Performance Evaluation of Transport Protocol in Data Distribution Service Middleware

Abstract

The DDS middleware provides powerful support for data dissemination in the distributed real-time and embedded (DRE) systems, and supports multiple transport protocol (e.g. TCP, UDP and Multicast) that affect the end-to-end quality of service (QoS) properties (e.g. latency, jitter and reliability).In order to evaluate the performance of the transport protocol and then evaluate the affection on the DDS middleware QoS, this paper first briefly compares the common DDS implementations, and then presents performance evaluation and analysis of the transport protocol in OpenDDS with different environment configurations, at last presents the conclusion.
