ABSTRACT
Distributed information systems for decision support and
e-commerce applications require coordination of multiple
autonomous components and their services to accomplish a set
of global goals. In such systems, a global and often distributed
coordination policy actively governs the coordination among the
distributed components. The policies are used to interpret
messages or events (e.g., job assignments, changes in data)
from the cooperating components, in order to generate tasks with
sequencing constraints. The generated tasks and their
sequencing are then used as a basis for coordination of the
services provided and required by the components. This paper
presents the SWAP architecture that addresses the problem of
dynamic changes in the needs or context of the autonomous
components via change in the coordination policy at run-time.
We present a method in the context of SWAP for the systematic
generation of change coordination plans supporting the
automated switching of coordination policies.
