A QoS View ofWeb Service Choreography
Zhao Xiangpeng, Chao Cai, Yang Hongli, Qiu Zongyan · 2007
Web service choreography describes the common and collaborative observable behavior of multiple services that interact with each other. Integrating QoS into choreography is valuable for designing and analyzing a choreography specification. In this paper, a formal model of web service choreography which incorporates QoS information such as time and cost is proposed. A formal trace semantics for the model is also given, together with several QoS estimation methods.
