4 Introduction-DDS Implementation History Initially started as a part of Gemkomsis CMS development R&D project started in 2004 Supported by Turkish Research and Development Institute CMS based on OMG standards & OACE Common services and functions for naval platforms DDS as middleware MilSOFT DDS continued as a separate product OACE (including DDS) finds its use in multiple projects Turkish Coast Guard SAR Ship CMS Multilink Data Link Processor UAV Image Exploitation system UNCLASSIFIED 4

5 MilSOFT DDS Started with DDS specification 1.0 adopted version Current version compatible with DDS specification version 1.2 C++ API for applications RTPS UNCLASSIFIED 5

6 MilSOFT DDS Implemented Features Minimum Profile (Complete) Minimum profile contains just the mandatory features of the DCPS layer. None of the optional features are included. Persistence Profile (Complete) Persistency profile is completely implemented. Durability service is designed to be fault tolerant. Content Subscription Profile (Partially Implemented) ContentFilteredTopic and QueryCondition features have been implemented. MultiTopic has not been implemented yet. Ownership Profile (Partially Implemented) Only History QoS with depth > 1 feature has been implemented. Object Model Profile (Not Implemented) Contains DLRL and Presentation QoS access_scope = GROUP UNCLASSIFIED 6

7 MilSOFT DDS Architecture Applications use DDS as library No shared memory or DDS service per node Completely decentralized RTPS implemented as the underlying communication protocol DDS Interoperability wire-protocol High performance Zero-copy No dynamic resource (memory, thread, etc) allocation after initialization Multicast address per topic concept UNCLASSIFIED 7

9 What Is RTPS? DDS interoperability wire protocol Real-Time Publish Subscribe (RTPS) Adopted by OMG in June 2006 MilSOFT started to develop RTPS from draft versions Runs over multicast and connectionless best-effort transports Current MilSOFT DDS implements RTPS over UDP UNCLASSIFIED 9

10 DDS Tools MilSOFT DDS Automatic Code Generator MilSOFT DDS SPY MilSOFT DDS Tester UNCLASSIFIED 10

11 DDS Automatic Code Generator Definition of DDS types IDL like interface data stored into XML file Generation of type specific files (FooTypeSupport, FooDataReader, FooDataWriter) From DDS Code Generator GUI From command line using XML file (for automatic builds) UNCLASSIFIED 11

12 DDS Automatic Code Generator UNCLASSIFIED 12

13 DDS Automatic Code Generator Generating middleware specific code using DDS Automatic Code Generator has the following benefits: Application developers do not need to know programming details of DDS API Tool usage speeds up software development as major code is generated by tool It eliminates errors generated while implementing middleware interface It ensures type consistency and interface control through the project Easy management of system internal interfaces from configuration control point of view UNCLASSIFIED 13

14 DDS Automatic Code Generator UNCLASSIFIED 14

15 DDS SPY-Display Data Listens network and displays DDS related information Participating applications to specific DDS Topics each application publishes or subscribes Data itself User selectable listening mechanism Auto Manual Shows data in multiple views Current snapshot of the topic All historical data UNCLASSIFIED 15

16 DDS SPY-Display Data UNCLASSIFIED 16

17 DDS SPY-Inject DDS Data Injects data into selected DDS domain Copy-Paste previously transmitted data and retransmit User can import MS Excel file for data or copy-paste from MS Excel file. Send more than one topic simultaneously with timestamps Great tool for system integration and testing UNCLASSIFIED 17

18 DDS SPY-Inject DDS Data UNCLASSIFIED 18

19 MilSOFT DDS Tester Automated test tool for applications communicating over DDS middleware Allows definition of test suites and test cases Send and receive topic data to/from middleware Compare test results with excepted results and show them as highlighted Show test results (failed tests, successful tests) UNCLASSIFIED 19

21 MilSOFT DDS Performance Test Results Test environment 2 computers with Intel Xeon 3.0 Ghz processors. Fedora Linux 4 Gigabit ethernet switch and LAN Test 1: Latency Ping (Message_size)/pong time(message_size)/2 ~125 microsecond for best 1K message size ~160 microsecond for 1K message size Test2: Round trip with 4 byte ACK Ping different message sizes pong is always 4 bytes ~230 microsecond for best 1K message size ~310 microsecond for 1 K message size Test3: Throughput Measure data size received in one second ~26.5 1K message size Saturates at 4K message size UNCLASSIFIED 21

22 MilSOFT DDS Applications Middleware for CMS, UAV and DLIP product lines GEMKOMSIS CMS Single middleware for handling all communication RM and common services on top of DDS UAV Video Exploitation System Stream data/video over DDS middleware CAVLIS Multilink DLIP UNCLASSIFIED 22

23 Conclusion MilSOFT DDS Developed using mature CMMI-5 processes Fully compliant to standard Successfully used/tested in multiple C2 projects Ready for utilization in projects UNCLASSIFIED 23
