Towards massive distributed Simulation
The Navy identified networked trainers as a key requirement in future training systems.
Networking capability exists in many simulators, but frequently the capability is cumbersome
to set up and difficult to use, particularly when participants are not collocated. In addition,
the speed is not yet available to support the requirements for real time simulation across
distributed networks. There are work-arounds, but they do not currently support full, real time
simulations. The ability to easily and seamlessly link multiple training devices into the same
training scenario will greatly enhance the quality and effectiveness of the training.
[…]
Effective networking of simulators will require a common architecture and industry wide
standards. Over the years, the High Level Architecture has provided the foundation for
this standard, but going forward these standards will need to expand to accommodate
new capabilities and new participants. The NASMP needs normalized, consistent
architecture and a well articulated business case to justify the investment in the NASMP.
Is HLA enough?

The Simulation Standard : HLA (IEEE 1516)
© NADS 2011
▪
HLA is a mature standard for simulation, with next major
milestones:
□ Born in early 90’s sponsored by US DoD
□ US DoD std in 1998 (HLA 1.3)
□ IEEE std in 2000 (IEEE 1516-2000)
□ New release in 2010 (IEEE 1516-2010), best known as HLA
Evolved.
▪
HLA is an architecture for doing simulation with:
□ An interface spec. Defines a common API for the HLA
middleware : Run-Time Infrastructure (RTI).
□ An Objet Model Template (OMT). Defines a metadata
model for HLA simulations.
□ Some Rules that simulation must follow to be HLA
compliant.

The Simulation Standard : HLA (IEEE 1516)
□ Historically, HLA has had some problems ….
▪ Lack of real time features
▪ The wire protocol is not standarized.
▪ Mainly you only have interoperability and reusability to the system
level
▪ Interoperability with other real systems is very limited.
□ HLA evolved improves some things:

Is HLA enough?
1. HLA Evolved still lacks of a wire protocol.
2. QoS are very limited.
3. Web Services are not always the best way of integrating
with real-time critical systems
4. HLA RTIs performances are not enough for massive
distributed simulation federations with real time
requirements.
