3 The Open Real-Time Ethernet (ORTE) is an open source implementation of
4 Real-Time Publish-Subscribe (RTPS) communication protocol. RTPS is an
5 application layer protocol targeted at real-time communication area,
6 which is built on the top of standard UDP stack. Because it uses only
7 the UDP protocol, it retains control of timing and reliability. Since
8 there are many TCP/IP stack implementations under many operating
9 systems and RTPS protocol does not have any other special HW/SW
10 requirements, it should be easily ported to many HW/SW target
11 platforms. ORTE currently runs on Linux, FreeBSD, Windows, Android and

17 * 2015-01-30 We setup a [buildbot instance](http://compile.felk.cvut.cz:8011/waterfall).
18 * 2013-10-28 [ORTE 0.3.4 released](https://sourceforge.net/projects/orte/files/orte-0.3.4/).
19 It features Android support.
20 * 2013-10-05 We are preparing a new release that will feature Android
21 support. Stay tuned and/or test the version from our
22 [git repository](http://sourceforge.net/p/orte/orte/ci/master/tree/).
24 [ORTE 0.3.3 released](https://sourceforge.net/projects/orte/files/orte-0.3.3/).
25 This is mostly a bugfix release.

41 implements this version of the protocol.
45 ORTE can be downloaded from
46 [a project page at SourceForge.net](https://sourceforge.net/projects/orte/files/).
48 Development happens mainly in topic branches of
49 [our git repository](https://rtime.felk.cvut.cz/gitweb/orte.git/heads),
50 which is mirrored to [Github](https://github.com/CTU-IIG/orte).
52 Note that [old releases](http://sourceforge.net/project/showfiles.php?group_id=51629&package_id=108732) are located elsewhere.
56 ORTE is collectively maintained by Michal Sojka, Pavel Píša and Petr
57 Smolík. You can submit an

70 OpenDDS is an open-source C++ implementation of the Object
71 Management Group's specification "Data Distribution Service for
72 Real-time Systems". OpenDDS is built on the ACE (ADAPTIVE
73 Communication Environment) abstraction layer to provide platform
74 portability. OpenDDS also leverages capabilities of TAO (The ACE
75 Orb), such as its IDL compiler and as the basis of the OpenDDS DCPS
76 Information Repository (DCPSInfoRepo).
80 The distribution provides an open-source Java-based DDS-DCPS
81 implementation. The purpose of this implementation is pedagogical

85 * [SQLbusRT](http://sourceforge.net/projects/sqlbusrt) is a software
86 package which enables SQL in a publish subscribe environment with
87 real time provisions. The software package finds it usage in:
89 * Real time measuring environments (data acquisition),
90 * Fast messaging systems,
91 * Real time database in machine automation, and SCADA systems
93 * Military battlesystems
96 * [PyPubSub](http://pypubsub.sourceforge.net/) (short for Python based
97 Publish Subscribe) is a framework for implementing a publish
98 subscribe mechanism into a Python application.
102 We are aware of the following uses of ORTE:
106 * ORTE as core message exchange mechanism in an aerodynamic wind
107 tunnel automation project, for one of the main windtunnel
108 facilities of the world. (see <http://www.dnw.aero> for more
111 * ORTE as message exchange mechanism for the Dutch government: in
112 the automation facility for public water level management in the
113 Netherlands. For an example, see
