Introduction

A workflow is a step-by-step operation of a process.

A standardize way for automating technical process is still missing.

Enabling workflow in UPnP networks is a first step to close the existing gap between technical- and business-oriented process.

4

UPnP

UPnP is base on a client-server-concept

In order to participate in networking a device needs a unique IP address.

Workflow

In more general definition workflow can be treated as a manual or automated step-by-step operation of a generally known process.

6

Workflow

Business processes are defined by process definition using the XML Process Definition Language (XPDL).

Integrate workflow management system into UPnP network

Two UPnP services– WorkflowControl service– ProcessDefinition service

10

WorkflowControl service

Action – StartWorkflow– AbortWorkflow– GetWorkflowStatus

Done Executing executable

– GetWorkflowResult– RunWorkflow

11

ProcessDefinition service

Action– registerProcess– unregisterProcess
