WG81 data description issues

enter your presentation title 33

EUROCAE WG81 deals with Simulator Interoperability

interoperability => data exchange => data description

Data structure is described using OMG’s UML : a graphical notation

class Classes A ircraft + company :String + registration :String class Classes A ircraft + company :String + registration :String StateVector + altitude :Real + speed :Real +groundVector class Classes A ircraft + company :String + registration :String StateVector + altitude :Real + speed :Real Position2D + latitude + longitude +position +groundVector

BUT no choice yet of a technology that would allow actual interoperability on the wire This is a political choice, and nobody can impose its view to other WG members !! XML, IDL-CDR, HLA, ProtoBuf, ASN.1, etc…

OK

then all participants of a given interoperability exercise have to agree on the technology…

One crazy guy may say “OK let’s do it !”… BUT what about changes in the model to add exercise specificities ???

Introducing MDA

enter your presentation title 38

Solution: work on the UML model,... Model Driven Architecture the UML model is the reference the UML model is machine-readable via the XMI representation transformation rules are specified to generate the technology model and let the machine generate the technology artefacts,

IDL

UML XMI

that is the technology-specific model to describe data (XSD, IDL, FOM,…)

Some MDA vocabulary

enter your presentation title 39

MDA was ‘theorised’ by OMG in the early 2000 Describing the world imposes multiple levels of abstraction Twin engine jet Airbus A321neo G-NEOX from British Airways instantiation classification instantiation classification MDA then introduces the concept of metamodel as a taxonomy for buiding models metamodel model

Further MDA vocabulary

enter your presentation title 40

Technology agnostic (PIM) Technology model Domain model Model Metamodel Technology specific (PSM)

Transformation rules

Beyond WG81 : domain model issues

enter your presentation title 41

Multiple domain metamodels Complex domain metamodels Different patterns to express data structure semantics Different machine-readable representations Not limited to data description Multiple ways to implement a given semantic Worse: variable support of machine-readable formats by domain model editor vendors !? Example: MEGA, which uses its own XML representation (not XMI) Example: the XMI produced by Enterprise Architect is not 100% compliant to the UML metamodel Example: UML describes use cases, workflows, components, state transitions, sequence diagrams, etc…

Introducing the IOP model

enter your presentation title 44

The IOP model is dedicated to data structure description gathers common data structure semantics is specified along OMG guidelines, and offers an XMI representation name scoping specialization / generalization composition substitutability has a minimal and simple metamodel no ambiguity, one single way of expressing a given semantic

The IOP model is the intermediate model (“modèle pivot”) in the transformation of Domain to Technology

Creating an ATM FOM

With Martin Johansson Pitch Technologies

Webinar of June 10, 2020 HLA & Air Traffic Control Simulation 47

High Level Architecture (HLA) Terminology

• Each system is called a federate
• Federates connect to a Runtime Infrastructure
• Together they form a Federation
• The RTI provides services like publish-subscribe information exchange,

synchronization and management

• The information exchange is based on a Federation Object Model (FOM)
• A session is called a Federation Execution

The leader in standards based interoperability

Pitch Booster

Connect simulations across WAN with performance and fault tolerance

Multi-sites connection challenges

• How to connect resources and simulators

distributed in one or multiple sites?

• How to best use the bandwidth?
• How to improve reliability?
• How to build an architecture easily

manageable and scalable?

Site 1 Site 2 Site 3

VPN solution

• Advantages with VPN
• Many commercial versions available
• All types of communication
• Problems with VPN:
• Your simulator is no longer on your

local network, it is on the VPN

• All computers from everyone are now
• n the same (virtual) network. They

can do anything with each other. This is unsafe, for example :

• Not as efficient and fault tolerant
• Uses more bandwidth
• Difficult to manage, since you ended to be on the

VPN

67

VPN space Site 1 Site 2 Site 3

Pitch Booster Advantages

• Pitch Booster builds upon and works with

existing, security mechanisms (firewalls, bulk encryption, etc)

• Each resource stays on its own LAN
• Pitch Booster introduces additional

security:

– Policies to decide which other nodes each node can talk to – Policies to decide which resources on a LAN that can participate – Only the simulation application, not the entire host, can use the Booster. Safer than VPN

• Upcoming version (v2.5) will introduce 2

new Booster to Booster connection modes:

– Encrypted – Authenticated

Connecting federates without Pitch Booster

• Classical solution: VPN:

– Tunneled sites: one virtual LAN – Traditional RTI communication – Unaware of WAN links – Creating a communication channel between each federate

Connecting federates with Pitch Booster

• Pitch Booster Advantages
• Security
• 1 port to open
• 1 machine per network
• Optimisation of network bandwidth
• Data compression between Booster

nodes

• Improved reliability
• Mask network hickups
• Reduce packet loss
• Design to recover from failures without

federate affection

• From upcoming v2.5, connection between

nodes could be:

• Encrypted
• Authenticated using certificates and

trust chain
