About DDS

Benefits of the DDS approach
 

Simple & Powerful Data-Centric Pub-Sub Model
  •   Reduces Risk and Development/Integration Time
  •  Enhances effective performance by delivering the right data to the right place with the right QoS
  •  Standards-based: API and Protocol
1. Unsurpassed Performance and Scalability
Priority-aware no choke-points architecture
2. Builds higher quality systems and lowers TCO
Built-in high-value capabilities
Handles Availability & other “hard problems”
Easy to maintain and Evolve
Leverage multicore
  • DDS Interoperable Wire Protocol uses UDP
  • Low overhead, Unreliable protocol
  • DDS allows application to choose RELIABLE or BEST EFFORT communications
  • RELIABLE setting adds hand shaking and retransmission functions to guarantee data delivery
  • BEST EFFORT setting uses default UDP protocol: no guarantee of data delivery
  • Retransmission of data is dependent on additional QoS settings
  • History Depth must be adequate to save samples that may need to be retransmitted
  • Resource Limits may be applied to force the Publishing application to block until the Subscribing application can handle additional data
