Abstract |
|
|
| The Data Distribution Service (DDS) for real-time systems is a middleware standard for Publish/Subscribe (Pub/Sub) which
is an abstraction for one-to-many communication. While DDS is known for supporting many real-time applications successfully,
when applications communicate with others in different network domains over a Wide Area Network (WAN), DDS could face severe
performance degradation, due to the fact that most ISPs do not allow IP-multicast and UDP flows in WAN. In this paper, we propose
a router design for DDS. Keeping DDS semantics, the proposed DDS router provides efficient data distribution over WAN based on
two schemes: overlay multicast and local recovery. Through NS-3 simulations, we show that the proposed scheme improves system
performance significantly in terms of latency and RTT, compared to the current DDS mechanism. |
