The Open Real-Time Ethernet (ORTE) is an open source implementation of
-Real-Time Publish-Subscribe (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.

* 2013-10-05 We are preparing a new release that will feature Android
support. Stay tuned and/or test the version from our
[git repository](http://sourceforge.net/p/orte/orte/ci/master/tree/).
[ORTE 0.3.3 released](https://sourceforge.net/projects/orte/files/orte-0.3.3/).
This is mostly a bugfix release.
-## Introduction
-
-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.
-
-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.
-
-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.
-
-One of the transport protocol suitable for DDS communication is
-Real-Time Publish 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.

+ Specifications
+
+* [Data-Distribution Service (DDS) related standards](http://www.omg.org/spec/#DDS)
+ – ORTE implements the RTPS protocol. It offers its own API, not the
+ DDS API.
+* [The Real-time Publish-Subscribe Wire Protocol (DDSI-RTPS)](http://www.omg.org/spec/DDSI-RTPS/)
+ – this is a newer version of the protocol implemented by ORTE.
+* [[Real Time Publish-Subscribe (RTPS) 1.0|rtps1.2.pdf]] – ORTE
+ implements this version of the protocol.
