Fault-Tolerance

Application Failure / Recovery

Application State is maintained in the shared memory thus allowing very short recovery time

After a failure all distributed state has to be recovered, thus leading to longer recovery times

Fault-Tolerance

Misbehaving Application

Node-wide resource management can contain the impact of misbehaving applications

The effects of misbehaving applications are propagated to the distributed system

Example: Simple Routing

Simple routing can be used in the following cases:¨ A topic has to be routed from one DDS domain to another (or

several) DDS domains

¨ A topic has to be renamed

val simpleRoute = new RouteBuilder { “dds:Circle:1/ShapeType” to “dds:Square:2/ShapeType” }

Extensible & Dynamic Topic Types

The DDS-XTypes Specification defines:

¨ A polymorphic structural type system for DDS topic types – which formalizes extends in several ways the DDS v1.2 type system

¨ A set of standard concrete syntaxes for representing topic types

¨ A set of serialization formats supporting extensible types

¨ A dynamic API for defining Topic Types and DR/DW operating over these types

¨ Suppose that we want to incrementally upgrade the Temperature Sensor with one that produces humidity estimates along with temperature
