-## Introduction
+The Open Real-Time Ethernet (ORTE) is open source implementation of
+RTPS communication protocol. RTPS is new application layer protocol
+targeted to real-time communication area, which is build on the top of
+standard UDP stack. Since there are many TCP/IP stack implementations
+under many operating systems and RTPS protocol does not have any other
+special HW/SW requirements, it should be easily ported to many HW/SW
+target platforms. Because it uses only UDP protocol, it retains
+control of timing and reliability.
-In the ORTE project we are developing communication middleware under the OMG Data Distribution Service (DDS) for Real-Time Systems specification (OMG Document formal/07-01-01). The specification defines a service for efficiently distributing application data between participants in a distributed application.
+## News
-The recently-adopted DDS specification is divided into two components. First defines an Application Level Interface and behavior of a DDS that supports Data-Centric Publish-Subscribe (DCPS) in real-time systems. Second optional Data Local Reconstruction Layer (DLRL) allows distributed data to be shared by local objects located remotely from each other as if the data were local. The DLRL is built on top of the DCPS layer.
+* 2012-08-15
+ [ORTE 0.3.3 released](https://sourceforge.net/projects/orte/files/orte-0.3.3/).
+ This is mostly a bugfix release.
-The DDS specification also includes a platform specific mapping to IDL and therefore an application using DDS is able to switch among DDS implementations with only a re-compile. DDS therefore addresses 'application portability.'
-The specification does not address the protocol used by the implementation to exchange messages over transports such as TCP/UDP/IP, so different implementations of DDS will not interoperate with each other unless vendor-specific “bridges” are provided.
+## Introduction
-One of the transport protocol suitable for DDS communication is Real-Time Pusblish Subscribe (RTPS) wire protocol defined by OMG (OMG document formal/06-08-02). The RTPS was specifically developed to support the unique requirements of data-distributions systems. It's a field proven technology that is deployed in thousands of industrial devices.

-OpenDDS is an open-source C++ implementation of the Object Management Group's specification "Data Distribution Service for Real-time Systems". OpenDDS is built on the ACE (ADAPTIVE Communication Environment) abstraction layer to provide platform portability. OpenDDS also leverages capabilities of TAO (The ACE Orb), such as its IDL compiler and as the basis of the OpenDDS DCPS Information Repository (DCPSInfoRepo).
