APPARATUS AND METHOD FOR SUPPORTING QOS IN MIDDLEWARE FOR DATA DISTRIBUTION SERVICE

摘要

Disclosed herein are an apparatus and method for supporting Quality of Service (QoS) in middleware for Data Distribution Service (DDS). The apparatus includes a QoS policy analysis module, a QoS policy management module, and a QoS policy process module. The QoS policy analysis module extracts a set of QoS policies set up by Data Centric Publish Subscribe (DCPS) and associated with publication/subscription, and analyzes the QoS policies. The QoS policy management module determines the consistency of QoS policies of the DDS, and negotiates QoS policies for DDS communication. The QoS policy process module handles the QoS policies of the DDS.
