“…Bruneo et al (2013) present stochastic evaluation of QoS in service-based systems and evaluate parameters such as the service time distribution and the service reliability. Rak et al (2013) discuss simulation approach about SLA in cloud environment and evaluate in a predictive way the performance properties of the many different configurations. Wu et al (2013) describe automated SLA negotiation framework for cloud computing, and the design of CTR offers generation strategies and propose decision making heuristics that take into account time, market constraints and trade-off between QoS parameters.…”

In a cipher device, the OFB operation mode must be analysed for quality performance according to various secure communication channel environments. Many cipher applications have evaluated issues of security quality. This paper reviews channel transmission performance for OFB operation mode of cipher communication in a fading channel. This result contributes for Sec-SLA evaluation and probabilistic error effect of each cipher device.Keywords: service level agreement; SLA; bit error rate; BER.Reference to this paper should be made as follows: Hong, J.

International audienceThe Web service composition can be defined as the process of combining existing services to produce new ones. Indeed, composition to develop higher-level services, so-called composite services, by re-using existing services is Service Oriented Architectures (SOA) core capability. For this purpose, languages such as BPEL and platforms like the orchestration engine appeared for the specification and the implementation of service compositions. However, the expressiveness of these languages deals only with functional compositions and does not take into account the composite Web services properties validation and the tools associated to these languages do not support simulation of behavioural requirements.Our contribution consists in using software agents to provide a simulation tool to BPEL, to observe agents behaviours and to evaluate properties. Simulation plays an important role by exploring ”what-if” questions during the process composition phase. The proposed approach is implemented using JADE platform
