WebSphere brand IBM WebSphere Premises Server, Version 6.1.x

Data Capture and Delivery controller

A Data Capture and Delivery controller is a computer located near the edge of the RFID system. It is the network node that controls a set of I/O devices on the edge of the system, for example the motion sensors, antennae, and light tree of a dock door in a distribution center.

Note: The terms edge controller, Data Capture and Delivery, remote Data Capture and Delivery, and local Data Capture and Delivery all refer to the same functional concept, and can be used interchangeably most of the time. These terms refer to the portion of the RFID system that interfaces directly with the physical readers, collecting the raw data and performing some basic processing. Starting with the WebSphere® RFID Premises Server 6.0 release, this functionality can run as part of the WebSphere Premises Server (local Data Capture and Delivery), or on a separate processor (remote Data Capture and Delivery) to distribute load. In previous versions of WebSphere RFID Premises Server, this functionality running on a remote processor was referred to as an edge controller. For simplicity and compatibility with previous versions of the product, the term edge controller is still used in the product documentation.

Data Capture and Delivery controllers control I/O devices, filter tag information, and send tag information to the WebSphere Premises Server for additional processing. The Data Capture and Delivery software consists of various agents that are delivered as OSGi bundles and activated on the Data Capture and Delivery controller. These agents facilitate the delivery of tag information that is captured by the Data Capture and Delivery controller from the I/O devices and delivered to the WebSphere Premises Server through the MicroBroker.

WebSphere Premises Server supports several Data Capture and Delivery controllers. For information on the IBM® device validation program and supported devices, refer to the IBM Ready for WebSphere Premises Server solutions page at: http://www-304.ibm.com/jct09002c/gsdod/weblistfilter.do?prog=RFWSRFID&tab=1

The components include:

There are also additional agents to transform data formats, manage configuration, handle alerts, and manage general health notification.
