  1. High Level Architecture, HLA Bakgrund och introduktion till HLA Gunnar Öhlund FMV:Infosyst/U 98-04-16 grohd@tranet.fmv.se Utdrag från DMSO-pres vid Industry days -97 Presenterat vid Teknikdag 3 2006-12-12 Gunnar Öhlund 1

  2. M&S Master Plan Executive Agents Architecture Management Group EXCIMS Functional Area Councils Management structure in place No formal management structure Management structure stand-up How Did We Get There? Technical Limited scope simulations, little interoperability prior to 1988 DIS Standards begun DSB: Computer Applications to Training & Wargaming HLABaselineapproved ALSP- linking of Service wargames SIMNET HLA begun 88 89 90 91 92 93 94 95 96 • DEPSECDEF Memo • EXCIMS and DMSO established DoDD 5000.59 ServiceM&S Offices established Management

  3. Interfaces to live players Key: Reusable across all simulation systems Reusable across a simulation domain unique Reuse Data interchange standards, authoritative sources Information, analysis, and employment assistance Conceptual Models Recommended Practices Repositories Standard Object Models Instrumented Ranges Weapon Systems Simulations IndividualCombatants Real-world C4I environment, military systems, doctrine SupportUtilities HLA Interface Specification Runtime Infrastructure Communications

  4. Industryconcepts Previous DoDarchitecture efforts High Level Architecture (HLA)Development Process Overview DoD Policy Issued 10 Sept 1996 Mar 95 Aug 96 Prototypes Evolution Initial definition of HLA Baseline definition of HLA DoD-wide Architecture Management Group ( 16 major simulation programs; developers were 35% government, 12% FFRDC, 5% academia, 48% industry )

  5. The High Level Architecture (HLA) • Architecture calls for a federation of simulations • Architecture specifies • Ten rules • define relationships among federation components • Object Model Template • specifies the formin which simulation elements are described • Runtime Interface Specification • describes the ways simulations interactduring an operation Live Participants Interfaces toLive Players Support Utilities Simulations Interface Runtime Infrastructure (RTI) Federation Management Declaration Management Object Management Ownership Management Time Management Data Distribution Management The HLA is not the RTI; the HLA says there will be an RTI that meets HLA requirements but it doesn’t specify a particular software implementation

  6. And then….. RPR FOM 2.0 HLA to IEEE for standardization Base Object Models Dynamic FOM Link16 BOM HLA adopted by OMG RPR FOM 1.0 DLC API 98 99 00 01 02 03 04 05 06 07… HLA Evolved starts HLA 1.3standard IEEE1516 2000 IEEE1516 2006 HLA 1.3 US DoD ”standard” IEEE 1516 open standard
