1 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 1 Joint Theater Level Simulation Current Federation Status

2 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 2 History 2006-2009 –JMRM FOM Older 1.3 OMT specification –JMRM Federation JTLS + JCATS & few other federates

3 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 3 History 2010 –Ported to1516-2010 HLA specification MSG-68 experimental federation –More strict 1516 data structures –First use of Pitch RTI –MSG-68 included JTLS + many others

4 December 20124 History 2011 –JLVC FOM First JLVC exposure –Federation Mixed 1.3 & 1516 spec (proof of concept) NG Pro 7.0 RTI (dual API) JTLS-JSPA(VRSG) Successful, but required heartbeating MC02 Routing space not suited to1516 Copyright 2012, ROLANDS & ASSOCIATES Corporation 4

5 December 20125 2012 Federation Work Two efforts –Federation for SEESIM new 1516 “JC” FOM –Link to MUSE 1516, future JLVC FOM Copyright 2012, ROLANDS & ASSOCIATES Corporation 5

6 December 20126 2012 Federation Work SEESIM Federation –The “JC” FOM Like MSG-68 FOM Uses extensions for SEESIM –Allows several object owning federates –May lead into future MSG-106 work –Used Pitch RTI and Pitch tools federate locations widely separated Use Booster (network tunneling) Had many remote IEs, only one face-to-face IE –Connected state (RTI), no time management Copyright 2012, ROLANDS & ASSOCIATES Corporation 6

7 7 2012 Federation Work Linking JTLS-MUSE –JLVC FOM “prototype” 1516-2010 Not using JLVC’s MC02 routing spaces –NG-Pro 7.1 RTI Un-connected state (RTI), no time management –We intended for millions of entities… December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 7

8 8 SEESIM 2012 16-19 Oct Annual JTLS exercise –Included this experimental federation Federated game ran synchronized with operational game –JTLS-JCATS –Determine if federation was viable for NTF, etc. 10 country sides –Bulgaria, Croatia, Serbia - JCATS –All others - JTLS 8December 2012

9 Copyright 2012, ROLANDS & ASSOCIATES Corporation 9 SEESIM 2012 16-19 Oct Object counts: –JTLS (142 K) Albania, Ukraine, etc. – JCATS1 (16 K) Bulgaria –JCATS2 (62 k) Croatia –JCATS3 (0) Italy –JCATS4 (7k) Serbia Vignettes –Ships collide –Foreign sides cooperate to fight a forest fire 9December 2012

10 Copyright 2012, ROLANDS & ASSOCIATES Corporation 10 SEESIM 2012 16-19 Oct Data coordination taken from JMRM SEESIM nations able to use simulations they owned and federate for the 1 st time All simulations properly reflected activity in other simulations Very small hardware requirement –5 laptops in Tech Control (Sophia) Very small manpower, 5 people* 10December 2012

11 Copyright 2012, ROLANDS & ASSOCIATES Corporation 11 SEESIM 2012 16-19 Oct Insufficient testing prior to event Crash/Fail procedures –Not developed during IE tests –Developed during the event Could have used – 1 R&A Engineer and 1 LLNL Engineer –Few more face-to-face tests Weapon interactions not used Resupply not implemented Would like ownership transfer!!! 11December 2012

12 JC Federation (SEESIM) vs. JMRM Federation Comparison

13 Capabilities Comparison JC (SEESIM) Federation Aggregates –Full unit hierarchies –Each having few attributes Entities –Selected units full entities Ships –Mounted entities JMRM Federation Aggregates –Full unit hierarchies –Each with full attributes Entities –JCATS published some –JTLS entity lists only Ships –JTLS only Resupply Weapon Fire/Detonation

14 Capabilities Comparison JC (SEESIM) Federation Air Missions –Single aircraft –Fixed load –No HRU lifting Convoys –Truck only No Time Management Object control –No passing JMRM Federation Air missions –Multi-aircraft –Loads mapped –Insert Extract, etc Convoys –JCATS reflects Time Managed Object control –passing

15 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 15 Federation Discoveries Using JC Federation (SEESIM) –Joining problems with > 100 K objects and > 4 federates that own objects –Overcome difficulties with poor connections –Remote testing lessons

16 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 16 Joining Problems Use specially configured Pitch Extender –Block receipt of duplicate updates Modified HIP to tick less often –Tick : to suspend processing for RTI work Planned to use a two phase startup –(1)Federates withhold requests and replies for updates –(2)Send full updates, process everything then begin to run

17 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 17 Poor Network Problems Reduce the count of objects –For the offending federate Use Pitch Extender –Not greatly effective –A bad connection is a bad connection

18 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 18 Remote Testing Advantages –Everyone worked from their own office –Saved travel expense –Can test more frequently, shorter –As few a 1 federate could be testing –R&A game running/federated 24/7 –We always had a Pitch expert during scheduled testing*

19 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 19 Remote Testing Disadvantages –Limited by Skype Single thread of testing items –People not involved in current test had to wait –Time difference between offices

20 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 20 Federation Discoveries Using JLVC federation (MUSE Link) –Objects require heart beating –Guarantee all objects discovered/updated –Realistic looking states Eg. target launchers

21 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 21 Discoveries from linking with MUSE Ellen will brief…

22 December 2012 Copyright 2012, ROLANDS & ASSOCIATES Corporation 22 Where We Stand JTLS can federate using either FOM –Publish/Subscribe aggregate and entity objects –Publish/Subscribe Firing/Detonation interactions –Other interactions possible No plans to link using JLVC (NG Pro) May join the MSG-106 effort –Uses something like the JC FOM (Pitch ?)
