FTL provides a comprehensive set of well-defined and reusable components for rapid SLA development with higher quality. Furthermore, with the object-oriented approach and unified modeling language applied, the FTL also achieves extensibility and flexibility as well as legible representation.
