IONA Technologies Celtix and DDS What is DDS

IONA Technologies Celtix and DDS

What is DDS? Data Distribution Service Publish-Subscribe messaging Data-centric NOT Client-Server based Multicast message distribution IDL-defined message payloads Proprietary wire-level protocols (OMG standard soon) No broker daemon process (or single point of failure) OMG Standard – v 1. 0 200? – (RTI, Thales Naval Nederland, OCI) Use cases: Distributed sensor networks…etc. Naval Command & Control Systems; Automotive; Robotics Vendors: RTI NDDS, Prism. Tech Open. Splice

What is Celtix? IONA’s packaged opensource Enterprise Service Bus so inherently Client-Server Commercially supported Endpoint- or Router-deployed Java web service enabler Extensible through powerful plug-in architecture Bob, I’ll let you flesh this out… - I’m sure you have this covered in plenty of existing PPTs…? !

Celtix + DDS: how, what and why? Celtix transport plug-in to send/receive DDS messages Stateful to maintain non-DDS endpoint publish/subscription information Celtix DDS Gateway for interoperability: Between different DDS implementations: NDDS, Open. Splice, Open. DDS, TAO DDS, Between DDS and other asynchronous messaging standards CORBA Event/Notification, JMS, AMQP…etc. Between DDS and synchronous client-server communication technologies SOAP/HTTP Web Service, IIOP CORBA, Tibco, MQSeries…etc. Performant alternative to JMS web service transport (i. e. with DDS entirely abstracted by DDS plug-in used at both client and server) Can connect the data-centric and client-server worlds

Use case 1: DDS – CORBA integration Naval command-control systems (Thales’ Tacticos, LMCO/Raytheon DD(X), Litoral Combat Ship…etc. ) typically utilize both data-centric DDS and client-server CORBA technologies. Celtix DDS gateway can connect those worlds – removing concern for such middleware integration from the C&C system developers. Also applicable in other verticals, such as robotics and automotive, that blend datacentric information from sensor networks with client-server-based system management. DDS sub 1 DDS sub 2 DDS wire protocol Celtix CORBA binding DDS pub 1 DDS binding Celtix v 1. 1 will include Yoko CORBA binding. subscribe(topic) CORBA server push(msg) CORBA client push(msg) IIOP CORBA server

Use case 2: DDS – DDS interoperability In the absence of concensus on a standard DDS wire protocol a Celtix DDS could act as a mediator propagating messages between DDS networks based on different vendors’ DDS implementations.
