  1. US Army Tactical C2 Interoperability Services: Publish and Subscribe Server (PASS) and Data Dissemination Service (DDS) Sam Easterling Army PM Battle Command 2 DEC 09

  2. Outline • What are PASS/DDS in a nutshell? • Operational Context • Technical Detail • Summary

  4. PASS/DDS (in a nutshell) • Built to support many-to-many data exchange requirements emerging from stovepiped architectures • Publication/ Subscription mechanism • Does not impose a model on the way the application conducts the Business of War. • Not a database, but published data is stored for future subscriptions with a time-to-live • Flexible methodology allowing for insertion of new schemas and message exchange • Web Services/SOAP and XML • Runs over HTTP(s). • Internet protocol • Protocol knows how to deal with latent and ‘dirty’ networks • Data agnostic • But…. ABCS message exchange is based on PASS schemas

  5. Data that Battle Command Exchanges via PASS / DDS • Friendly Position Reports (ground and air) • Enemy Situation Reports • Sensor tracks • Military C2 Graphics / Battlespace Geometries • Significant Activities (SIGACTS) • Targets • Airspace Control Orders (ACO) • Weather • Task Organization Information • Addressbook Change Notification • Indicators and Warnings

  6. Each US Army unit in OEF has a PASS node at CJTF, BCT, BN HQ • Also in RC(S) @ 57th SIG, MEB-A • Co-located with every CPOF Master Repository to enable exchange • Also planned installation in IJC HQ to enable interoperability services with NATO apps

  11. DDS Uses a Pub-Sub Approach 1. Providers Advertise (the data they will publish) 2. Consumers Subscribe (to their server for data) 4. Servers match advertisement, subscription and publish metadata 3. Providers Publish (push data to their server) There are multiple collaborating servers within the DDS network 5. Servers Publish (push data to consumers) Clients only communicate with a single server

  12. DDS and advertisements • DDS uses advertisements to “tell everyone on the network” that data exists at a certain node • DoD Discover Metadata Specification (DDMS) version 1.3 is the standard for the advertisement • What type of data • Data description • Who has access to the data • Clients subscribe to advertisements • Clients provide the “call back protocol” method to deliver data • HTPP(s), UDP(s) (DDS version 2.0) • Publishers, publish data for an advertisement • Once a publisher, injects data, and a match occurs against the subscription, data is delivered to the client

  13. DDS versus PASS • Data is global • Unlike PASS which was a application for data dissemination within the TOC, DDS was developed with global data as the main paradigm. • PASS compatibility • Will keep compatibility with current PASS • Usage of a PASS/DDS bridge to mach advertisement to topic • Not tied to any software baseline because of backward compatibility • Better security model than PASS • Complies with NCES security policies • Meets DOD guidelines for security.

  14. PASS to DDS Evolution

  15. Sample metadata • <advertise commandDateTime="2006-02-15T11:04:16.765-05:00" userID="mcsuser" xmlns=""> • - <metadata> •   <ns1:title ns2:classification="U" ns2:ownerProducer="USA" xmlns:ns1="" • xmlns:ns2="urn:us:gov:ic:ism:v2">MCS_DEMO</ns1:title> •   <ns3:description ns4:classification="U" ns4:ownerProducer="USA" xmlns:ns4="urn:us:gov:ic:ism:v2" • xmlns:ns3="">MCS_Desc</ns3:description> • <ns5:creator ns6:classification="U" ns6:ownerProducer="USA" xmlns:ns5="" • xmlns:ns6="urn:us:gov:ic:ism:v2"> • -<ns5:Organization>  <ns5:name>MCS</ns5:name>   </ns5:Organization> •   </ns5:creator> • - <ns7:subjectCoverage xmlns:ns7=""> • - <ns7:Subject> • <ns7:category ns7:label="Ground" /> •   <ns7:keyword ns7:value=“FBCB2" /> •   </ns7:Subject> •   </ns7:subjectCoverage> • - <ns8:temporalCoverage xmlns:ns8=""> • <ns8:start>2006-02-15T11:03:55-05:00</ns8:start> •   <ns8:end>2006-02-15T16:03:55-05:00</ns8:end> •   </ns8:temporalCoverage> • - <ns9:geospatialCoverage xmlns:ns9=""> •   <ns9:lowerCorner>-170.0 16.0</ns9:lowerCorner> •   <ns9:upperCorner>-169.0 17.0</ns9:upperCorner> •   </ns9:geospatialCoverage> • <ns10:security ns11:classification="U" ns11:ownerProducer="USA" • ns11:releasableTo=“MCSGroup FBCB2Group" • xmlns:ns11="urn:us:gov:ic:ism:v2" xmlns:ns10="" /> •   </metadata> •   </advertise>

  16. Key Advertisements Subscriptions Published data How DDS Works • DDS client, discovers DDS node location through the use of discovery services • Publisher • Advertise their data, DDS server to server protocol propagates advertisements to other nodes • Publish data to local DDS node. DDS node merges subscribers of published data from save DDS node and send data to node then DDS nodes stores based on TTL • Subscribers • Subscriber, specify advertisement and data filters • DDS node will match subscriptions to advertisements and forward subscription to owning DDS nodes • When DDS node receives published data, it sends to subscribers • NCES Security • Authenticates and authorizes DDS nodes, publishers & subscribers NCES Services Security Sub 1 Discovery • DDS Nodes Sub 2 DDS Subscribe Advertise DDS Advertise Publish Publisher Sub 1 Overlap in subscriptions from same DDS node are only sent once Sub 2

  18. Summary • PASS / DDS are used by US Army Battle Command systems to share ‘common operational picture’ data at tactical echelons • XML payloads with metadata to enable appropriate AOI/temporal queries and identify releasability • HTTPS-based with soft certificate-based security model • Supporting initial coalition interoperability with UK (JADOCS) and ISAF (CPOF, JOCWATCH, COP LM)

  19. Backup

  20. Security policyDDS has a comprehensive security model • Functional Validation • Users have privileges to functionality based on their group membership • Clearance Classification • Users have privileges to publish or subscribe based on their security classification and releasibility for data. • Users have privileges to publish or subscribe based on the rights associated with the advertisements. • Advertisements carry security classification • Need to know • All functionality for access is based on users being members of groups • Advertisements carry need to know • Advertisement is only available to subscribers who are in the groups which are specified in ‘Releasable To’ field of the Advertisement • Single Sign On under Windows (clients)

  21. MIP Deployment Summary • MIP Ver 09_4_4_22 is installed on the BCS server at IJC HQ. MIP is receiving data from CPO LM (formally BOM) and publishing it to PASS. We have tested it with CPOF and CPOF is subscribing to PASS and displaying the data. There is one issue with Road graphics they are a point to point line, but they are displaying as an icon. Joel Varanda is sending Venis the unclass PDU for the road. • COPLM is sending the following data through MIP: • Battle field Geometry • NATO and ANA Boundaries • FOBS • COPS • UNITS (not tracks) • NGO/IO Locations • Road (Planned, under construction and completed) • COP LM is not sending the following data • SIGACTS (JOC Watch) • Ground Tracks (GCCS-J) • Air Tracks (TBMCS) • Fires (JADOCS) • LOG (NIRIS)
