Service Execution Time Estimation in Real-time SOA
Yeo-Ja Kim, Jeong‐Yong Byun · 2009
If the existing real-time systems are integrated based on SOA, real-time SOA should be developed. Generally, in real-time SOA a service can be divided into several small services and their estimated execution time is given by provider systems. However, an estimation, which analyzes time elements related to transmit and receive messages among requesters and providers, is needed. In order to enhance QoS of Web service, this paper proposes enhanced worst-case execution time estimation by considering WS-transaction and common use of multi-processors system.
