Aspect-monitor: An Aspect-based Approach To Ws-contract Monitoring

Contract monitoring is carried out to ensure the Quality of Services (QoS) attributes and levels specified in an electronic contract throughout a business process enactment. This paper proposes an approach to improve QoS monitoring based on the aspect-oriented paradigm. Monitoring concerns are encapsulated into aspects to be executed when specific process points are reached. Differently from other approaches, the proposed solution requires no instrumentation, uses Web services standards, and provides an integrated infrastructure for dealing with contract establishment and monitoring. Moreover, a Business Process Management Execution Environment is designed to automatically support the interaction between customer, provider and monitor organizations.4 SAIC512(2010) BPMS from Active Endpoints, , http://www.activevos.com/, Retrieved October 12, 2006Benbernou, S., State of the art report, gap analysis of knowledge on principles, techniques and methodologies for monitoring and adaptation of SBAs (2008) Technical Report (Project Deliverable), , Université Claude Bernard Lyon, FranceBianculli, D., Ghezzi, C., Monitoring conversational web services (2007) IW-SOSWE'07, 2nd Int.

Improving Qos Monitoring Based On The Aspect-orientated Paradigm

Contract monitoring is a complex activity which requires code instrumentation and many additional functions to be implemented both in the client and server sides. This paper proposes an approach to simplify QoS monitoring based on the aspect-orientated paradigm. The objective of this paradigm is to increase modularity by allowing the separated expression of cross-cutting concerns and the automatic reunification of them into a whole system. We consider that an e-contract consists of collaborative partners, a business process specified in AO4BPEL and QoS attributes defined with WS-Agreement. Monitoring concerns are encapsulated into aspects to be executed when specific process points are reached. Differently from other approaches, the proposed solution requires no instrumentation, uses Web services standards, and provides an integrated infrastructure for dealing with contract establishment and monitoring. Moreover, a Business Process Management Execution Environment is designed to automatically support the interaction between customer, provider and monitor organizations. © 2011 Springer-Verlag Berlin Heidelberg.73 LNBIP421435Inst.
