15. Extensible Types (DDS-XTypes)
• Enables dynamic upgrades
• Types can evolve while maintaining backward
interoperability
• Essential for large and mission-critical systems
FINAL
• Can’t be modified or derived
• All primitive fields are final
EXTENSIBLE <default>
• Type can be extended, but not modified
• Extensions can only appear at the end of the
type definition
MUTABLE
• Type can be reordered and/or modified

@Extensibility(MUTABLE_E
XTENSIBILITY)
struct TrackData {
long id;

long y;
long z; //@Optional
};
C/C++
typedef struct TrackData {
DDS_Long id;

DDS_Long * z;
};

22. Turbo Mode (Experimental)
• As sending rate changes, automatically adjusts
QoS to maintain optimal performance
• Improves performance in burst traffic scenario
– High throughput at high sending rate
– Low latency at slow sending rate
• Supported by new perftest

23. Auto Throttle (Experimental)
• Improves latency and jitter in high throughput
conditions
• Automatically adjusts DataWriter send rate and send
window size in reliable communications using protocol
feedback:
– Send window occupancy to control the send rate
– NACK messages to control the send window size
• Tradeoff
– May increase CPU usage in sending machine (active wait)
– Slightly reduces throughput for small data sizes (<10%)

43. CodeGen 2.0 (Experimental)
• Reduce code generation time especially when dealing with
large IDL files and large number of IDL files
• Ease customizations and extensions to code generation
• Usability
– Apache Velocity (VLT) templates are used in place of XSL
• Performance
– With small IDL files, performance is 6x faster (server mode)
– With a large IDL file (2,000 structs) CodeGen 2.0 is >10x faster

44. Migrating to 5.1
• No API changes required
– Exception: Removed “_exp” suffix from XML
Application Creation APIs
• Must regenerate code
• Builtin QoS profile provided for 5.0
interoperability
• Monitoring and administration topics are not
compatible with 5.0
– Now leveraging XTypes for future forward
compatibility
