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

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