SUMMARYThe prosperity of Internet results in a workflow executing engine's performance instability due to the request congestion for a short period of time. This paper proposes a peak load control (PLC) based orchestration system that can stably execute hybrid services. The PLC mechanism uses the delay time algorithm for controlling a BPEL engine's heavy peak load caused by the request congestion for a short period of time. In order to prove the stable performance of the PLC-based orchestration system, we analyze the proposed delay time algorithm. According to our experimental results, the proposed delay time algorithm can stably execute structured activities of WSBPEL specification in heavily overloaded state after the saturation phase and has an effect on controlling the states of peak load. In this paper, we also describe a hybrid service architecture model that can represent both Web Services and existing EAs as same type of services.

“…Distributed execution of process-based Web service compositions is an important area of research (e.g., [20,6,18,21,14,22]). However, to the best of our knowledge, very little research has been published towards applying autonomic computing principles to solve the management problem opened up by the distributed design of such engines.…”

“…The first takes various examples of orchestrations from the literature and compares their implementation in DSOL and BPEL. The second does the same but taking AO4BPEL [13] and JOpera [14] as a reference. The goal is to show the advantages of DSOL w.r.t.…”

“…As an alternative to BPEL and BPMN in the specification of service compositions, other languages, like JOpera [14] (see our specific comparison in Section 5.2.2), Jolie [32], and Orc [33], were proposed. While easier to use and often more expressive than BPEL and BPMN, they do not depart from the imperative paradigm, and consequently they share with them the same problems that motivate our work.…”

“…JOpera [14] is a mature research product that offers a visual language and a fully functional execution plataform for building distributed application composed of reusable services, which includes, but is not limited to Web Services. The graphical and visual approach offered by JOpera simplifies modeling complex orchestrations when compared with BPEL.…”
