What network topologies are allowed?
DDS is agnostic to network topologies. All possible network topologies can be used with DDS. What is the span of the transport: LAN vs. WAN?
A DDS data space is agnostic to the network constraints, and can therefore span both the LAN and the WAN. DDS implementations allow application components to be located anywhere— on the LAN or across the WAN. DDS implementations provide mechanisms to deal with firewalls and other restrictions encountered when going across the WAN.
Can the transport support multiple independent and isolated communication paths between the same network endpoints?
Yes, DDS can support multiple independent and isolated communication paths between the same network endpoints. DDS accomplishes this by providing a PARTITION QoS policy, which allows communication between DDS endpoints tagged with the same partition label.
