WS-BPEL processes ought to be adaptable even at run-time so as to adapt to the changing environments and requirements. It is cost-ineffective and time-consuming to restart a running WS-BPEL instance from scratch after the WS-BPEL process is changed. Instead, a WS-BPEL instance had better be transferred to the updated process. Current approaches to validity checking of instance migration are too conservative...
CMMI(Capability Maturity Model Integration) is a process framework which is organized by goals, practice and process area. The Maturity Level 3 stressed that the project level process must be tailored from the organization level process, that is to say, no matter how the project level process changes, it must satisfy the constraints of the organization level process. However, companies usually prefer...
WS-BPEL processes can facilitate service discovery when the services have multiple interfaces in certain order. Current approaches derive the abstract WS-BPEL processes directly from the corresponding executable ones by hiding or omitting the internal activities. However, these simple approaches may prevent the services from being found by valuable potential partners at service discovery stage. To...
In services and cloud computing, processes need to be continually adapted to changing environments and requirements. Undisciplined process adaptation could easily lead to data flow anomalies, e.g., input missing for some activities in the process. In this paper, we study the problem of data-flow-correctness-preserving adaptation and propose three important criteria that can maintain the data flow...
With the component-based development becoming the mainstream of software development, original component technologies focusing on describing the static information of components like interfaces and interactions seems to be weak in today's distributed and open software environment. In this paper we propose a new component model with component's behavior introduced in, supporting a flexible and extendable...
Next generation communication will offer a wide range of services available to users anywhere at any time, which needs the heterogeneous network to support. Enabling users access service resource effectively across heterogeneous network enhance the users experience. This paper presents an intelligent handover control model based on selection strategy for aiding users handover in this'one user with...
