The document discusses the evolution of simulation as a service (MaaS) within the context of live-virtual-constructive (LVC) training systems, highlighting the challenges of current simulation architectures that are predominantly standalone and lack interoperability. It proposes a layered simulation architecture (LSA) as a solution to enhance integration and leverage existing standards like OMG DDS for improved performance in cloud environments. The text emphasizes the need for an open architecture to facilitate the creation of an M&S apps store, ultimately transforming how simulations are built and deployed.

2. A new Disruption is arriving : using
Simulation as Services
Simulation for
Individual
training
Simulation
for Team
Training
Simulation
for Joint
Training
Simulation
for Concept-Design
& Experimentation
(CD&E)
(M&S as a
Service or
MSaaS)

3. But Simulation Architectures are
not disrupting…
Propietary Architecture
Stand-alone
Simulator

DIS, HLA, TENA
Federation of
stand-alone

Gateways

 Simulation systems are still design to work standalone,
 Existing simulation standards were not designed with a System of
Systems (SoS) approach.
 Interoperability is limited and only at a system level at best
The Challenges

4.  Run over any available platform
 24x7 availability
 Quick scenario set-up
 Over any kind of network
 Fast availability
 Easy search (indexing&tagging)
 Seamless integration
 No error allowed in client side
In integration
In operation
MSaaS will change the way we
build M&S Systems

5. Concept is close to (or inspired
by) “apps” in smart-phones
Sim apps as black-boxes:
users don´t need to know
about:
Security
How the services are
implemented
How to interoperate everything
Certification of Assets : users
got what was promised
The Quest for MSaaS : Looking for
the M&S Apps Store

6. A platform to support the
deployment of Simulation services
in the cloud must be created
Simulation Assets must evolve to a
Cloud Architecture
New business models must be
implemented
What we need to use Sim Assets in
the Cloud?

Here, we will take a look only
in the technical issues

7. A Big Chasm to cross before to go
to MSaaS
Number of features

Simulation Architectures

Simulators with
different architectures
and protocols
Federation of

With existing
architectures even
simple federations
are complex.

How to solve the problem : Going
beyond actual sim architectures

Simulation Network
 Build your assets with an
Open Architecture to avoid
gateways
 Design with Data-Centric
architecture
 Encapsulate the standards
into the platform

Using a Layered Simulation Architecture (LSA) for MSaaS
Layered Simulation
Architecture
C2SIM
DIS
HLA Converging multiple
standards in one common
platfform.
 Leveraging a standard
well known in operational
systems : OMG DDS
(Data Distribution
Services)
 Improving integrability
and interoperability with
common services

11. LSA is trying to provide a solution
to pains found on LVCAR
 Gateway solutions are
difficult to develop, upgrade
and maintain
 Lack of Convergence of
Simulation Architectures
 Lack of common data models,
protocols and data distribution
mechanisms
 Performance requisites are
not guaranteed
 Lack of plug&play capability
 Proprietary Architectures of
the simulators

12. LSA follows an open innovation
approach to solve LVCAR pains

13. 13
Main reasons to use SISO LSA as a Platform for MSaaS
 Provides a SoS architecture
 Provides a common platform to cohabitate
different standards
 Leverage Object Modeling Group (OMG) DDS
standard, to have an open wire protocol
for simulation
 Layered architecture can provide a common
platform to the services in the Cloud

14. 14
Others reasons to use SISO LSA as a Platform for MSaaS
 OMG DDS is useful in any kind of
network and condition. It is available
in almost any type of Operating System,
platform and network.
 DDS can make easier the integration
of Live assets, because DDS is already in
use in many operational systems.
 We can have also a solution to the the
security challenge, using security
profile in OMG DDS std.

15. Where are we now with LSA?
 Nominating standard at SISO by LSA Study Group. Final report
and Product Nomination (PN) available at SISO reflector.
 Several use cases already available, see references in paper.
 PN’s plan is to have a first draft of the standard at the end of 2015
and a full mapping with HLA and DIS at the end of 2016.
