2003.8.14 USA Blackout☐ Largest blackout in US history, affecting over

50 million people

☐ A grid overload situation leding to a domino effect that tore down 100 power plants

☐ One of the root causes for the blackout was the communication’s infrastructure inability to maintain QoS in overload situations

Smart CitiesTrends☐ Smart Cities addresses several

problem spaces from traffic management, to parking, conditioning, etc.

Challenges☐ Some of the key challenges in

enabling the smart city vision are:☐ The ability to gather data from a

dynamic environment ☐ The necessity to distribute and

process potentially very large volumes of data

☐ Security

OpenSplice Vision

OpenSplice has a very simple goal:

☐ Making it easier to build, test, integrate, and deploy high-performance, scalable, and fault-tolerant distributed systems

☐ v6 makes this the art of the possible with the introduction of several ground breaking innovations

Key InnovationsMultiple Architectures☐ Unique configurable Federated or Standalone deployment options

allow you to match performance, scalability and fault tolerance characteristics to evolving system needs; reducing both initial and lifetime development costs

Multiple Paradigms☐ OpenSplice v6 delivers the right solution to the right problem

through an expanding range of ‘interaction patterns’ including: Publish/Subscribe, Distributed Object Caches and Remote Method Invocation (RMI)

Key InnovationsUnrivalled Connectivity☐ The new OpenSplice Gateway delivers integration

support for over 80 connectors to other messaging technologies (e.g. JMS & AMQP), proprietary, and Web Technologies (e.g. W3C Web Services & RESTful)

Tools☐ The new OpenSplice Tester greatly simplifies the testing

of testing DDS-based distributed systems

Deployment Options

☐ OpenSplice DDS v6.x introduces a runtime configuration parameter to select between a federated and standalone deployment option

☐ When deployed standalone OpenSplice DDS is a library that manages application-wide communication

☐ When deployed federated OpenSplice DDS is a set of libraries and daemons that manage node-wide communication

deployment architecture that makes

the most sense for your use case.

Vehicles Monitoring☐ Suppose you want to build an application with DDS to deal

with vehicle monitoring

☐ For instance we might want to pilot autonomous vehicles, or perhaps we are interested in road safety, etc

☐ Too keep the application simple let’s focus on the following aspects:☐ Vehicle Status, e.g., where is the vehicle, how fast is it moving, in

which direction, etc.☐ Collision Alert, e.g. is my vehicle about to hit something?

Copyrig


ll Rights Reserved.

Ope

nSpl

ice

DD

S

Data Model☐ Based on the problem description we can easily figure out that

we need at least two different topics. One to represent the vehicle status another to alert about possible collision

struct VehicleStatus { long vid; // Vehicle Position long x; long y; // Vehicle Size long width; long height; // Vehicle Motion Vector long dx; long dy;};#pragma keylist VehicleStatus vid

struct CollisionAlert { long thisVid; long thatVid; float distance;};#pragma keylist CollisionAlert
